Emergency lowering in case of power failure or defective valves
In case of power failure or defective valves the hydraulic valve for lowering of the lift,
there is the possibility to lower the lift by opening the hydraulic valve manually, so the car
can be driven off.
In case of power failure emergency lowering can only be performed when the
ratchets are not engaged (when the ratchets can be pulled back manually). In
case of defective valve the lift can be lifted a little bit by turning key to lifting
position (to right side) So there is the possibility of pulling back the ratchets
manually.
The emergency lowering must only be performed by persons instructed to use
the lift. Please refer to the regulation "Lowering".
• Pull back the ratchet manually and lay a suitable support (wedge, cloth) between the
ratchet-strip and the ratchet or fix the pulled-back ratchet with the help of a wire. So
the ratchet tooth of the ratchet can not engage in ratchet-strip any more. This step
should be taken at all of the four columns.
• Loosen emergency lowering screw (set screw) for one turn to start the lowering
(the emengency lowering screw is on the side of the rail);
