ABSTRACT:
A loading device can be mounted quickly and easily to a roll-off vehicle by mounting a yoke assembly to the frame of the roll-off vehicle. The yoke assembly includes a pair of attaching potions which extend from the vehicle, and each of the attaching portions is provided with an opening. A pair of hydraulically actuated hooks are pivotally mounted on the loading device. The loading device is pulled onto the roll-off vehicle so that the hooks are adjacent the attaching portions of the yoke assembly. The hooks are then pivoted to extend through the openings in the attaching portions so that the hooks are secured to the attaching portions.
