PowRLock - Hydraulic Swing Clamps

PowRlock Hydraulic Swing Clamps are designed to automate simple fixture setups while providing reliable and efficient workpiece clamping. Featuring a unique sequential motion, the clamping arm rotates 90 degrees over the workpiece before applying a downward clamping stroke with forces up to approximately 5,000 pounds. This design allows for unobstructed loading and unloading while delivering consistent clamping performance for a wide range of machining and manufacturing applications.

When paired with a Wilton booster or pump, a simple valve operation activates the clamping cycle, while releasing the valve causes the arm to swing clear of the work area and return to its rest position. Standard models provide clockwise arm rotation, with counterclockwise movement available through a simple adjustment. Their automated operation helps improve productivity, reduce setup time, and streamline fixture design in demanding production environments.
