ABSTRACT:
Hitch apparatus is disclosed with particular application to open-topped bulk-haulage trailers, the hitch apparatus comprising a pair of hitch beams which are joined at a hitch pin at the front of the trailer and diverge laterally and rearwardly to join to the front corners of a hopper or the like. The ends of the hitch beams remote from the hitch pin are joined by a cross-beam which reacts the transverse component of the bending moment generated within the hitch beams by the longitudinal offset between gravity forces in the hopper and the hitch pin. The hitch beams and the cross beam are preferably formed from fabricated I-beam sections to maximise the structural efficiency.
