  • Ramp system for assembling and disassembling highway trailers and railtrucks for intermodal transportation
    Patent number: 4989518
    Abstract: A novel ramp system is provided for use in the assembly and disassembly of intermodal highway trailers and intermodal railtrucks for intermodal transportation. The ramp system has an ascending portion for raising the level of the trailer frame onto an elevated portion of the ramp so as to align the respective coupling members in proper relationship for coupling. The ramp system also has a descending portion for transferring the load from the highway wheel assembly of the trailer to the railtruck. The descending portion of the ramp includes a wheel stop to locate the railtruck in an operative location for coupling beneath the trailer during lowering of the trailer frame on top of the railtruck adapter.
