Abstract
A carton clamp having a frame adapted to be mounted on a materials-handling machine, especially an automatically guided vehicle, includes clamp arms coupled directly together, independently of the frame, by motor-driven screw-type linear actuators which selectively open and close the arms. A centering assembly coupled to each clamp arm corrects for any imbalance of clamp arm speeds relative to the frame which may occur due to the fact that the screw actuators are free to move relative to the frame. The direct interconnection of the clamp arms by the screw actuators effectively doubles the clamping force which would otherwise be obtainable if the actuators were fixed to the frame.
