3. GENERAL INTRODUCTION
• This OPERATION MANUAL explains how the HOLLAN IA liftgate is manufactured; what safety devices are incorporated in its
design; and how to use the liftgate in a correct manner, that preserves the integrity of the machine over the intended lifetime and
helps maximize the safety of the operator and any bystanders.
• The MAINTENANCE AN REPAIR MANUAL (separate) explains how to maintain and service the liftgate in the appropriate
manner, maximizing the safety of the operator and any bystanders, and ensuring the reliability of the liftgate over the intended
lifetime.
4. INTENDED USE
HOLLAN IA liftgates are designed to be fitted to commercial vehicles (commercial trucks, trailers and semi-trailers), and shall be
used exclusively to load and unload the goods transported on the vehicle it is fitted to, within the limits of the load chart, in compliance
with the operator instructions and safety instructions described in this manual.
• Improper use of the liftgate will put the operator and bystanders at great risk of serious bodily injury and death. Therefore it is
strictly forbidden to use the liftgate in a different way, or for different purposes, than described in the operation manual.
• The liftgate must NEVER be used as an elevated work platform, to push loads, to carry people except for the individual
operating the liftgate, or to move snow or other debris.
• The liftgate must NEVER be used as a wheelchair lift.
• Improper use of the liftgate will put the operator and other parties at great risk of serious bodily injury and death. Therefore the
use of the liftgate is restricted to skilled operators only; who have been properly trained, and who know and understand the full
contents of this manual.
• Unauthorized modifications to the liftgate can put the operator and other parties at great risk of serious bodily injury and death.
Therefore, it is strictly forbidden to modify the liftgate and its safety devices in any way.
• Use of aftermarket or non-OEM replacement parts to repair or maintain the liftgate is strictly prohibited and may result in serious
bodily injury or death to the operator or any bystanders.
• This OPERATION MANUAL covers column lifts that are designed to travel above the cylinder beam mounted at the (lowest)
vehicle floor (executions K9 or K9 + K2). If your lift stops at the cylinder beam mounted at the (lowest) vehicle floor (execution
K1), contact HOLLAN IA to obtain the relevant operation manual. See contact info on page 4.

5. IDENTIFICATION
• Every HOLLAN IA liftgate is identified by and labelled with a
uniqu 8-digit s rial numb r (with or without a space
between the first and last 4 digits). Use this number for any
inquiry on a particular liftgate, or when ordering replacement
parts.
• In addition to the liftgate type and serial number, the various
serial number labels provide additional information, such as:
the maximum rated lift capacity and load chart, the bumper
certification number, the date of manufacture, etc...
• These labels are usually affixed to the vehicle body and
various liftgate components, and can be found in following
locations (the yellow arrows point to the serial numbers):
6. DESCRIPTION AND LIFTGATE TERMINOLOGY
• HOLLAN IA liftgates are developed and manufactured using state-of-the-art technology, high quality materials and components,
and highly skilled workmanship.
• The H-VO.07.K9, H-VO.15.K9 and H-VO.20.K9 comprise of a range of column liftgates, designed for a wide variety of trucks,
trailers and semi-trailers, and is available with lift capacities ranging from 1,000 to 4,400 lbs.
• In its travel position, the platform of the column liftgate is stowed vertically behind the vehicle body. Before use, the platform is
lowered approx. 7 “, then tilted open 90 degrees from the vertical travel position, to a horizontal work position.
• epending on liftgate 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:

DHOLLANDIA 7
DH-VO.07.K9 / DH-VO.15.K9 ● MANUAL CLOSURE ● LIFTGATE TERMINOLOGY
See figure below for parts corresponding to numbers in this table
# D scription
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 Cylind r b am: 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 cylind r(s): 1 or 2 hydraulic cylinder(s) used to LOWER / LIFT the lift runners, the platform and its load. K9 executions
have 1 lift cylinder, and offer a lifting height limited to approx. 70” (depending on vehicle width). K9+K2 executions have 2 lift
cylinders, and offer a much higher lifting height.
4 Hydraulic pump unit: contains the electric motor driving the hydraulic pump, the oil tank, and the control valves. The unit 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 cart-stops in the platform
surface, or a retention ramp 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 runn rs: 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 left and right side at the inboard platform edge. 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: up and down sliding lock on the near-side lift runner with dual function:
1. Platform in vertical position: the lock holds the platform closed against the lift runners. Release the platform lock to open
the platform.
2. Platform in horizontal position: 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.
10 Main xt rnal 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 C nt r point of maximum load: point up to which the maximum rated capacity of the liftgate is valid. Beyond that point, the
maximum safe working load diminishes according to the applicable load charts found at Section 8 of this manual.
