The safety clamping unit "System RINGSPANN" clamps piston rods of hydraulic or pneumatic cylinders independent of the direction of movement. It clamps with disc spring force and is released by hydraulic or pneumatic pressure. The units are fitted to cylinders ond other machine parts with a connecting flange.
catalogue No.32 Hydraulic Safety Clamping unit
Applications:
- Securing presses during tool changing
- Positioning of winch installations and rollers
- Securing of hydraulic/pneumatic adjustments
- Securing of elevating platforms
- Securing of working cylinders, even under water
Operation:
During the working stroke of the cylinder, hydraulic or pneumatic pressure is exerted onto the connection of the unit. Through this pressure discs springs are compressed and the internal clamping discs become axially free. The piston rod can move freely. When the pressure is removed, the force of the springs works fully onto the clamping disc pack, which performs radial force onto the clamping sleeve. The sleeve is slotted and transmits the full radial force evenly onto the piston rod, thus making it absolutely immovable.
