1,650lbs.
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.

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 date of
manufacture, etc...
These labels are usually affixed to various liftgate
components, and can be found in following locations (the
yellow arrows point to the serial numbers):
Affixed to the side of the vehicle body, or on the platform
On the lift frame

DHOLLANDIA
DH-VOP.K1 ● MANUAL CLOSURE ● LIFTGATE 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: hydraulic cylinder used to LOWER / LIFT the lift runners, the platform and its load.
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 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 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
Platform lock: pivoting lock on the near-side lift runner with dual function:
1. Platform in vertical position: the hook 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.
9
External Toggle Switch: mounted in a fixed position at the side of the lift column. It contains the electrical switches to LOWER
/ LIFT the platform.
10
Center 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.

DHOLLANDIA
WARNING
Prior to operating the liftgate, the vehicle must be safely parked on level and solid ground, have the parking brake applied, and the
engine switched off. Lock open the rear doors and secure all other moving parts of the vehicle body. Failure to abide by these
instructions can result in serious bodily injury or death to the operator or bystanders.
Ensure that the vehicle cannot tip-over when putting heavy weight on the platform. If the vehicle or the liftgate are equipped with
mechanical or hydraulic stabilizing legs, deploy these before opening the platform. Ensure that the stabilizing legs are positioned
on solid, even ground. In case of soft terrain (sand, gravel), solid support blocks must be used under the stabilizing legs. Failure
to abide by these instructions can result in serious bodily injury or death to the operator or bystanders.
To reduce the risk of serious bodily injury or death which may
result from other vehicles when parked, ALWAYS make sure a
safety distance of 16 ft. or 5 m. is kept between the back of the
truck and the following vehicle.
To reduce the risk of serious bodily injury or death, ALWAYS
make sure the platform is clearly visible to other persons from
all approach directions. DHOLLANDIA recommends the use of
4 warning cones, placed around the work area of the platform.
[See notice below].
To reduce the risk of serious bodily injury or death, make sure
the working zone is sufficiently lighted.
