ABSTRACT:
A vehicle mounted roll-off hoist having a main hoist frame pivotally mounted at its rearward end to a vehicle such as a semi-trailer or truck, and including a pair of hydraulic lift actuators adapted to move the main hoist frame between a horizontal position and a rearwardly inclined position. A hydraulic actuator apparatus is provided for pulling a container onto the main frame of the hoist or setting off the container from the hoist. An extensible and retractable stop carriage is slidably connected to the forward end portion of the hoist main frame. Hydraulic actuator and locking elements are associated with the stop carriage for placing the container in the optimum position for transport on the vehicle. The hoist is capable of handling containers of both the outside rail and the inside rail type.
