8.3 Description of Anti-Drop Safety Device

the detents of the inner scissoring. After the lifting motion the safety catch should be fully engaged on
both sides to ensure safety.


The safety catch is lifted up by means of the cylinder during lowering movement. At the end of the
lowering movement or by interruption of the movement, the safety catch automatically drops and
thereby grips into the detents of the service lift.
Should the service lift not lower:
In this case briefly lift the service lift until the drop is free. Afterwards repeat the
lowering movement.
