The piston rod is clamped if there is a
pressure failure. The clamping is con
trolled separately.
If differential forces are small (with open
clamping), the piston rod can move.
The piston rod is clamped if there is a
pressure failure. The clamping is con
trolled separately.
The system can be set to equilibrium of
forces. Inching operation or moving from
any position without jumps is then
possible.
The cylinder can be exhausted on both
sides.
1) The switching examples satisfy max. PLd/cat 3 for the safety requirement Interrup−
tion of a dangerous movement and dangerous starting up from normal position.
2) Applies only if the movement of the piston rod creates no risk due to the differential
area.
3) Applies only if the equilibrium of forces can be set safely.
