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.

Abstract: A height adjusting mechanism for changing the height of a load supporting portion of a trailer. An axle is rotatably connected to a trailer frame of the trailer for rotation between a towing position and a loading position. The axle has a first portion and a pair of axle shafts that are resiliently mounted with respect to the first portion for rotation over a limited angular range of motion and are biased toward a neutral position. A pair of opposed pivot arms are rotatable in response to rotation of the axle between the towing position and the loading position. The pivot arms are rotatable with the axle shaft of the axle in response to rotation of the axle shaft with respect to the central portion of the axle.

Abstract: The present invention relates to a motorcycle anti-tipover device that has telescoping support arms that extend to the ground. The support arms are automatically extending when the motorcycle is stationary or moving at low speeds to prevent the motorcycle from tipping over. The telescoping support arms may also serve as a traditional kickstand, or may be used to lift the motorcycle during servicing. Alternatively, an airbag may be deployed underneath the motorcycle to prevent the motorcycle from tipping over.
