ABSTRACT:
An improvement to large container handlers having a transportable platform. A powered positionable support arm is pivotally mounted on one end to the platform for vertical rotation. A L-shaped arm is pivotally mounted from the other end of the support arm to be vertically rotatable. A container gripping device is suspended from the L-shaped arm. In one embodiment, the support arm is mounted to move the L-shaped arm vertically as the support arm is rotated so as to, thereby, raise and lower a container without sidewards movement.
