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.
