ABSTRACT:
A semi-trailer has two multi-wheeled undercarriage assemblies, at opposite sides of its longitudinal centerline. Each comprises a first laterally extending beam medially pivotally connected to a longitudinally extending beam which can be raised or lowered relative to the trailer body, a pair of second beams, one transverse to each end of the first beam and each medially pivotally connected to the first beam, and at least one wheel rotatably mounted on each end of each second beam. The pivotal connections of the beams with one another and with the body enable all wheels to share equally in supporting the load.
