6 DESCRIPTION AND TAIL LIFT TERMINOLOGY
6.1 GENERAL
DHOLLANDIA tail lifts are developed and manufactured using state-of-the-art technology, high quality materials and components,
and highly skilled workmanship. They comply with the European CE safety regulations mentioned in the Declaration of Conformity
issued with each lift (unless agreed otherwise for tail lifts exported outside of CE region).
The manual distinguishes between :
1. Column lifts that stop at the vehicle floor [see 6.1.1 below]
2. Columns lifts that travel above the vehicle floor [see 6.1.2 below]
The product names DH-VO* and DH-VH* stand for generic, general purpose lifts. If complemented by a G, the tail lifts DH-VOG* and DH-VHG* refer to special executions adapted to the distribution of gas bottles.
In its travel position, the platform of the column tail lift is stowed vertically behind the vehicle body. Before use, the platform is lowered approx. 15 cm, then tilted open 90 degrees from the vertical travel position to a horizontal work position.

Affixed to the side of the vehicle body, or on the platform
6 DHOLLANDIA
6.1.1 Column lifts that stop at the vehicle floor
These column lifts feature a restricted lifting height from the ground to the vehicle floor
vfh. They are suitable for a wide variety of trucks, trailers and semi-trailers, and are
available with lift capacities ranging from 500 to 2000 kg.
Depending on tail lift model and options chosen, the opening and closing of the
platform can be manual, or actuated by 1 or 2 hydraulic tilt cylinders. See table below:
Type Lift capacity Manual closure Hydraulic closure 0-90
OVH004
Hydraulic closure with adjustable
platform orientation OVH011
DH-VO.07.K1 500 750 kg standard - -
DH-VO.10.K1 750 1000 kg standard optional -
DH-VO.15.K1 1000 1500 kg standard optional optional
DH-VB.15.E1 1000 1500 kg standard optional -
DH-VO.20.K9 1500 2000kg standard optional optional
DH-VH.15.H1 1000 - 1500 kg standard optional optional
Note: where the suffix K1 is replaced by K2, this refers to special technology used to reach a normal vehicle floor height on very narrow
lifts. There is no implications for the operating procedures in comparison to K1 column lifts.
6.1.2 Column lifts that travel above the vehicle floor
These column lifts benefit from a much higher lifting height. The platform travels a
distance X above the vehicle floor vfh. The maximum height vfh2 depends on the
width of the columns. They are designed for a wide variety of trucks, trailers and semi-
trailers, and are available with lift capacities ranging from 500-2000 kg.
Depending on tail lift model and options chosen, the opening and closing of the
platform can be manual, or driven by 1 or 2 hydraulic tilt cylinders. See table below:
Type Lift capacity Manual closure Hydraulic closure 0-90 OVH004
Hydraulic closure with adjustable platform orientation OVH011
DH-VO.07.K9 500-750 kg standard - -
DH-VO.15.K9 1000-1500 kg standard optional optional
DH-VO.20.K9 1500-2000 kg standard optional optional
Note: where the suffix K9 is replaced by K2.K9, this refers to special technology used to reach a much higher level than would
technically be achievable with a regular K9 lift, based on the given vehicle width. There is no implications for the operating procedures
in comparison to K9 column lifts.

6.1.3 Executions and terminology
See below and following pages
DH-VO.07.K1 / K9 MANUAL CLOSURE TERMINOLOGY
See figure below for parts corresponding to numbers in this table
# Description
1 Lift columns: set of 2 columns mounted in a fixed position against the vehicle body. These form the rails within which the lift
runners carrying the platform travel up and down.
2 Cylinder beam: horizontal beam mounted at the vehicle floor. This beam contains the lift cylinder; the drive system consisting
of chains and pulleys; and often also the hydraulic pump unit.
3 Lift cylinder(s): 1 or 2 hydraulic cylinder(s) used to LOWER / LIFT the lift runners, the platform and its load. K1 and K9
executions are equipped with 1 lift cylinder. K2 executions have 2 lift cylinders and therefore offer increased lifting height for a
given column width.
4 Hydraulic pump unit: contains the electric motor driving the hydraulic pump, the oil tank, and the control valves. The unit can
be premounted inside the cylinder beam (if technical parameters allow so), or is mounted separately on the vehicle chassis.
5 Platform: carries the load during lifting and lowering. Manufactured from steel or light-weight aluminium and with a non-slip
working surface. In standard execution, the platform is equipped with a fixed leading edge. Optional roll stops or retention ramps
at the outboard platform edge, are available as an option.
6 Torsion bar(s): powerful spring device hidden inside the platform, assisting with the manual OPEN / CLOSE of the platform (in
case of manual closure).
7 Lift runners: set of 2 slides carrying the platform, travelling up and down in the lift columns. They are lifted and lowered by the
lift cylinder and the drive mechanism (chains and pulleys).
8 Stow lock: set of 2 lock plates mounted on the platform, L+R of the inboard platform edge; and 2 lock plates on the lift columns,
L+R of the cylinder beam. To stow the platform in its travel position, CLOSE the platform from the open work position to the
vertical position. Then LIFT the vertical platform against the underside of the cylinder beam until you hear the hydraulic system
turn in over-pressure.
