Description
1
Lift frame
: mounted in a fixed position under the vehicle chassis. It bears the platform and its load via connection to the lift arms
and hydraulic cylinders.
2
Mounting plates
: used to mount the lift frame to the vehicle chassis.
3
Foldable platform
: carries the load during loading / unloading, lifting / lowering. Consists of a platform main section and a flip-
over point.
3a
Platform main section
: inboard section of the foldable platform. Manufactured from steel or lightweight aluminium, with a
permanent non-slip working surface.
3b
Flip-over point
: foldable, outboard section of the platform. Manufactured from lightweight aluminium.
4
Lift arms L+R
: actuated by the hydraulic lift cylinders, used to LIFT / LOWER the platform and its load.
5
Lift cylinders L+R
: 1 or 2 hydraulic cylinders used to LIFT / LOWER the lift arms, the platform and its load.
6
Parallel arms L+R
: 2 parallel arms, supporting the platform while it travels up and down.
7
Hydraulic pump unit
: contains the electric motor driving the hydraulic pump, the oil tank, and the control valves.
8
Toggle-switch control
: easy-to-use controls to LIFT / LOWER the platform, mostly mounted in fixed position at the side of the
vehicle body, or on the rear post of the body.
9
Bumper bar
: under run protection device, certified conformance to CE legislation.
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.
11
Platform opener
: arm with roller(s) mounted on the lift frame, assisting the deployment of the platform from its travel position to
the work position, then back to its travel position.
12
Extension plate
: heavy duty steel extension mounted to the rear sill of the vehicle floor, with a permanent non-slip surface.
13
Side steps L + R
: steps mounted to the side of the extension floor to help the driver climb into the vehicle from the side. The
side steps incorporate rubber dock bumpers [13a]; support channels [13b] and diagonal braces [13c].
13a
Dock bumpers
: rubber buffers mounted on the rear face of the side steps, to reduce impact damage when the vehicle is backing
into a loading dock.
13b
Support channels
: steel channels welded to the underside of the vehicle body (to the rear sill and support cross members
underneath the vehicle floor).
13c
Diagonal braces
: steel profiles linking the side steps and dock bumpers with the support channels welded to the underside of
the vehicle body. The construction with support channels and diagonal braces aims to distribute the forces of a dock impact over
the rear sill and support cross members of the vehicle body and avoid damage as much as possible.
