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 is
mounted separately on the vehicle chassis.
5
Platform / Foldable platform (optional)
: 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.
5a
Platform main section
: inboard section of the (optional) foldable platform. Manufactured from steel, with a non-slip working
surface.
5b
Flip-over point
: foldable outboard section of the (optional) foldable platform. Manufactured from steel or light-weight
aluminium, with a non-slip working surface.
6
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).
7
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.
8
Tilt cylinders
: optional hydraulic cylinders (option OVH011) used to OPEN / CLOSE the platform, or to TILT DOWN / TILT
UP the platform, and adjust its pitch to the slope of the ground.
9
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.
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.
