Abstract
A clamp attachment for use with a lift truck for handling rail car bogies. The clamp attachment includes an upper frame that is attached to the carriage of the lift truck for upward and downward movement therewith. A lower frame is movably suspended from the upper frame by four chains. A pair of clamps assemblies are pivotally mounted on the lower frame and actuated by hydraulic cylinders to cause clamping and unclamping of the axles of the rail car bogie for the lifting and lowering of the rail car bogie. A plurality of hydraulic cylinders are arranged to move the lower frame and clamp devices therewith into any desired direction for the maneuvering of the rail car bogie.
