ABSTRACT:
An apparatus and method for lifting, inverting, and stacking trailer chassis has a pair of support arms engageable with arms of a forklift vehicle and a frame pivotally mounted on outer ends of the support arms. The frame is mounted by engagement of pivot pins on the arm ends with apertures in side members of the frame, the apertures being located inwardly from the center of the length of the side members. This off-center placement of the axis of rotation of the frame enables it to be rotated when the forklift arms are raised without requiring power other than normal forklift lifting power. Clamps including a fixed L-shaped bracket and a cooperating slideable bracket are provided on the underside of the frame for engaging chassis beams of a trailer. A locking pin for securing the frame in a position generally coplanar with the support arms is also provided. In operation, the clamps are secured to a trailer chassis, and the forklift arms are raised while the forklift vehicle is propelled slightly forward to cause rotation of the trailer around a longitudinal axis.
