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. 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 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 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
Tilt cylinder
: optional hydraulic cylinder used to OPEN / CLOSE the platform. The option OVH004 offers hydraulic instead
of manual OPEN / CLOSE, but does not offer adjustable platform orientation.
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 OPEN / LOWER / LIFT / CLOSE the platform.
11
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.
