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 gooseneck trailer having rear wheels and a deck for carrying a load includes a gooseneck supported at the front end of the deck for swinging movement between a towing position, abutting the deck front end, in which the gooseneck may be coupled to a tractor, and an open position, to facilitate front loading or unloading. In one embodiment a lever may be extended from the gooseneck to enable it to be swung manually between towing and open positions. In other embodiments the trailer includes a double acting cylinder and a control circuit for selectively applying pressurized fluid to the cylinder to swing the gooseneck between the two positions.
