6.3 GETTING STARTED

OEM Vehicle manufacturers may have issued important instructions on various aspects of the tail lift installation, specific to the

brand and type of chassis, such as welding instructions (or prohibition to weld!); instructions on chassis drilling and bolt-on

connections to the chassis; recommendations on the use of hydraulic stabilizing legs; guidelines for the battery and ground cable

connections; fuses and other electrical interfaces; etc...

NOTICE

The installer MUST verify and ensure compatibility between the tail lift and the vehicle.

The installer MUST verify and ensure compliance with the installation instructions issued by the vehicle and body

manufacturer.

Improper modifications to the vehicle chassis or body could cause serious mechanical failure of the vehicle. The installer MUST

ensure that modifications to the vehicle chassis and / or body will not adversely affect the structural integrity of the chassis and

/ or body.

In the event instructions of vehicle manufacturer conflict with the installation instructions issued by DHOLLANDIA (e.g. on fuse

ratings, etc.), contact your national DHOLLANDIA distributor for further assistance.

In the event OEM instructions conflict with the installation instructions issued by DHOLLANDIA (e.g. fuse ratings, etc.) contact

DHOLLANDIA (see page 4 for contact details).

Place vehicle on a flat even ground and chock the wheels so that it cannot move during the installation process. In case of a motor

vehicle, switch off the engine and engage the parking brake before starting.

Verify the installation kit is complete, and that all parts needed to correctly fit the tail lift are present.

Compare the voltage of the vehicle batteries with the voltage of the hydraulic pump unit of the tail lift.

Compare the installation dimensions and maximum installation parameters indicated in the installation drawing with the actual

dimensions of the vehicle, to verify compliance. (See next chapter).

Verify if the vehicle chassis and body are strong enough to support the load and moment created by the tail lift at maximum rated

capacity. Refer to the Body Builder Guidelines of the OEM vehicle manufacturer for details.

Check the stability of the vehicle and the weight over the axles with the addition of a tail lift loaded to maximum capacity. The

weights indicated in the technical documentation and price list are theoretical and approximate and may vary from one tail lift

installation to another.

Make sure that the body is accurately fitted to the vehicle chassis.

Remove all objects that are mounted in the mounting space required by the tail lift (RUP, spare wheel carrier, pallet racks, tool

boxes, etc.). If necessary, consult with the OEM vehicle manufacturer for replacement solutions (e.g. special spare wheel carriers,

exhaust pipe modifications, etc.).

Finish the tail lift in compliance with applicable road legislation of the country where the vehicle will be registered.

When connecting hydraulic fittings, make sure that the connections are thoroughly clean, and that you dont contaminate the

hydraulic oil.

Grease all bearings and pins before putting the tail lift into service. It is recommended to grease all articulation bearings before

mounting the corresponding articulation pin.

After installation, work through the pre-delivery inspection (PDI) checklist, verify all check points with due diligence. Make sure the

final inspection is signed off by an inspector who is not part of the installation team.

14 DHOLLANDIA

Do not pressurize any tail lift functions (LIFT / LOWER) before the tail lift installation is fully finished.

During installation and while testing, verify that the tail lift and its moving parts dont interfere with, or cause damage to the vehicle

systems (e.g. to suspension, braking system, hydraulic and electrical circuits, etc.).

When jacking up the lift frame, push from the centreline of the lift frame. DO NOT apply force at either end of the lift frame to

change or correct the mounting height at one side only.

Ensure that the platform is centred in the centreline of the vehicle, and that it is flush and parallel with the extension plate.

Secure the correct platform position by clamping the platform main section to the 76mm mounting tubes. [Figure 9.5]

Figure 9.5

WARNING

The platform and attached lift frame are very heavy! When falling on a person, they can cause serious personal injury or death.

Therefore, handle the platform and attached lift frame with great care. Use hoists and a gantry crane to raise the platform and

attached lift frame in their correct mounting position.

Place C-clamps on each side of the platform to prevent the hoist chain from slipping off the platform.

