Abstract: A height-adjusting axle assembly separate from and connectable to a trailer frame. A first pair of wheels is connected to a first cross-beam by a first pair of torsion axles such that rotation of the first cross-beam causes rotation of the first pair of torsion axles. A second pair of wheels is connected to a second cross-beam by a second pair of torsion axles such that rotation of the second cross-beam causes rotation of the second pair of torsion axles. An interconnecting bar is pivotally connected to the first cross-beam and the second cross-beam. A first frame rail and a second frame rail are connectable to the trailer frame. The first cross-beam and the second cross-beam are supported by and extend between the first frame rail and the second frame rail.

Abstract: A height adjusting mechanism for a trailer includes first and second cross-beams, an interconnecting bar pivotally connected to the first and second cross-beams, an actuator that is connected to one of the first cross-beam or the second cross-beam to cause rotation of the first cross-beam and the second cross-beam between a first rotational position and a second rotational position. A locking mechanism is operable move between an unlocked position and a locked position to prevent pivoting of the first and second cross-beams with respect to the interconnecting bar. First and second pairs of wheels are connected to the first and second cross-beams by first and second pairs of torsion axles such that rotation of the first and second cross-beams causes rotation of the first and second pairs of torsion axles.