9 Platform lock: pivoting lock on the near-side lift runner with dual function: 1. Platform in vertical position [on all DH-VO.07.K1]: the hook holds the platform closed against the lift runners. Release the
platform lock to open the platform. 2. Platform in horizontal position [only on DH-VO.07.K1 with foldable platform or retention ramps, not in case of fixed leading
edge]: the lock blocks the platform in work position, and prevents the torsion bar(s) from tilting up the platform. Release the platform lock to close the platform.
Note: the platform lock is only used on column lifts with manual closure, not on lifts with hydraulic closure.
10 Main external control box: mounted in a fixed position at the side of the vehicle or under the body. It contains the electrical
switches to LOWER / LIFT the platform.
11 Centre point of maximum load: point up to which the maximum rated capacity of the tail lift is valid. Beyond that point, the
maximum safe working load diminishes according to the applicable load charts found in section 8 of this manual.

22 DHOLLANDIA
6.2 SAFETY DEVICES
DHOLLANDIA tail lifts are equipped with a multiple safety devices in order to ensure that goods can be loaded and unloaded with
maximum safety for the operator, any incidental bystanders, and the load itself. The following safety devices are incorporated or
recommended on most tail lifts:
Electrical safety valve mounted on the lift cylinder [standard]. The safety valves lock the oil inside the hydraulic cylinders as
long as they are not energized via the electrical controls. The purpose is to secure the platform in its travel position while driving,
or in any other fixed position, in case of accidental failure of a hydraulic pipe (as soon as the electrical controls are released).
DHOLLANDIA safety valves are equipped with a manual emergency control, allowing the operator or repair agent to open the
valve manually in case of electrical failure (see MAINTENANCE AND REPAIR MANUAL).
Mechanical platform lock(s) [depending on model see 6.1.3 from page 7 onwards]. DHOLLANDIA column lifts are equipped
with stow locks and platform locks, to secure the platform in its travel position in case of accidental loss of hydraulic pressure.
Pressure relief valve [standard]. Safety device integrated in the pump unit, enabling the manufacturer and the installer of the tail
lift to limit the real lift capacity to the maximum rated capacity of the tail lift sold, and to protect it against overload while LIFTING.
Pressure compensating flow valves [standard]. Flow valves are integrated in the hydraulic circuits to ensure the platform lowers
at a safe speed, both when empty as when fully loaded.
Marking of the centre point of maximum load [standard]. Tail lifts are not designed to LIFT and LOWER weights corresponding
to their maximum rated capacity over the entire surface of the platform. The maximum rated capacity is only valid at a specified
distance or centre point of maximum load behind the vehicle body. Behind that point marked on the platform, the maximum safe
working load diminishes according to the load diagrams supplied with the tail lift. See also section 8, page 42, on load charts and
correct loading procedures.
Load safety device (LSD) [standard on chain or cable lifts, not used on fully hydraulic lifts]. Both lift runners are equipped with a
chain break protection device (DH-VO*) or cable break protection device (DH-VB*). In the unlikely incident of a chain or cable
breaking, the LSD will jam the lift runner in the lift column, keep the platform relatively stable, and prevent it from dropping more
than 10 cm from its position at the time of the failure.
2-hand external control box [optional]. It is recommended that all column lifts be ordered with a 2-hand external control box,
mounted in a fixed position at the side of the vehicle body. This means that all functions are actuated by means of a control switch
and a safety switch. The compulsory use of the 2 hands to actuate the various lift functions, protects the operator from crushing
his head, limbs or upper body between the LIFTING or CLOSING platform and the rear frame of the vehicle body.
WARNING
ALWAYS stand with both feet on the ground on a free-standing, safe operator position at the side of the body
when operating the external control box (see also 7.5 on page 33). NEVER operate the external control box
from an elevated position, such as the platform or a loading dock.
NEVER reach over or through the platform and the moving parts of the tail lift while trying to operate the lift.
ALWAYS keep your head, limbs and body clear of the moving platform and other pinch points.
Fuses [standard]. A 15A fuse for the electrical control circuit is premounted in the pump unit and in the main external control box
(for most types). A 150 - 250A fuse for the electrical main battery circuit is supplied by the truck manufacturer or by DHOLLANDIA.
Both fuses protect the electrical circuits against short-circuits and amperage peaks.
23 DHOLLANDIA
Tail lift on/off switch [min. 1 compulsory]. Depending on configuration, the electrical power to the tail lift is switched on / off by
means of:
1. A cabin switch (provided by the truck manufacturer or DHOLLANDIA [option OAE503.1]). This switch enables the operator
to switch the control power to the main external control box on / off. If equipped with a cabin switch [option OAE503.2] and a
position sensor [option OVE221], the tail lift can also be set-up to provide a signal if the platform is stowed in its travel position,
or left open.
2. A main battery disconnect switch integrated in the external control box [optional]. This switch enables the operator to switch
the main battery power to the tail lift on / off. If available, the operator MUST switch off the main battery disconnect switch
after each use of the tail lift.
3. A combination of both.
Protection of toes and feet against crushing and sheering [standard]. The cylinder beam or floor extension of the column lifts
type DH-VO* and DH-VH* are usually designed with a rear sloping edge conform EN1756-1 annex B.2.3.1. Despite this design,
the operator must observe following precautions:
WARNING
If the operator on the platform stands to close to the inboard platform edge, protruding toes might be crushed
or sheared between the rising platform and the cylinder beam or vehicle floor. This can cause serious bodily
injury.
Therefore, when operating the tail lift from a position on the platform, ALWAYS stand at a safe distance of
minimum 25 cm from the inboard platform edge.
