ABSTRACT:
Two independent modules, disposed on a mobile handling platform, each comprise an endless chain with a pulling finger and a pushing finger. The operations of the chains are symmetrical with respect to the load drive axis. In operation, the pulling fingers engage a handle on the front of a load container and drive it until the pulling fingers reach a portion where their movement is lateral to the drive axis, temporarily stopping the container movement until the pushing fingers engage a handle on the back of the load container, serving to clamp the container during movement of the platform. Releasing the container can take place on the same side as that of loading by reverse rotation of the chains or from the opposite side by continuing the movement of the chains in the same direction, in accordance with an equivalent procedure. The modules are movable transversely with respect to each other under the control of a single motor driven reducer so that the spacing therebetween may be adjusted between a side by side position provided for gripping loads of minimum width and a spaced apart position for gripping loads of greater width.
