WARNING!
Personal injury and material damage!
If there is a pressure failure, the working load will fall.
•
Check whether HGL check valves are necessary. This prevents the moving load from suddenly slip-
ping.
•
Check whether safety measures are required to prevent slow sinking as a result of leakage (e.g.
toothed latches, moveable bolts or emergency buffers).
•
Select the appropriate 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.