See also 7.4.3 from page 32 onwards.
Roll stops [optional]. If a platform is aimed at LIFTING and LOWERING loads that cannot be braked or secured by their design
or their method of transportation, the platform MUST be equipped with roll stops that prevent the load from accidentally rolling off
the platform, and hitting the operator or any bystanders. DHOLLANDIA offers a variety of roll stops that can be fitted near the
outboard platform edge, or at intermediate distances. [See also 9.8 from page 65 onwards.]
Visibility of the deployed platform [min. 1 compulsory]. Any platform protruding beyond the extremities of the vehicle, MUST be
clearly visible from all approachable sides in daylight and at night. Check any applicable national or local regulations, as these
can be very strict on the application, size and type of means used. The visibility of the platform can be optimized by:
1. Reflective marking tape applied to the sides of the platform [standard] applied during installation]
2. Platform flags [option OAT020 - 023], mounted to the underside of the platform, near the outboard platform edge
3. Bi-directional flashing platform lights [option OVE201.C], mounted on the platform surface, near the outboard platform edge
4. Warning cones (2 or 4) [widely available] placed around the work area of the platform
5. A combination of 2 or more of the above. The various means above have variable efficiency depending on the direction of
approach and the light conditions (e.g. bright sunlight versus night darkness). DHOLLANDIA strongly recommends a
combination of 2 or 3 means to cover all circumstances.
Guard rails [optional]. Guard rails MUST be fitted in all applications where a significant risk exists that the operator could fall off
the platform and suffer bodily injury. They are compulsory above 2 m lifting height.
Guard rails may be purchased along with your tail lift at the initial order, or may be purchased and retrofitted to your tail lift later.
They are available in a wide range of different executions to suit the particular needs of many applications. Contact your national
DHOLLANDIA dealer for further information. See page 3 for contact info.
Decals [standard]. The tail lifts are supplied with a number of operation decals, load diagrams and safety decals, most of them to
be applied to the vehicle body during installation. These decals must be kept clean and legible at all times, and replaced whenever
required. See also section 10 from page 69 onwards.

with the body / tail lift. Failure to abide by these instructions can result in
material damage, serious bodily injury or death to the operator or bystanders.
Prior to releasing the mechanical platform lock (if so equipped) and using the
tail lift, check if the tail lift can be used safely. Take precautions to ensure
your own safety, and the safety of bystanders or other parties in traffic. Clear
the working area of any objects that could potentially impede movement of
the tail lift. Failure to abide by these instructions can result in serious bodily
injury or death to the operator or bystanders.
Inspect the tail lift prior to each use. If any unsafe condition exists or unusual
noises or movements are noticed, DO NOT use the tail lift and contact an
authorized DHOLLANDIA service agent for repair. Please see pre-trip
inspection procedures under 7.7 page 39.
Read and comply with all warning decals, pictograms and instructions affixed to the tail lift. Failure to abide by warnings and
instructions may result in serious bodily injury or death.
The tail lift must not be used if the operator is intoxicated, impaired or distracted in any way. NEVER use a phone or mobile
device when operating the tail lift.
The tail lift shall be used by means of original control units only. Operating the tail lift with unauthorized control units will
increase risk of serious bodily injury or death to the operator or any bystanders.
Limit the operation of the tail lift to one single operator. Operation of the tail lift by more than one operator at a time may cause
confusion and increase the risk of serious bodily injury or death.
To prevent people from being hit by the platform, by objects falling off the platform or being caught in pinch points or being
pinched by the moving parts of the tail lift:
Keep visual control over the entire working area of the tail lift and its platform at all times, including the area
DIRECTLY BEHIND and UNDER the platform.
DO NOT allow any other person, to stand in the proximity of the tail lift and its platform. ENSURE AT ALL TIMES
THAT NOBODY STANDS UNDER OR WITHIN REACH OF THE MOVING PLATFORM.
When unloading from the vehicle body to the platform,
ALWAYS push the load out, to prevent the load from hitting
you. NEVER pull the load from the vehicle onto the
platform. Pulling the load from the vehicle can result in a
fall from the platform causing serious injury or death.
If pushed out too far, the load can fall off the platform, and
cause serious bodily injury or death to other people.
Deploy the roll stops before pushing out the load. If not
available, push the load slowly while checking the
outboard platform edges.
27 DHOLLANDIA
WARNING
The load must ALWAYS be secured when raising or
lowering on the tail lift, to prevent it from shifting position
and rolling off the platform edges. Failure to properly
secure the load will increase the risk of serious bodily injury
or death to the operator or any bystanders.
When using a pallet jack, lower and rest the pallet or load
upon the platform surface before operating the tail lift.
For loads on wheels, engage the wheel brakes of carts,
trolleys and machinery (if available) before operating the
tail lift.
For loads that could slip, the use of original DHOLLANDIA roll stops, retention ramp(s) or an appropriate alternative
securement device (ex. ratchet straps) is required. The load must not be able to move during movement of the platform. See
9.8 from page 65 onwards for correct use of original DHOLLANDIA roll stops and retention ramp(s).
NEVER leave the tail lift unattended in open position. Before leaving the vehicle unattended, close the doors of the vehicle,
stow the platform in its travel position and switch OFF the main battery disconnect switch in the external control box (if so
equipped), or the cab switch. Leaving the tail lift in open position unattended can result in serious bodily injury or death to
unaware bystanders. See 9.5 - 9.7 from page 53 onwards for instructions on properly stowing platform into its travel position.
