Abstract: A method for providing an extension to the frame of a heavy-duty, off-road vehicle such that the frame is accessible from the posterior area of the vehicle for pushing or pulling. By providing such an extension, the vehicle may pull or be pushed, pulled or bumped without risking damage to the body of the vehicle which typically overhangs the most rearward portion of the frame. In order to allow for rotation of the body to dump loads, the extension is operably coupled to the body and frame such that it is automatically rotated to an out-of-the-way position during the dumping of a load.

Abstract: A combination outrigger stabilizer and lift axle is provided for vehicles such as dump trucks, fire engines, and other similar equipment. The axle is longitudinally extensible, with a ground engaging wheel rotatably mounted on the outer end thereof. A retractable suspension resiliently supports the axle on the main frame of the vehicle, and is vertically movable between a raised, storage position, and lowered, ground engaging position. The axle can be extended longitudinally into an outrigger position, wherein the lift wheel contacts the ground at a location spaced laterally outwardly of the other, conventional wheels of the vehicle, to provide lateral or side-to-side stabilization. While the axle is in the extended, outrigger position, the resilient suspension is deactivated, and the axle is detachably connected directly with the main frame of the vehicle.
Abstract: A lawn debris collection box is mounted, by a slide member, for movement along upwardly and rearwardly inclined guide rods. The box is also mounted so as to pivot upwardly and rearwardly about a connection with the slide member. Also mounted to the slide member for upward and rearward pivotal motion is a pair of drive arms which each have a lost motion connection with the box. A latch arm operative for releasably retaining a hinged lid of the box in a closed position is pivotally connected to the drive arms along with a pair of lift actuators which drive and latch arms to first release the lid, to raise the box until the slide members engage stops at the upper ends of the guide rods and to thus pivot the box to a dump position.
Abstract: A tractor-drawn lift bed dumper trailer for handling high tonnage loads on pallet frame units in intra-plant or over-the-road operations.
