ABSTRACT:
A trailer having a tiltable bed and a wheel-supported undercarriage is provided with structure mounting the undercarriage for reciprocal movement fore and aft of the bed between a forward, bed-tilting position and a rearmost, roading position wherein the bed is carried lower to the ground to accommodate higher loads. The mounting structure includes a pair of tracks on the bed and a series of ramps for raising the bed relative to the undercarriage when the latter is shifted from its roading position such that sufficient spacing between the bed and the undercarriage is provided for clearance of the bed understructure during movement of the undercarriage along its fore and aft path of travel.