Unless this instruction could cause other important risks, NEVER move the vehicle with the tail lift in the open position.
ALWAYS close and secure the doors of the vehicle, stow the tail lift in its travel position and switch OFF the main battery
disconnect switch in the external control box (if so equipped), or the cab switch, before moving the vehicle. If so equipped,
close the mechanical platform lock after stowing the platform in its travel position. Failure to properly stow the tail lift in its
travel position prior to moving the vehicle may result in serious bodily injury or death.
Exception: marshalling manoeuvres to reverse a vehicle into a loading dock or drive off, are excluded from aforementioned
prohibition. It is strongly recommended that fleet operators execute site-specific risk analysis, and provide instructions to their
drivers accordingly. When accepted by your Health & Safety management for specific sites or applications, driving manoeuvres
with open platform must be supervised by a banksman, or controlled by other means such as a reverse camera and sensor
system.
Use of the tail lift near vehicular traffic may result in serious bodily injury or death from being struck by another vehicle. When
operating the tail lift on or near a street or parking lot, be sure to stay clear of vehicular traffic. ALWAYS be sure to clearly
identify to other drivers that the tail lift is in use. DHOLLANDIA recommends use of warning cones to clearly identify to drivers
that the tail lift is being operated. When the tail lift is operated near vehicular traffic, wear working clothes in high-visibility
colours and a retro-reflective safety vest.
DO NOT raise the tail lift with the rear doors partially open. Doing so may damage the doors or the tail lift platform and may
also result in serious bodily injury or death to the operator or any bystanders.
Above all, USE GOOD COMMON SENSE when operating the tail lift. DO NOT operate the tail lift until the contents of this
manual have been read and fully understood. Improper use of the tail lift increases the risk of serious bodily injury or death to
the operator and any bystanders.
NOTICE
The safety instructions in this manual are drawn up with an average, common use of the tail lift in mind.
For specific applications or work conditions, other instructions might be appropriate to reach a higher level of safety. If contra-
indications exist, a formal risk analysis must be performed by the clients health and safety management and safe work
procedures for the drivers and operators must be issued.

7.3 DANGER ZONES, RISK OF CRUSH AND SHEAR INJURY
There are 4 main danger zones on and around the platform, that can be hazardous to the operator and any other persons nearby:
1. ALWAYS stay clear of the range of motion
of the platform.
2. Beware of crushing zone between lowering
platform and ground.
WARNING
Impact by the platform or the moving parts
of the tail lift will result in serious bodily
injury or death. To prevent people from
being hit by the platform, by objects falling
off the platform or being caught in pinch
points or being pinched by the moving parts
of the tail lift:
Keep visual control over the entire
working area of the tail lift at all times,
including the area directly behind and
under the platform;
DO NOT allow any other person to
stand near the tail lift and its platform.
Ensure at all times that nobody stands
under, or within reach of the moving
platform and its load.
WARNING
Lowering an empty or fully loaded platform
on ones feet may result in serious bodily
injury. To prevent people from having their
feet crushed or sheared by the lowering
platform:
Keep visual control over the entire
working area of the tail lift at all times,
including the area directly behind and
under the platform;
When operating the tail lift from a
position on the ground, ALWAYS
stand at the side of vehicle body, at a
safe distance of minimum 50 cm away
from the moving platform.
Correct operator position
Danger zone
29 DHOLLANDIA
3. Beware of the crushing zone between
rising platform and vehicle floor.
4. Beware of the crushing zone between
closing platform and rear frame of vehicle
body.
WARNING
If the operator on the platform stands to
close to the inboard platform edge,
protruding toes might be crushed or
sheared between the rising platform
and the cylinder beam or vehicle floor.
This can cause serious bodily injury.
Therefore, when operating the tail lift
from a position on the platform,
ALWAYS stand at a safe distance of
min. 25 cm from the inboard platform
edge.
NEVER reach over or through the
platform and the moving parts of the tail
lift while trying to operate the lift.
ALWAYS keep your head, limbs and
body clear of the moving platform and
other pinch points.
WARNING
If the operator enters the zone
between the closing platform and the
lift columns with his head, upper body
or limbs, protruding body parts may be
hit, crushed or sheared by the closing
platform. This will cause serious bodily
injury or death.
Therefore, while stowing the platform
in its travel position, ALWAYS stand
with both feet on the ground on a free-
standing, safe operator position at the
side of the body and ALWAYS keep
head, limbs and upper body clear of
hazardous space between the platform
and the lift columns.
NEVER reach over or through the
platform and the moving parts of the
tail lift while trying to operate the lift.
ALWAYS keep your head, limbs and
body clear of the moving platform and
other pinch points.
30 DHOLLANDIA
In case of platforms equipped with manual closure and automatically folding guard rails (sides only), or gas-bottle execution (sides +
rear), make sure you use the grab handle on the guard rail to open and close the platform.
Most column lifts are equipped with a device that
shut closes the platform tight against the lift
columns, after it was tilted in the vertical position
and while it is lifted in its travel position.
Therefore, the operator MUST stand on the side of
the platform and keep head, limbs and upper body
clear of hazardous space between the platform
and the lift columns, while stowing the platform in
its travel position.
