ABSTRACT:
A clamping device for securing a load on a hand truck is attached to either outer side tube of the truck. The clamping device can be moved vertically on a guide rod which is attached to the outer side tube when the operator has actuated a release lever. After an extension bar, having a variety of possible shapes is positioned on the load, the operator presses the clamping device down on the load and removes the actuating force on the release lever. This locks the clamping device in place and secures the load on the truck. A set of floating clamps allows minimum load shifting and locks the clamping device on the guide rod when so desired by the operator.
