Abstract
A hydraulically driven extending clamp is disclosed having a pivoting main body which includes an extendable clamping rod disposed therein. The clamping rod extends above the pivot and is extended by air pressure and retracted by a spring internal to the clamping rod. A retaining member extends through a slot in the clamping rod and forms a travel limit stop as well as a retraction spring contact point. A hydraulic cylinder pivots the main body in seesaw-like fashion to apply clamping forces.