25 DHOLLANDIA

If required, tilt the lift frame relative to the vehicle chassis, to ensure that the top surface of the lift frame is parallel to the vehicle

floor. A torpedo level is commonly used to ensure the alignment of the lift frame and vehicle floor. If convenient, the piston-rod

ends of the lift cylinders may be disconnected so that the lift arms and lift frame can move freely. [Figure 9.6]

Figure 9.6

NOTICE

Ensure the platform and lift frame are positioned in conformance with the mounting instructions and dimensions indicated in the

installation drawing and manual, before drilling or welding the mounting plates to the chassis.

It is not allowed to reduce the width of the mounting plates without prior written authorization from DHOLLANDIA.

10 FIXATION OF THE BOLT-ON MOUNTING PLATES

The mounting plates are designed as a bolt-on system, both where they mount to the lift frame, and where they mount to the

vehicle chassis.

If you intend to weld, beware of precautions below:

NOTICE WARNING

The tail lift might be equipped with thermoplastic hydraulic pipes, that can be easily damaged by welding. Damage to a pipe

can lead to sudden pressure loss, and accidental drop of the platform.

Welding sparks and slag penetrating hydraulic pipes under pressure, could cause a flaming flash, and serious personal injury

to the welder and any bystanders.

To avoid risk of serious personal injury, ALWAYS use adequate coverage (e.g. by a leather welding blanket) to shield the

thermoplastic pipes whenever welding is done on or near the tail lift.

CAUTION

Before welding, note that welding on galvanized parts releases hazardous fumes. Provide adequate

ventilation, and wear an appropriate toxic fume rated welding respirator

It is strongly recommended to first grind off the galvanizing in areas where welding is to be done.

26 DHOLLANDIA

NOTICE

Some OEM vehicle manufacturers prohibit welding on the vehicle chassis.

Verify the body builder guidelines issued by the OEM vehicle manufacturer, and make sure you comply.

Figure 10.1

See [Figure 9.2] on page 22 for initial positioning of the mounting plates.

Slide the mounting plates sideways until they are perfectly aligned with the chassis rails. [Figure 10.1]

Straighten the mounting plates, and make sure they stand perpendicular to the lift frame. Ensure the lift frame is correctly centred

under the vehicle chassis and body. [Figure 10.1]

The mounting plates MUST be bolted to the lift frame according to the instructions in [Figure 10.2]. Tighten the

bolts and nuts with the prescribed torque.

27 DHOLLANDIA

Figure 10.2

The mounting plates MUST be bolted to the vehicle chassis, the bolts and nuts tightened with the required torque, according to

the instructions below and to the right.

Pay special attention to the type, minimum quantity, minimum size and strength, position and prescribed torque. [ Figure 10.3]

Per side

4x M24x2 (8.8) 195Nm

28 DHOLLANDIA

The mounting plates are bolted to the vehicle chassis with min. 6 bolts M14 per side, supplied with the lift, spread over the widest

possible surface to maximize the strength of the bolted connection. Fasten the 6 bolts M14 per side with the required torque.

[ Figure 10.3]

Figure 10.3

Figure 10.4

WARNING

Incorrect installation of the mounting plates and bolts can lead to accidental fall of the tail lift off the vehicle chassis.

A fall of the tail lift off the chassis can damage the tail lift and / or vehicle chassis and can cause serious bodily injury or death

to the operator and any bystanders.

Therefore, it is essential that the mounting plates are installed following the instructions of this manual.

Per side

Min. 6x M14 (10.9) 185 Nm

Extra 2x M14 (10.9) 185 Nm

Check if the long sills, the body cross members and

floor are securely attached to the chassis and will form

one solid construction once weight will be applied on

the platform. If not, attach the mounting plates of the

tail lift to the long sills on top of the chassis by means

of 2 additional bolts M14 per side, or equivalent.

[Figure 10.4]. Fasten these bolts with the required

torque.

29 DHOLLANDIA

Figure 10.5

Alternatively, the mounting plates may be welded to the chassis rails instead of bolted. When doing so, observe the precautions

regarding welding on galvanized steel on page 25.

Make min. 6 pcs. 10mm welds, min. 102mm long, evenly spread around the periphery of the mounting plates (per plate). [

Figure 10.5].

