5.2 Pneumatic installation
For installation in a vertical or inclined position:
Warning
Injury to people and material damage!
If there is a pressure failure, the work mass will
slide down.
• Check whether HGL non-return valves are
required. In this way, you can prevent the work
mass from sliding down suddenly.
• Check whether safety measures are required to
prevent slow sinking as a result of leakage
(e.g. toothed latches, moving bolts or
emergency buffers).

• Select the suitable compressed air supply ports.
In addition to the supply ports provided at the factory (W), there are also the alternative ports (A).
These are fitted with plug screws.
