ABSTRACT:
A method of operating a clamp that includes a first clamping jaw, a support element to which the first clamping jaw is attached and a trigger handle pivotably mounted to a clamp body. The method includes actuating the trigger handle causing the first clamping jaw to experience incremental motion and varying the incremental motion as a function of a load encountered by the support element by varying an effective lever arm of the trigger handle by moving a fulcrum point into contact or out of contact with the trigger handle based on the load.