When there is an overlap between the mounting plates and the long sills, make min. 2 pcs. 10mm welds, min. 102mm long, at the

top of the mounting plates (per plate). [Figure 10.5]

If there is no overlap, add a connection plate to extend the height of the mounting plate, overlap the long sills, and make min. 2

pcs. 10mm welds, min. 102mm long, at the top of the mounting plates (per plate). Apply equivalent welds to join the mounting

plate with the connection plate. [Figure 10.6]

WARNING

During installation, the bolts and nuts should be fastened to the proper torque, shown in these installation instructions.

If you use mounting bolts not supplied by DHOLLANDIA, make sure the total strength is at least equivalent as per this manual.

Check and retighten the bolts after static and dynamic load tests performed at the end of the installation process.

30 DHOLLANDIA

Figure 10.6

Min. 6x M14 (10.9) 185 Nm

Depending on options chosen, the mounting plates can be foreseen with sleeve holes, to avoid that plates must be drilled during

installation, and allow for easy adjustment of the position of the lift frame. [Figure 10.6]

If the vehicle chassis is high enough to use all 3 lines of prepunched holes, spread bolts around the contour of the mounting plates

as shown [Figure 10.6].

To avoid movement of the lift frame by impact during use (e.g. at the loading dock), and firmly secure the positino of the lift frame

on the chassis, min. one of the M14 bolts should be mounted in a round hole. [see 1 in Figure 10.6].

If the vehicle chassis is not high enough to use all 3 lines of pre-punched holes, drill additional hole(s) in the chassis to maximize

the vertical distance between the bolts, and obtain widest possible spread of mounting bolts over the available surface.

[see 2 in Figure 10.6].

Further, all points in section 12 above apply to any mounting situation with sleeve holes.

11 INSTALLATION OF CONTROL SWITCH

31 DHOLLANDIA

11.1 MOUNTING OF THE CONTROL SWITCH

Mount the toggle switch in a position that allows the operator to work from a safe standing area at the side of the tail lift,

outside reach of the platform and other moving parts of the lift.

Mount it in a location that is accessible from the ground and the vehicle floor level.

NOTICE

In order to avoid water ingress and electrical malfunction, NEVER mount the toggle switch facing upward. [Figure 11.2]

Measure the holes on the control unit itself or use the template [Figure 11.1] to drill the screw holes, and the passage for the

electrical cable.

Use 6.4mm self-tapping screws to mount the control switch.

Route the electrical cable to the pump unit. Position, fasten and protect it in such a way that it cannot be damaged by the moving

parts of the tail lift or other vehicle components.

Figure 11.1

Feed the electrical cable through the rubber grommet at the rear of the pump unit. Check and make sure the rubber grommet

properly seals and protects the inside of the pump unit, after passing the cable.

Prevent ingress of water into the pump unit and control boxes if applicable [Figure 11.2]:

1. Route and secure cables downward, forming a drip loop as they exit the pump unit. [Figure 11.3]

2. Wrap a zip-tie around the cable before it enters the pump unit or control box. This will help to interrupt the flow of water

into the enclosure.

Connect the wires of the cable to the connection points in the pump unit, as per wiring diagrams attached.

Coil in the excess cable inside the pump unit. Fix and immobilize it with cable ties to the hydraulic return pipe of the valve block.

12 CONNECTION TO THE BATTERIES

A general schematic of how to correctly connect the batteries to the tail lift is provided in Figure 12.1.

Figure 12.1

40 DHOLLANDIA

Refer to the separate manual ELECTRICAL INSTALLATION N-A GENERAL 01 for more detailed information on the

electrical installation, connection to the tail lift or vehicle batteries, installation of fuses or circuit breakers, and ground

connections.

If not supplied with the tail lift, these can be downloaded from the DOWNLOAD section on our website:

http://www.dhollandia.com

Please confirm you have reviewed the most up-to-date version of this manual prior to continuing.

If you want to operate the tail lift before the batteries are installed, use a temporary battery of min. equivalent

power as the final battery, charged by a battery charger connected to a wall plug. [Figure 12.2]

Figure 12.2

NOTICE

NEVER run a tail lift from a battery charger only. This can cause damage to the pump unit and electrical parts of the tail lift.

