Abstract
A quick-release cam lock for selectively locking the relative position of a hydraulic cylinder and a piston. The quick-release cam lock permits speedy unlocking and repositioning of the hydraulic cylinder and its accompanying piston, thus allowing for speed in repositioning, assembly or disassembly while also providing a secure positive positioning lock between the hydraulic cylinder and the piston while the quick-release cam lock is engaged. A locking pin selectively locks the cam lock in an opened position.
