Abstract
An expandable multiple-axle trailer has a trailer wheel carriage with left and right sub-carriages having corresponding forward-extending sub-carriage extensions, the front ends of which define sub-carriage extension tongues laterally movable within slots in a first transverse trailer structure member while being constrained against longitudinal and vertical movement relative to the trailer, while intermediate regions of the sub-carriage extensions are correspondingly laterally movable within fulcrum slots in a second transverse trailer structure member aft of the first transverse member. The trailer wheel carriage incorporates actuation means for transitioning the trailer wheel carriage assembly between laterally-retracted and laterally-expanded configurations. The slots in the first and second transverse members define guide surfaces angularly oriented such that transitioning to the expanded configuration will alter the longitudinal pitch of the trailer wheel carriage to raise the rearmost axle relative to the forwardmost axle, and vice versa when transitioning to the retracted configuration.
