2.8 Safety devices
Integrated in the switch box is a hydraulic power unit
which generates the necessary pressure to lift the vehi-
cle. This is controlled by valves and moves the cylinders
and platforms upwards via the scissor mechanism. Du-
ring the lifting process, the safety catches engage to pre-
vent the platforms from lowering in case of a defect in the
hydraulic system.
Fig. 3: Protection device in case of hydraulic failure
The left as well as the right side of the base plate is fixed
with an anti-tipper. This prevents a possible tipping of the
vehicle.
Fig. 4: Device for protection against tipping
