Patent

CA 2110546

A pair of main beams, a plurality of diagonal cross braces and transverse beams having a beam height of about 75% of prior art main beam heights provide a relatively flexible chassis. A clamp assembly central of the chassis clamps a cubicle cargo container central region to the chassis to rigidify the chassis. The cargo container is connected to the chassis front and rear by conventional bolster pin and twist lock assemblies. An upper container casting has an opening for receiving an interbox twist lock connector aligned on an axis closely spaced to the side panels of upper and lower containers on a rail car to minimize bending loads on lower container intermediate support posts. Lower castings at the base of each of the intermediate posts mate with a lower container upper castings in a stacked arrangement on a rail car. The chassis has a bogie assembly receiving channel for slidably receiving a bogio locked to the chassis by a conventional retractable pin mechanism. The container tunnel has a trapezoidal transverse section which mates with a chassis goose neck which is 10% narrower than and about 50% the vertical height of prior goose necks.
