  • Patent number: 4682931
    Abstract: A load clamp has two selectively openable and closable opposing clamping assemblies, one of which comprises at least a pair of clamp arms movable separately from each other toward and away from the other clamping assembly. Separate actuators for the respective clamp arms are controlled automatically in such a way that, during closure, the respective movements are simultaneous until such time as one of the arms attains a predetermined clamping force, at which time an override system permits their respective movements to become non-simultaneous to enable further closure of the other clamp arm. Corresponding actuator regulation occurs during opening of the clamp arms, the override function being triggered by full opening of one of the clamp arms.