WARNING
The operator or other persons approaching too close to these danger zones risk serious bodily injury or death
by pinching, crushing or shearing of limbs, upper body or head. To prevent these hazards:
ALWAYS stand clear of the range of motion of the platform and moving parts of the tail lift;
Keep hands, feet and upper body clear of pinch points and moving parts of the tail lift;
DO NOT allow any other person to stand near the tail lift and its platform.
WARNING
Opening and closing of the platform by holding
the steel members of automatically folding
guard rails can crush the operators hands
between the moving elements of the guard rail.
To avoid bodily injury, always use the grab
handle to manually open or close the platform
and its guard rails, and beware of pinch points
at all times.
31 DHOLLANDIA
7.4 ADDITIONAL RISKS OF LIFTING ABOVE THE VEHICLE FLOOR LEVEL
The tail lifts capacity to travel above the cylinder beam and vehicle floor level can cause additional risks that must be taken into
account by the operator while using the tail lift. ALWAYS pay special attention to the following issues.
7.4.1 Risk of falling
K9 models usually travel up to a much higher distance above the ground than conventional tail lift. The potential consequences of
an accidental fall aggravate with the increased lifting height. Falling from heights can cause serious bodily injury or death.
Tail lifts lifting higher than 2 m above the ground MUST be equipped with guard rails along the exposed edges of the platform. For
tail lifts with a lower range, DHOLLANDIA still recommends that guard rails be used to mitigate the risk of falling.
Guard rails may be purchased along with your tail lift at the initial order, or may be purchased and retrofitted to your tail lift later.
Please see www.dhollandia.com for further information or contact your national DHOLLANDIA distributor. See page 3 for contact
info.
7.4.2 Risk of other persons standing under the platform
K9 models usually travel up to a much higher distance above the ground than conventional tail lifts. Therefore, there is a greater
risk that somebody could stand below the platform while the platform is situated high above the ground. Lowering the platform
onto a person will cause serious bodily injury or death.
Tail lifts lifting higher than 2 m above the ground MUST be equipped with a sound alarm, activated whenever the platform is
lowered.
WARNING
Falling from heights can cause serious bodily injury or death.
To prevent injury or death by falling from the platform:
ALWAYS make sure your footing in solid;
ALWAYS hold onto the guard rails;
ALWAYS maintain 3 points of contact.
WARNING
If platform is lowered onto a person, this will cause
serious bodily injury or death.
To prevent bodily injury or death by a platform lowering
onto a person:
NEVER allow any other person to come near the
working area of the tail lift and its platform;
ALWAYS keep visual control over the entire
working area of the tail lift and its platform;
For internal platforms, NEVER allow any other
person inside the vehicle body when using the tail
lift.
Before lowering, ALWAYS inspect the area
UNDER and BEHIND the platform.
32 DHOLLANDIA
7.4.3 Risk of crushing and shearing
For all brands and types of tail lifts, there is risks of crushing and shearing
toes and feet between:
1. the rising platform and the vehicle floor (see 1 on right side),
2. or between the lowering platform and the ground (see 2 on right side).
The operator must ALWAYS stand on a safe operator position while using
the tail lift. See also 7.3 from page 28 onwards and 7.5 from page 33
onwards.
Additional risk exists on K9 models for any person standing inside the
vehicle body, or present in the scissor zone between the moving platform
and the vehicle floor.
Any person caught and crushed between the moving platform and the
vehicle floor will suffer seriously injury or death (see 3 below).
Any person standing inside the vehicle body, with feet protruding beyond
the outboard edge of the vehicle floor, will suffer severe crushing and
shearing of his feet or toes by a platform travelling down from a higher
position. This can result in serious bodily injury (see 4 on right side and
below).
WARNING
Any person standing on the platform or inside the vehicle body, too close to the inboard platform edge, risks
being crushed or sheared between the moving platform and the vehicle floor. This can result in serious
bodily injury or death.
To prevent injury or death by crushing or shearing:
When standing on the platform, ALWAYS stand at a safe distance of min. 25 cm from the inboard
platform edge;
When standing inside the vehicle body, ALWAYS stand at a safe distance of min. 25 cm from the
outboard edge of the vehicle floor;
NEVER step in or out of the vehicle body while the platform is in motion.
Before moving the platform, ALWAYS inspect the area UNDER and AROUND the platform.

7.5 SAFE OPERATOR POSITION
The instructions on safe operator position aim to enforce that the
operator stands in a safe position before and while operating the tail lift,
and protect him against the risks of crushing and sheering as described
in 7.3 7.4.3 from page 28 onwards.
Main external control box: the zone just in front of the side-mounted
external control box, is the only position from where the operator can
safely OPEN and CLOSE the platform. It is also safe to LOWER and
LIFT the platform from this position. In case of optional hydraulic
closure, the main external control box is equipped with 2-hand
operation.
Auxiliary controls: the operator may also lower and lift the platform
through use of the auxiliary controls. The operator must use extreme
caution when lowering or lifting the platform with the auxiliary controls
and must ensure it is done from a safe position. Use of auxiliary controls
from an improper position greatly increases the operator's risk of
crushing or shearing of toes, limbs, head, and upper body as well as
death. See 7.3 - 7.5 from page 28 onwards regarding Danger zones,
risk of crush and shear injury.
