Abstract
A container and trailer-handling combination yoke having lifting arms mounted at the opposite ends of two transversely extending, longitudinally spaced yokes interconnected by a telescopically extensible frame, are mounted for pivoting between respective generally vertical, operating positions and generally horizontal elevated positions. The arms are mounted to the respective yoke ends via respective intermediate members which are themselves pivotally mounted to the yokes about respective generally horizontal, longitudinally extending axes, so that the elevated arms may be swung inboard to storage positions lying transversely inboard of the respective ends of the yokes. Preferably, hydraulic double cylinders are used for swinging-up the lifting arms.
