ABSTRACT:
A method and apparatus for a vehicle mounted rolloff hoist having a tiltable frame. The apparatus provides a releasable hinge connection at the rear ends of a base frame and a rolloff frame enabling the operator to select a pivot point which provides for ground contact. The apparatus also permits the operator, once the tiltable frame is in a substantially horizontal position, to disengage the hinge point and advance the rolloff frame on top of the base frame in a lateral direction, securing the rolloff frame within the base frame. At that point, the hinge connection is reattached, and the rolloff frame is secured within the base frame. The result is an improved method and apparatus of a vehicle mounted tiltable rolloff trailer which provides for optimum load distribution, stability and clearance requirements.