Handheld auxiliary controls with a spiral cable should only be used under the following conditions (1):
(1) Remark: The CE standard EN1756-1 suggests a number of other, less usual solutions providing sufficient protection against crushing and
sheering of the toes and feet, such as a hinged foot protector or cut-out switch. Consult the latest edition of DHOLLANDIAs fitting instructions FIT-
ELEC-OPTION or contact your national DHOLLANDIA dealer for more information. See page 3 for contact info.

marked at a minimum of 25 cm from the hazard zone
between the platform and the rear of the vehicle floor
(see 3 in 7.3). A fixed internal control should NEVER be
used from a position on the platform.
The marked operator positions on the platform must be
kept clear at all times. It is prohibited to place a load on
these dedicated areas.
In case of a main external control box with 2-hand
operation, the power to any of the auxiliary controls must
be connected to and dependent upon the safety switch
in the main external control box. Activation of the
auxiliary controls must deactivate the functions on the
external control box.
It is prohibited to bypass or modify any of the safety features of the tail lift. If activation of the external control box does not
deactivate auxiliary controls, stop using the tail lift, and contact an authorized DHOLLANDIA agent to rectify.

7.6 INSTRUCTIONS FOR WORKING AT LOADING DOCKS
There are 3 main ways of handling a column lift at the loading docks: Restrictions and precautions do apply. See below.
1. Platform lowered below the vehicle floor level. All cargo is loaded / unloaded over a dock plate that links the dock and the vehicle floor.
2. Platform is used as a loading platform; or as a bridge plate (in case of optional tilt cylinders).
3. Platform is hidden in a pocket or briefcase under the loading dock. All cargo is loaded / unloaded over a dock plate that links the dock and the vehicle floor.
1. When the intention is to dock with the platform lowered below the vehicle floor level, DO NOT lower the platform until the vehicle
is standing on flat even ground. ALWAYS revers slowly, and make sure you maintain sufficient ground clearance between the
lowest part of the tail lift and the ground. Take into account variations in the suspension and vehicle height.
WARNING
Improper use of the tail lift may result in damage, premature wear or failure of the tail lift, and will increase the risk of serious
injury or death to the operator and other persons nearby.
In order to maximize the durability, ensure long-term reliability of the tail lift, and protect operators and bystanders from serious
bodily injury or death, the operator must comply with the loading instructions and safe working procedures below.
NOTICE
When reversing a vehicle with column lift into a loading dock, ALWAYS make sure there is sufficient ground clearance between
the lowest part of the tail lift and the ground.
ALWAYS reverse slowly, and avoid hard dock impact on the tail lift.
Reversing with insufficient ground clearance, or with too hard dock impact may result in severe damage to the tail lift.
Min. 15 cm
37 DHOLLANDIA
2. When the intention is to use the platform as a loading platform or bridge plate, the following instructions apply:
The tail lift can only be used as a loading platform if the dock is lower than the vehicle floor.
Unless the vehicle suspension can be blocked and the floor maintained at the original vfh, the max. load transferred over the platform should not exceed 1100 lbs / 500 kg. Exception: column lifts with 2 tilt cylinders [option OVH011].
The tail lift can be used as a bridge plate, if it is equipped with the optional tilt cylinders with adjustable platform orientation [option OVH011].
It is forbidden to drive forklifts or heavy electric pallet jacks over the platform.
The total weight of the load and the lifting device must not exceed the maximum rated capacity of the tail lift. Beware not to overload!
A minimum section of 15 cm of the outboard platform edge must rest on the loading dock.
While loading or unloading, the loading floor of the vehicle might lower or rise relative to the loading dock. Use the electrical controls to adjust the platform position flush with the loading dock surface.
NEVER use a foldable platform as a bridge plate between the vehicle floor and a loading dock.
NEVER use a dock plate on top of a floating platform as a bridge plate between the loading dock and the vehicle floor.
OVERLOAD
Min. 15 cm
38 DHOLLANDIA
3. When the intention is to stow the platform in a pocket or
brief case under the loading dock, observe following
points before reversing into the dock:
Make sure the pocket is deep enough for the depth of the
platform.
Make sure there is sufficient clearance above and below
the platform, taking into account all possible variations in
vehicle suspension and vehicle floor height.
Make sure the platform does not touch the ceiling,
ground or end wall of the pocket.
Whenever cargo is loaded or offloaded with forklifts, electric pallet jacks, and the total weight of the load plus handling
equipment exceeds the maximum rated capacity of the tail lift, ALWAYS use a dock plate from the loading dock to the
vehicle floor, and safely stow the lift below the vehicle floor level, or in the pocket or brief case under the loading dock.
WARNING
ALWAYS stand with both feet on the
ground on safe operator position at
the side of the body when operating
the external control box (see also 7.5
from page 33 onwards) or the platform
locks. NEVER operate the external
control box or the platform locks from
an elevated position, such as the
platform or a loading dock.

7.7 RECOMMENDED DAILY PRE-TRIP INSPECTION
Before operating the tail lift, the operator must conduct the following daily pre-trip inspection. Use caution: stay clear of the
area directly behind the platform while conducting the daily pre-trip inspection.
Replace missing, worn or illegible warning decals immediately. See page 3 for contact info.
Make sure the cabin switch and / or main battery disconnect switch in the control box switch on and off accordingly.
Make sure the battery is fully charged, the main fuse is in good condition, and battery terminal connections are corrosion-free and
tight.
Check the overall condition of the main external control box and its switches. Confirm that all switches (except the ON / OFF cabin
switch) swiftly return to the neutral position after releasing them.