41 DHOLLANDIA

13 PUTTING THE TAIL LIFT INTO SERVICE

Remove the mounting bar from between the lift arms and the lift frame (used to install lift at pre-defined mounting height MFT).

[Figure 13.1]

Switch on the main electrical power to the tail lift.

Push the LIFT button to pressurize the hydraulic system. Stop when you hear the hydraulic pump turn in overpressure.

Figure 13.1

NOTICE

Check for visible leaks of hydraulic oil as the system is being pressurized. If there is leakage, correct the problem prior to continuing.

WARNING

Improper use of the tail lift will put the operator at great risk of serious bodily injury and death. If in doubt of how to use tail lift

correctly, the installer should consult the operation manual prior to continuing.

Air might be trapped in the hydraulic circuits, as long as the tail lift has not been bled. Air can cause the tail lift to make

unexpected movements and can put the installer at great risk of serious bodily injury. The installer should remain vigilant and

stay out of the range of motion of the platform and the moving parts of the tail lift as long as the hydraulic circuits have not been

purged.

42 DHOLLANDIA

Lower and remove the hydraulic mounting jack.

Remove the C-clamps, chains, hoists and other supports that have been used during installation.

Push the LOWER button to lower the platform to the ground.

Remove the temporary bolts from the auto-tilt brackets L+R. This removal will enable the AUTO-TILT function.

[Figure 13.2]

Test the LIFT and LOWER functions at least 5 times. Look for any interference between the tail lift and the

vehicle. The tail lift should operate smoothly and quietly, at a constant speed.

Only the sound of the pump unit should be audible. In case of jerking movements or odd sounds, you should

investigate and correct to avoid damage to the tail lift or potential hazards for the operators.

Figure 13.2

Bleed all air from the hydraulic circuits. Preferably raise the rear end of the vehicle off the ground or raise the vehicle air suspension

to its allowed maximum. LIFT the platform to vehicle floor level. [Figure 13.3]

Then LOWER the platform fully to its deepest position at the ground, continue to press LOWER for 20 sec. LIFT the platform

again, and repeat until no air bubbles run back to the oil reservoir. [Figure 13.3]

Figure 13.3

The platform opener assembly is pre-installed at the factory but needs fine-tuning during the installation. If removed, mount it back

in its original position to avoid damaging the platform prior to operating the tail lift.

Adjust the length of the platform opener assembly. [Figure 13.4]

It is usually pre-installed at the factory but needs fine-tuning during the installation. If removed, mount it back in its original position

to avoid damaging the platform prior to unfolding and folding the platform.

M

43 DHOLLANDIA

Figure 13.4

CAUTION

If platform opener is mounted too far in, the platform will lean too far back when it is lowered to the ground. The operator can

suffer a back injury when pulling the platform open from this position. [Figure 13.4]

If platform opener is mounted too far out, the platform could fall over when it is lowered to the ground and could hit the limbs of

the operator or any bystanders. [Figure 13.4]

Therefore, it is important that you adjust the platform opener so that the platform stands just inside from vertical position when

lowered to the ground, and the operator can unfold the platform sections comfortably.

44 DHOLLANDIA

14 PLATFORM ORIENTATION

1. LIFT the platform to the floor height. Lay a straight edge lengthwise across the platform. Make sure the flip-over point and

platform main section are even with each other. [Figure 14.1]

2. If needed, adjust the angle between the 2 platform sections by turning the 2 adjuster bolts at the underside of the platform main

section. Loosen the counter nuts, then adjust bolt length, and retighten the counter nuts. [Figure 14.1]. Make sure both sides

are adjusted equally, so that all bolts will support the flip-over point (and its load) evenly.

3. Check and adjust the orientation of the whole platform compared to the extension plate and vehicle floor. Because the tail lift will

decline slightly when loaded, adjust the platform pitch so that the tip is 25.4mm to 50.8mm higher than the extension plate.

[Figure 14.2]

4. Adjust the platform pitch using the 2 adjuster bolts at the inboard edge of the platform main section [dim. Y in Figure 14.2].

Loosen the counter nuts, then adjust the bolt length, and retighten the counter nuts. Make sure both sides are adjusted

equally, so that all bolts will support the platform (and its load) evenly.

