ABSTRACT:
A system for towing a plurality of wheeled load-carrying vehicles in a train in which coacting tongue and pin members are provided on the vehicles. Each vehicle has a body having a front end and a back end, a pair of fixed position wheels secured to the underside of the body at the back end, a single caster wheel assembly secured to the underside adjacent the front end, and a tongue member mounted on the back end of the vehicle and having an opening in one end. The caster wheel assembly includes a flange secured to the wheel support and a downwardly extending towing pin on the outer end of the flange. To achieve tracking of a trailing vehicle behind a leading vehicle, the tongue on the leading vehicle is moved to a position in which the tongue opening receives the caster wheel pin on the trailing vehicle. A releasable connection is thus made, with the pulling force applied directly to the caster wheel support.