Check the overall condition of the cables entering the various control units, and of the cables to the pump unit. Make sure cables
are not chafed, loose or damaged.
Ensure the cover of the pump unit is properly installed and secured.
Check the pump unit for visible oil leaks.
Check if the platform is standing tight and straight between the columns (no cables, chains or pulleys damaged).
Follow the instructions in section 9 from page 45 onwards to open and lower the platform to the ground, and continue the
checks:
Visually inspect the general condition of the lift frame, lift runners, the mounting bolts or welds to the rear frame of the vehicle
body, and diagonal braces supporting the underside of the columns. Look for cracks or deformation in the material and welds.
Make sure the bolts of the columns to the rear frame are tightened.
Visually inspect columns and lift runners. Visually inspect that the chains or cables are under tension and the platform hangs level
with the vehicle floor. Make sure the inside of the columns is free of sand, dirt or debris.
Make sure all pivot pins are properly locked and secured.
Visually inspect the general condition of the platform and the stow lock. Look for cracks or deformation in the material and welds.
If so equipped, make sure the platform-mounted options function correctly (roll stops, retention ramps, flashing warning lights).
For lifts with manual closure: check the operation and overall condition of the platform lock. After lowering the platform down from
its travel position, it should not be possible to pull the platform open by more than 10 without disengaging the platform lock.
For lifts with manual closure: Check the operation and overall condition of the torsion bars. The platform can be manually opened
and closed without excessive effort.
WARNING
Using a tail lift that is damaged or improperly serviced can put the operator and bystanders at great risk of serious bodily injury
and death.
To avoid this risk, inspect the tail lift prior to the first use of each day. Ensure that all safety systems and all functions operate
correctly, and that no maintenance or repair is required.
If any unsafe condition exists or unusual noises or movements are noticed, DO NOT use the tail lift, and contact an authorized
DHOLLANDIA agent for immediate repair [see Notice].
DO NOT cover up any accidents or damage; it can be dangerous to you, your co-workers, and other persons.
NOTICE

Check the general condition and operation of the guard rails. Look for cracks or deformation in the material and welds. Ensure
they remain locked in the raised position after deployment.
Check the overall condition of the auxiliary controls and their switches. Confirm that all switches swiftly return to the neutral position
after releasing them. In case of a handheld control with spiral cable, inspect the spiral cable for wear or damage.
Make sure safe operator position and centre point of maximum load are clearly marked on the platform.
Make sure the platform surface is clean and can be accessed safely. Remove any snow, mud, dirt, debris, or slippery liquids.
Make sure you wear safety-toe shoes with a good non-slip sole.
Check the cylinder beam and optional tilt cylinders, their safety valves and fittings for visible oil leaks. Follow the hydraulic pipes
and fittings to the pump unit. Make sure all wires and hydraulic pipes are undamaged, not pinched or chafed anywhere, and
adequately secured with cable ties. Check for visible oil leaks.
Perform all movements with an unloaded platform several times with all available control units. Use the operation manual for
guidance.
Make sure all movements occur smoothly and quietly, without jerking motion or unusual noises. During LIFT and CLOSE functions,
only the sound of the electric motor in the pump unit should be audible.
Remember: if any part of the pre-trip inspection reveals a need for service or repair
DO NOT use the tail lift until it has been serviced or repaired by a qualified service technician.
Switch OFF power at the main battery disconnect switch or cabin switch [see 9.4 on page 52].

7.8 IMPORTANCE OF PREVENTATIVE MAINTENANCE
If a tail lift cannot be repaired immediately in case of breakdown, it must be put out of operation and secured against unauthorized
use.
A tail lift put into its travel position with the help of external devices (forklift, gantry crane, etc.), is not supported by its hydraulic
cylinders. After releasing the mechanical platform lock, the platform and lifting mechanism will drop in free fall, without any
possibility to stop the fall by means of the regular controls.
Note: examples of additional means are additional securing of the platform lock (if available), or securing the platform by means
of ratchet straps, hoists, etc.
To re-open the tail lift, use again an external device (forklift, gantry crane, etc.) for additional support. Or repair the breakdown
first, bring the hydraulic system under pressure, and release the platform locks after satisfactory testing of the hydraulic integrity.
Follow the MAINTENANCE AND REPAIR MANUAL for all maintenance and repair works.
NOTICE
Competent and regular preventative maintenance is essential to the operational reliability of the tail lift as well as the safety of
the operator and all bystanders.
All maintenance and repair work must be performed by authorized DHOLLANDIA service agents, and using original
DHOLLANDIA replacement parts only.
Please consult the separate MAINTENANCE AND REPAIR MANUAL for specific instructions regarding periodic maintenance.
WARNING
Impact by a falling platform will result in serious bodily injury or death. To reduce the risk of injury:
Close the platform lock (if available), and apply additional means to immobilize the platform [see note
below].
Attach a clear and highly visible warning tag to the platform and the external control box.
Warn your supervisor and have this vehicle put out of service.
Contact an authorized DHOLLANDIA service agent to repair the tail lift prior to any further use.
42 DHOLLANDIA
8 LOAD CHARTS AND CORRECT LOADING PROCEDURES
NOTICE
Tail lifts are NOTdesigned to LIFT / LOWER weights corresponding to their maximum rated capacity over the entire surface
of the platform. The maximum rated capacity is valid at a certain distance or centre point of maximum load behind the vehicle
body. Behind that point marked on the platform, the maximum safe working load diminishes according to the load charts below.