WARNING

Failure to adjust the pitch of the flip-over point and complete platform properly, can cause the cargo to fall off the platform during

operation.

Falling cargo will put the operator and any bystanders at serious risk of bodily injury and death.

Therefore, it is important that the pitch of the flip-over point and complete platform are adjusted correctly conform with

instructions in this manual.

15 MOUNTING OF THE SIDE STEPS & DOCK BUMPERS

1. There are 2 possible set-ups [see also drawings in appendix]:

I. Side steps directly bolted to floor extension plate by means of 2 bolts M16 [1 in Figure 15.1], to obtain 2440mm overall

width (for 2130mm platform width).

II. Side steps with intermediate mounting blocks [2 in Figure 15.1], bolted together in 2 subsequent steps by means of 2+2

bolts M16 [1+2 in Figure 15.1] to obtain 2590mm overall width (for 2310mm platform width).

2. Bolt the side steps to the floor extension as shown. If a 2590mm extension kit is specified, install the extension kit [far right in

Figure 15.1] before mounting the side steps.

3. Maintain a 90 angle between the steps and the extension plate. [Figure 15.2]

4. Fasten all bolts and locking nuts to the required torque settings.

Figure 15.1

Figure 15.2

5. Weld the support channels to the rear sill and underside of the I-beam cross members [Figure 15.3]. Weld to as many I-beam or

cross members as possible, to distribute the forces of dock impact as much as possible.

CAUTION

Before welding, note that welding on galvanized parts releases hazardous fumes. Provide adequate

ventilation, and wear an appropriate toxic fume rated welding respirator.

It is strongly recommended to first grind off the galvanizing in areas where welding is to be done.

NOTICE

Where chassis beams, longs sills, the rear sill and other steel chassis or body components have been cut, grinded, drilled, welded

etc, the installer should apply adequate anti-corrosive coating to protect the vehicle and body against corrosion. Check and make

sure you comply with the instructions of the OEM vehicle manufacturer.

16 MOUNTING OF THE OPTIONAL WALK-RAMP KIT OAM054

The optional walk-ramp kit ref. OAM054 is designed to be bolted to the extension plate. It consists of:

1. Walk-ramp carrier assembly [1 in Figure 16.1]

2. 2 pcs. 114mm deep spacer tubes for the dock bumpers [2 in Figure 16.1]

Figure 16.1

The walk ramp carrier assembly consists of:

1. Mounting brackets [A in Figure 16.2], that can be mounted in 2 positions with 25.4mm height difference.

2. Platforms stoppers [B in Figure 16.2], that can be adjusted in height steps of 25.4mm and rotated.

Test mount the walk-ramp carrier assembly to the extension plate at the height that gives the adequate clearance for the walk-

ramp to slide in and out.

LIFT the folded platform into the intended travel position. Adjust the height and orientation of the platform stoppers [B on Figure

16.2], so that they touch and stop the main steel reinforcements on the underside of the platform main section.

Fasten all bolts and nuts to the prescribed torque. Pressurize the platform against the stoppers [B] to ensure all bolts are properly

secured.

LOWER and LIFT the folded platform at least 3 times. Verify and ensure the platform can unfold and fold freely, without any

interference with the walk-ramp assembly; extension plate, or the vehicle chassis.

Figure 16.2

50 DHOLLANDIA

Since the platform has a lower travel position under the extension plate [distance Y on fig. Figure 16.3], the arms and platform

knuckles will come out further over a distance X [Figure 16.3].

If not premounted, install the 114mm spacer tubes between the side steps and rubber buffers by means of the bolts M10x170

supplied with the kit.

Consult next page for general overview.

Figure 16.3

17 LUBRICATION INSTRUCTIONS

All articulation points equipped with lube fittings should be lubricated after installation (pictured on the following page), and once

in service with intervals as indicated in the maintenance manual.

Use a grease gun to pump grease in the lube fittings, until a grease collar is formed on both sides of the bearing or articulation,

protecting it against ingress of water, salt, sand and dirt.

Note that the grease nipple might be located in the pin itself, or in the larger assembly that pivots around the pin.

In case a pin has 2 grease nipples, grease both sides.

Ensure all lube fittings function correctly and replace any defective fittings.

