ABSTRACT:
A dual clamp for automotive frame straightening machines includes a first clamp assembly and a second clamp assembly both of which are slidably mounted to an elongated slide bar. The first and second clamp assemblies are identical and comprise respective first and second pivoting jaws pivotally mounted to corresponding first and second sliding jaws. A chain interconnects the lever end of the first pivoting jaw and the lever end of the second pivoting jaw, so that when a pulling force is applied to the chain, the chain simultaneously pulls on both clamps and increases the clamping force of each respective clamp assembly.
