The clamping principle of toggle clamps GN 862 work according to the toggle principle: lever and clamping bar move in the same direction. They can be mounted in two planes via the dual flanged mounting base and require less space for the clamping action because the clamping arm and the operating lever move in opposite directions.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 862 have a permanent magnet integrated into the piston.