ALWAYS use acid-free grease. The use of graphite grease is not allowed.

If so equipped, verify if the platform lock operates smoothly, and lubricate with oil if necessary.

NOTICE

To maximize the durability and operational reliability of the tail lift, it is important to lubricate the pivot points thoroughly after

installation.

The OPERATION MANUAL and MAINTENANCE MANUAL are available in the vehicle.

NOTICE WARNING

The PDI check-list completes the final quality inspection of the installation. Once completed successfully, it will certify the safe

and reliable operation of the tail lift.

Operating a tail lift that hasnt successfully passed the PDI can lead to premature wear or damage of the tail lift itself.

Operating a tail lift that hasnt successfully passed the PDI can put the operator and third parties at great risk and could result

in serious personal injury or death.

It is therefore essential that the PDI check is completed with due diligence, and any shortcomings rectified prior to delivery of

the vehicle to the operator.

64 DHOLLANDIA

20.4 SAFE OPERATOR POSITION ON THE PLATFORM

Consult the OPERATION MANUAL section 7.

The operator travelling up and down on the platform, faces 2 main risks:

The operator travelling up and down on the platform, faces 2 main risks:

i. Falling from the platform. Falling from the platform can result in serious body injury or death

ii. Risk of crushing and shearing the limbs between the raising platform and the rear of the vehicle

floor or extension plate. Crushing or shearing limbs or body parts can will result in serious bodily

injury.

To reduce the risk that the operator falls from the platform, DHOLLANDIA recommends that the installer mounts a handgrip to the

rear frame of the vehicle body. Such handgrip will enable the operator to ALWAYS maintain 3 points of contact while lifting or

lowering on the platform. [Figure 20.1]

The handgrip is normally manufacturer by the upfitter or body builder as part of the design of the box, but an alternative is available

from DHOLLANDIA with ref. M1406. [Figure 20.2]

To reduce the risk that the operator crushes their feet between the raising floor and the end of the vehicle floor, DHOLLANDIA

recommends that the installer paints a 16x16 (400mmx400mm) safe operator position at a safe distance of min. 10 (250mm)

away from the inboard platform edge. [Figure 20.3]

A metal paint mask can be ordered from DHOLLANDIA with spare parts ref. EF0100.

NOTICE

To ensure the reliability of the tail lift over many years, it is extremely important that the batteries, their charging system, the

(+) battery and (-) ground cables, fuses and circuit breakers are dimensioned sufficiently strong, and fitted with care following

DHOLLANDIA installation instructions. Insufficient battery power will cause harm and irreparable damage to the electric

components of the tail lift (starter solenoid, electric motor, electric switches, etc...).

Insufficient cable gauge on the (+) battery and (-) ground cables can lead to overheating, bad performance of the electrical

system, and premature wear of the main electrical components.

(-) ground circuits are as important as (+) battery circuits for the good operation of the tail lift, but often overlooked in

troubleshooting. Make sure you take these into consideration when executing repairs or maintenance checks.

DHOLLANDIA mainly uses 2 types of oils in its hydraulic systems:

1. Standard oil: ISO VG 22.

This common and widely available hydraulic oil is used in the majority of DHOLLANDIA lifts, sold for use in normal climate

conditions. This includes all countries excluding the Nordic countries suffering very cold winter climate. Refer to the product

specifications of Q8 - Haydn ISO VG 22 (*) attached for further technical details.

2. Option OAH002 (old ref. S502) = arctic oil 52C: mineral low-temperature hydraulic fluid.

This option is used on lifts sold to countries subjected to very cold freezing temperatures during winter, including Russia,

Ukraine, the Baltic states, Poland, Scandinavia, Canada. Refer to the product specifications of Castrol - Aero HF 585 B (*)

attached for further technical details.

NOTICE

It is important to follow these guide-lines with due care. A lot of oils or fluids used in automotive industry, such as transmission fluids

and ATF oils, are not suitable for tail lift use. DHOLLANDIA has not tested the potential consequences of oils and fluids with deviating

specifications and cannot be held responsible or legally liable for any damage to the tail lift caused by the replenishment with non-

compatible oils or fluids; nor for the consequential damage to property or physical harm to individuals.
