There is provided a side shift grappler apparatus to handle or pick up a truck trailer vehicle loaded with two containers and transfer the load from a roadway to a flat bed railroad car. The apparatus is adaptable to adjust or position the loaded truck trailer vehicle on the flat bed railroad car so as to place the fifth wheel of the trailer vehicle over and about the mounting stanchion of the flat bed railroad car for secure attachment thereat.
