Sitema Safety Lock Design

safety lock design

The clamping system consists of a conical clamping sleeve moving within the conical bore of the housing.

The annular piston keeps the clamping sleeve pushed against a set of disc springs.

On zero pressure the clamping sleeve is pressed into the conical housing by the springs to clamp the rod.
