clamping: for clamping, the cylinder piston pushes the clamping lever into the clamping position. Released by the hydraulic sequence control, pressure is then applied to the clamping and locking mechanism. Once the clamping force is built up, the clamping element is self-locking. This mechanical lock prevents unintentional unclamping of the die even if there is a loss of pressure.
unclamping: for unclamping, the clamping and locking mechanism is hydraulically unlocked. Released by the hydraulic sequence control, pressure is applied to the cylinder piston which pushes the clamping lever into the unclamping position. Unclamping and clamping positions are monitored by inductive proximity switches.

special features: rugged and compact design and well-proven clamping element with high degree of safety and long service life high functional reliability ensured by position monitoring and an automatic cycle self-locking by mechanical lock and easy installation
