Abstract
An interconnected series of in excess of twenty-five railroad cars may be shunted about a yard by attaching a vertically displaceable carriage of a forklift truck to the coupler of the first car in the series through a load bearing coupling adaptor and raising the forklift carriage until a sufficient portion of the weight of the railroad car is transferred to the driving wheels of the forklift to give the forklift sufficient traction to move the series of railroad cars. A load-bearing coupling adaptor suitable for such load-bearing attachment of railroad car coupler to fork-lift carriage may be fabricated from a means for rigidly mounting to the fork-lift truck, a coupling pin means for securingly engaging the coupler interiorly of said coupler, and a load-bearing member rigidly connecting the means for mounting to the coupling pin means and extending therebetween at a level beneath said coupler. Means for aligning the means for mounting with the carriage and means for aligning the coupling pin means interiorly of the coupler may also be provided.
