ABSTRACT:
An improved roll-on, roll-off handling device is provided to lift one end of a container and to maintain it in the raised position during handling and displacement of the container, the device comprising a chassis; a wheel system for supporting the chassis upon the ground, the wheel system permits pivotal movement of the chassis with respect to the ground about a first axis parallel to the ground, the chassis pivoting about the first axis from a tilted position in which a first end of the chassis is adjacent to the ground and a raised position in which the first end is spaced from the ground; a carriage mounted on the chassis and displaceable along the longitudinal axis of the chassis, the longitudinal axis being transverse to the first axis; an apron removably attachable to one face of a container, the apron being connected to the carriage and adapted for pivotal movement with respect to both the carriage and the chassis about a second axis substantially parallel to the first axis; a connecting rod for pivotally displacing the apron with respect to the chassis about the second axis; a jack for moving the carriage and the chassis with respect to each other along the longitudinal axis of the chassis, the carriage being movable between an advanced carriage position in which the second axis is adjacent the first end of the chassis and spaced from the first axis, and a container supporting position in which the second axis is displaced toward an opposed second end of the chassis, thereby to allow movement of a container from a position in which the container rests on the ground with the chassis in its tilted position and the carriage in the advanced carriage position, to a position in which, after movement of the chassis to the raised position and of the carriage to its container supporting position, the end of the container is raised and overlies part of the chassis.
