Abstract
A transport vehicle mounted roll-off hoist having a main frame pivotally mounted on the rearward end of a vehicle such as a semi-trailer or truck, including a pair of hydraulic lift actuators adapted to move the main frame of the hoist between a horizontal position and a rearwardly inclined position. A hydraulic actuator winch is provided for lifting a container onto the main frame of the hoist or setting off the container from the hoist. An extensible and retractable stop carriage is telescopically connected to the forward end portion of the hoist main frame. Hydraulic actuator and locking means 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.
