Heavy duty pneumatic toggle clamps GN 861 have been constructed in such a way as to make them easy to unmount. The bearing pins are axially fixed with circlips. This allows the clamping bar to be modified to suit any particular application.
To ensure an extended life of the mechanical parts as well as the air cylinders, the operating pressure should not exceed 6 bar and a compressed air maintenance unit should be installed upstream.
Toggle clamps GN 861 have a permanent magnet integrated into the piston. In conjunction with sensors GN 3380 , it is possible to detect the piston position, which can deliver a signal, for instance to a machine controller.
