Information

Swing clamps GN 876 are used when the clamping point for inserting and removing the workpiece must be freely accessible on top.

The design allows especially space-saving mounting. The height of the swing clamp can be adjusted via the screw-in thread.

During the clamping action, the arm is first swiveled by 90° and lowered, followed by the linear tensioning motion. The workpiece clamping must take place within the clamping stroke.

The angle orientation of the clamping arm can be set arbitrarily during mounting on the swing clamp. When tightening the screw, the piston rod must not experience any torque. The clamping arm must therefore be held to prevent twisting.
