Ground Engaging Patents (Class 298/17SG)
  • Patent number: 6019568
    Abstract: A portable, low-profile tipper, for dumping the contents from a trailer containing dumpable material, includes a towable, elongated frame having a back end with a deck pivotally attached thereto. The deck has a backstop for positioning the trailer during dumping. Actuators raise and lower the deck to effect dumping. The tipper includes a chute for guiding the dumpable material from the bottom of the trailer past the back end of the frame. Pivotally mounted to the deck rear end beneath the location of the rear end of a trailer supported on the deck is a gate which contains on the deck any materials spilled from the trailer during dumping until it is desired to remove the material from the deck, whereupon the gate can be opened when the tipping platform is elevated and the spilled material permitted to discharge onto a supplementary chute that guides the material away from the tipper frame.

  • Patent number: 5344271
    Abstract: A portable low-profile tipper for dumping the contents from a trailer containing a dumpable material, includes a towable elongated and angled frame having a portion resting on the ground during dumping for greater stability. A deck is pivotally attached at an elevated position to the frame back end. The deck has a backstop for positioning the trailer during dumping. Actuators raise and lower the deck to dump the trailer contents. The tipper has a chute with fixed and pivoting components cooperating to guide the dumpable material from the trailer past the frame back end. Front and back stabilizers extend outwardly from the frame. The front stabilizers lift and lower the frame front end between a low-profile dumping position and a raised towing position. A method of successively removing the contents from a plurality of trailers using the tipper is also provided.

  • Patent number: 5102198
    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.

  • Patent number: 5080548
    Abstract: A portable low-profile tipper for dumping the contents from a trailer containing a dumpable material, includes a towable elongated frame having a back end with a deck pivotally attached thereto. The deck has a backstop for positioning the trailer during dumping. Actuators raise and lower the deck between a lowered position adjacent the frame and a raised position for dumping the trailer contents. The tipper includes a chute having fixed and pivoting components which cooperate to guide the dumpable material from a back opening of the trailer past the frame back end. The tipper frame has outwardly extending front and back stabilizers. The front stabilizers lift and lower a front end of the frame between a low-profile dumping position for receiving the trailer and a raised towing position for hitching and towing the tipper between dumping locations.

  • Patent number: 4711500
    Abstract: Stabilizing apparatus for a dump vehicle including a dump box pivotally movable about a frame between lowered and elevated conditions utilizes two leg members each having two end sections which are movable relative to one another in a telescoping fashion and hydraulic cylinders for telescopically moving the end sections of each leg members relative to one another. One end of each leg member is connectable to the dump box adjacent a corresponding side thereof for pivotal movement relative thereto between a first condition at which the leg member is positioned generally alongside the box for storage and a second condition at which the leg member extends angularly downwardly from the box for engagement of the other end section of the leg member with the ground.

  • Patent number: 4576390
    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.

  • Patent number: 4523788
    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.

  • Patent number: 4382631
    Abstract: A seed cotton transport is provided to transport seed cotton from the cotton stripper or harvester to a module builder. The basket upon the trailer or transport is pivoted about a point which is elevated above the sides of the module builder which is approximately eleven feet above the surface of the ground. The pivot is outboard of the wheels of the trailer. In the dump position, the weight is primarily to one side and as indicated above is very high. To prevent the trailer from overturning, stabilizing struts are hydraulicly extended any time the tilt or dump cylinders are pressurized to elevate the basket. A restricted one-way valve is used to insure that the cylinders operate in proper sequence.
