The method of the present invention is also adaptable to being employed in piggy back transportation of semi-trailers or intermodal shipping containers on railroad cars. The apparatus of the present invention is designed for flexibility in use and ease of assembly and disassembly which comprises lift assemblies based on the use of ball screws powered from flexible cable drives.
