Load Supports
A = Rubber pad
B = Support plate with thread
Support plates take over the load and hold it in position. The rubber pad yields
selectively under load. This protects the vehicle's lifting point and prevents the
vehicle from slipping. If the rubber pad is damaged, this function can no longer
be performed safely. Slipping of the vehicle and a vehicle crash is possible.
Support plates must not have any cracks or chipping. Defective support plates
must be replaced.
The thread on the support plate is used
for height adjustment so that the
vehicle rests evenly on all four support
plates during lifting. This thread must
be smooth-running. Dirty threads
should be cleaned and lightly greased.
The retaining ring on the underside
must be present and correctly fitted.
6.2.6
Piston Rod and Toothed Rack
The piston rods and toothed racks must be visually inspected daily for damage.
To do this, the lift must be completely extended and retracted. The two
components must not show any damage such as scratches, bumps or signs of
corrosion. Damaged piston rods can damage the sealing package and thus lead
to leaks in the hydraulic system.
The piston rods must not falter or jerk during extension and retraction.
6.2.7
Pull-out of the Flat Head Support
The vehicle is picked up via the pull-out of the flat head support. The pull-outs
can be adjusted at fixed intervals by inserting a grooved pin to adapt to different
types of vehicles.
The holes in the pull-out must not be widened or otherwise deformed. The
grooved pin must be seated tightly in the locating hole provided. The
components must be free of corrosion.