When LIFTING, the tail lift is normally protected against overload by the pressure relief valve in the hydraulic circuit. Most of
overload events and resulting damage happen when LOWERING loads.
WARNING
Overloading and improper loading and unloading of the tail lift will put the operator and bystanders at great risk of serious bodily
injury or death. Such conditions will also cause premature wear and damage to the tail lift, or failure of the tail lift.
Therefore, it is essential that the operator respects the maximum rated capacity and follows the loading instructions and the
load chart with great care.
DHOLLANDIA disclaims liability for all personal bodily injury and / or property damage that results from overloading practices.
The maximum rated capacity is the maximum weight that the tail lift can carry under the following best possible circumstances:
the centre of gravity of the load stands no further than the designated centre point of maximum load of the tail lift, marked
on the platform surface, and
the load stands mid-point between the lift arms, and is at equal distance from both platform sides.
NOT OK NEVER
position the load at the outboard
platform edge.
OK ALWAYS
position the load as close as possible to the
rear of the vehicle, near the
inboard platform edge.
Uneven loading on one side of the platform should be avoided. Limit the load to 50% of the maximum rated capacity when loading on one side of the platform only.
NOT OK NEVER load on one side of the platform only. Or limit load to 50% of maximum rated capacity.
OK ALWAYS position the load mid-point between the lift arms.
43 DHOLLANDIA
The maximum safe working load GOES DOWN according to the load charts. The following type of load chart decals are supplied
with the tail lift, and must be duly observed.
WARNING
Overloading and improper loading and unloading of the tail lift will put the operator and bystanders at great risk of serious bodily
injury or death. Such conditions will also cause premature wear and damage to the tail lift, or failure of the tail lift.
Pay attention to avoid concealed overload situations as shown in examples below. Serious bodily injury or death may result
from failure to abide by these warnings.
EXAMPLE
EXAMPLE
NEVER let the load extend beyond
the outboard edge or side edges of
the platform.
NEVER let the wheels of a pallet jack extend or drop down beyond the outboard
or side edges of the platform. Keep the pallet jack and its load on the platform
surface, as close as possible to the inboard platform edge. Lower and rest the
pallet or load on the platform surface to prevent it from shifting position while
lifting and lowering.
OVERLOAD OVERLOAD
44 DHOLLANDIA
WARNING
Lower and rest the pallet or load on the platform surface
to prevent it from shifting position while lifting and
lowering.
NEVER drop any load on the platform (ex. by means of
a forklift, gantry crane, etc). The impact of dropping a
load is far greater than the nominal weight of the load
and can cause severe damage to the tail lift.
NEVER drive a forklift onto the platform. Driving a forklift onto the platform can cause severe structural damage, potentially
invisible to the operator at first glance. Further use of an overloaded or damaged platform can put the operator and bystanders
at great risk of serious bodily injury and death.
NEVER try to scoop loose material (ex.
sand, gravel, rocks, etc) from the
ground, to attempt to move it by means of
the platform, or to lift / lower it on the
platform.
NEVER use the platform to level the
ground surface, or to push or pull loads or
material by means of the platform. NEVER
use the platform to move snow or other
debris.

9 OPERATING INSTRUCTIONS PRINCIPLES AND PROCEDURES
9.1 PLATFORM RIDE
The ride of a tail lift describes the movement that its platform goes through when lifting and lowering. All column lifts in this manual
are equipped with a flat platform and a level ride.
While the platform travels up and down, the angle between the platform and the columns remains unchanged. If the vehicle is
standing level on flat, even ground, the platform will travel up and down level with the ground.
The majority of column lifts have manual closure. In option, certain models can be equipped with 1 or 2 tilt cylinders.
Option OVH004 (= 1 tilt cylinder) enables the operator to open and close the platform hydraulically instead of manually, but the
orientation of the platform is not adjustable. (Platform is fully closed at 90 or fully open at 0).
Option OVH011 (= 2 tilt cylinders) enables the operator to open and close the platform hydraulically instead of manually, and to
adjust the orientation of the platform to the slope of the ground, or to tilt the platform towards a loading dock.

WARNING
It is important for both types of tail lifts that loads on wheels, or loads that could easily shift position and fall from the platform,
are properly secured on the platform surface prior to operating the tail lift. See also 9.8 from page 65 onwards.
For lifts with non-adjustable platform orientation, it is ESSENTIAL that the operator ensures that roll stops or retention ramps
are deployed (if available), wheel stops or brakes are activated, or the load is secured on the platform in a different way prior
to operating the tail lift.
Improperly secured loads could fall off the platform, and put the operator and bystanders at great risk of serious bodily injury
and death.

9.8 THE USE OF ROLL STOPS
WARNING
If the load is not properly secured on the platform while lifting or lowering, it could shift position, destabilize the operator riding
on the platform, and cause him / her to fall. Or the load could fall off the edge, and hit the operator or bystanders.
Improperly secured cargo can put the operator and any bystanders at great risk of serious bodily injury and death.
Therefore, all cargo must be properly secured on the platform, before lifting or lowering.
Before lifting or lowering loads, ALWAYS apply all brakes
or stops available to secure the load. Engage the wheel
brakes of carts, trolleys or machinery (if available). When
using pallet jacks, lower and rest the pallet or load onto
the platform surface.
