  • Patent number: 6755479
    Abstract: A trailer for attachment to a hitch of a tow vehicle, the trailer comprising a bed, or some other type of load carrying portion, connected for pivotal movement with respect to the draw bar of the trailer. The bed is movable between a generally horizontal, hauling position and a tilted, dumping position. The bed includes a forward portion adjacent the draw bar and a rearward portion opposite the forward portion. An axle is connected to the bed to which wheels are attached. Blocking members contact the axle as the tow vehicle moves rearwardly, the blocking members being movable between a blocking position, for contacting the ground to substantially block rearward movement of the bed as the trailer is moved rearwardly, and a retracted position, wherein the blocking members are substantially out of contact with the ground. Upon the blocking member being moved to the blocking position and the bed being in the hauling position, and upon the trailer being moved rearwardly, the bed pivots to the dumping position.

  • Patent number: 6302380
    Abstract: A portable extraction tool facilitates soil stabilization applications that utilize compaction grouting. Compaction grouting involves installing grout injection casing into the ground in fixed-length sections to depths limited by soil compaction or bedrock. The casing is then removed in stages. Between stages, grout is pumped through the casing and into the soil at high pressure. The extraction tool provides the power, gripping strength, stability and operator control required to pull casings from the ground at a desired rate. Pulling power is provided by a pair of hydraulic cylinders. Gripping strength is provided by a progressive chuck mechanism that secures injection casings on upward movements of the cylinders and releases casings on downward movements, without damaging the reusable casings. Stability and strength are provided by a heavy, large-footprint base plate.

  • Patent number: 6193319
    Abstract: A handle-propelled, load-carrying land vehicle comprises a frame having two parts, one having wheels and ground-engaging pedestals forward of the wheels, and the other being pivoted to the front of the first part and having a load-carrying receptacle mounted on it and having a telescoping handle. The device is balanced so that it can be easily propelled by pushing downward and forward on the handle. It is especially useful as a dumping hand cart for granular loads, since the forward edge of the receptacle is spaced from the ground at least at the completion of the dumping operation. A gravity-operated latch keeps the frame parts together to allow the load carrier to be pulled up steps, up a slope, or up over a curb without having the wheels separate from the receptacle, but automatically releases, allowing the user to dump a load of material from the receptacle by pushing forward on the handle.

  • Patent number: 4494797
    Abstract: A trailer of the type for use in supporting machines such as snowmobiles, lawn and garden tractors and the like. The trailer includes a frame supported for pivotal movement about the axis of the trailer axle such that the rearward end of the trailer can move toward the ground such that the bed of the trailer is inclined to thereby facilitate loading of a machine onto the trailer. The trailer also includes a draw bar having a forward end including a hitch device adapted to be connected to a vehicle, and the rearward end of the draw bar is pivotably connected to the trailer frame and bed forwardly of the vehicle axle. A lever assembly is also provided for mechanically lifting the forward end of the trailer bed with respect to the draw bar so as to cause the rearward end of the trailer to move downwardly toward the ground to a loading position.

  • Patent number: 4145085
    Abstract: A bellcrank lever is pivotally connected at its elbow to a tow vehicle such as a tractor. A generally horizontal arm of the bellcrank lever is pivotally connected to the lower front portion of a trailer bed through a universal joint and a centering mechanism. The after end of the bed is supported by two rear wheels. A hydraulically actuated mechanism connected between the vehicle and an upwardly extending arm of the bellcrank lever pivots the bellcrank lever in a vertical plane thereby selectively raising or lowering the front of the bed. The universal joint allows towing and dumping at a considerable angle of lateral tilt of the bed relative to the vehicle and the centering mechanism maintains the trailer in fore and aft alignment.

  • Patent number: 3977726
    Abstract: A hitch extends between a towing vehicle such as a tractor, and a trailer includes an upper hitch and a lower hitch together with a releasable latch means holding one against the other. When released, back up of the towing vehicle and, if necessary, applying the brakes of the trailer, tilts the trailer rearwardly and continued backing up tilts the trailer over through nearly 180.degree. for full dumping. When the towing vehicle is moved forwardly the trailer returns to the towing position and the latch means may be re-engaged between the upper and lower hitches.

  • Patent number: 3936070
    Abstract: A cart-like vehicle has a symmetric concave body portion which is pivoted on a frame on a tilt axis above the axis of the wheels so that the cart may be tilted in one longitudinal direction to serve as a personnel conveyance, or may be loaded with its carrying compartment upright and unloaded by merely tilting the body in a second longitudinal direction to a dumping position. The body portion is substantially wedge-shaped, with its tilt axis closer to the top than to the bottom, so the body may be readily pivoted in either longitudinal direction. Both of said axes lie substantially in the transverse, vertical mid-plane of the body when said body is upright. Means are provided to support a seat for using the cart as a passenger vehicle when tilted in one direction, and the cart also includes means for supporting a cover or shelves when the cart is used to convey liquids or as a free-standing serving cart.
