  • Patent number: 9227545
    Abstract: A self-propelled dump trailer comprises a frame, a first wheel driven by an engine, a second wheel, a steering mechanism, and a dump bed that may have its front end elevated by a lifting mechanism. The frame includes a coupler so the dump trailer can be selectively coupled to a vehicle and uncoupled from the vehicle. Further, the dump bed includes a rear gate and a separator gate that divides the dump bed into two sections, wherein the separator gate is operable to place the dump bed into a first dumping position and a second dumping position. As such, the forward section of the dump bed acts as a counterbalance during a dumping operation.

  • Patent number: 8215717
    Abstract: A towable dump trailer is provided. The towable dump trailer comprises a first, second and third frame. The first frame comprises one or more sets of wheels. The second frame is attached to the tow vehicle and can be displaced horizontally relative to the first frame by the towing vehicle moving rearward or forward. The third frame provides a support frame for the trailer bed. The dump trailer is operated by immobilizing the first frame and causing the second frame to move horizontally relative to the first frame. This horizontal displacement causes the third frame to pivot as a result of one or more pivoting arms translating the horizontal movement to pivotal movement. The dump trailer can be configured to provide a dumping action by either forward or rearward horizontal displacement of the second frame relative to the first frame.

  • Patent number: 6715775
    Abstract: A forward dumping, two-wheeled barrow possessing the means to prevent inadvertent rearward dumping and/or injury to the operator is herein disclosed. The primary subassemblies of the forward dumping, two-wheeled barrow include a frame assembly, a wheel assembly, and the cargo receptacle. The frame assembly preferably includes an adjustable length handle assembly and a safety/spill prevention bracket located somewhere between the wheels and the end of the handle assembly. This novel feature prevents potential injury to the operator or nearby individuals (e.g. to the feet) and avoids the problem of emptying all or some of the receptacle's contents in an unintended location. In addition, the safety bracket provides a stable rearward loading position with minimal risk of tipping and/or rolling. The ergonomically designed barrow is fabricated of a variety of strong, lightweight materials (e.g. aluminum, reinforced plastics) to provide a high-strength-to-weight ratio.

  • 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.

    Abstract: A levered, gravity-assisted, side dump utility cart for transporting and dumping objects and materials has load carrying apparatus, bedframe, a rear carriage, a 360 degree rotatable front carriage, four wheels, and towbar unit. A towbar is used as a lever against underside regions of the bedframe by the operator for manually dumping of loads from either side of the cart. Proximate maximum gravity assistance for levered dumping is obtained by unique and predetermined wheel alignments for each selected embodiment of the side dump cart. For such levered dumping, dump alignment devices define the towbar positions where the proximate maximum gravity assistance is obtained for dumping the load with proximate minimum upward and horizontal force on the towbar lever. The range of selectability and the extent of gravity assistance available to the operator for dumping the cart is determined by the embodiment of this invention.

    Abstract: A motorized wheelbarrow with an off-center pivoting Load bucket makes unloading the wheelbarrow easy and quick. The pivot point underneath the bucket is located between a center point of the bottom of the load bucket and a back end of the bucket defined as the end closest to the human operator. A latch holds the bucket in a normal position in which the same is horizontally disposed. Upon release of the latch, since the pivot of the bucket is off-center, gravity will force the bucket to pivot forward into a dumping position, thereby emptying the contents of the wheelbarrow. The wheelbarrow is powered by an engine which further drives a generator, thereby providing electrical power at remote locations.

    Abstract: An improved handtruck having an unloader mechanism for assisting in the removal of cargo from the handtruck. The unloader mechanism utilizes a cargo support pivotally mounted at the lower end of the handtruck. The cargo support is designed so that it can be maintained in a latched position when transporting cargo and can be unlatched to pivot away from the handtruck when unloading cargo. A pusher structure may be operatively connected to said cargo support to facilitate the removal of cargo from said cargo support. The pivot action of the cargo support causes a force to be exerted on the cargo by the pusher structure which urges such cargo down an inclined plane formed by the cargo support, thereby removing the cargo from the handtruck.

  • Patent number: 4629203
    Abstract: A utility cart especially suited for snow removal and other yard work and comprising a generally rectangular body having side panels, a rear panel, and a bottom panel. A pair of wheels are provided at the rear of the body for rollably engaging a support surface and a rounded nose is provided at the front of the body. The rounded nose normally slidably engages the support surface but is rollably engagable with the support surface in response to a generally upward force applied to handle at the rear of the body to facilitate upward rolling pivotal movement of the cart about its nose to dump the contents of the cart out of the open front end of the body. The cart is particularly suited for snow removal but, because of the basic open box configuration of the body, has general application for year round yard work.

  • Patent number: 4313701
    Abstract: In an exemplary embodiment, a U-shaped bracket forms pivot pins by means of the bent-out end areas of the bracket arms, which pivot pins are insertable (and held by the resilience of the bracket) in recesses of the car container sidewalls. The U-shaped bracket has its respective arms engaging in lateral slots of the container insert. The removable container insert may be lowered into engagement with the U-shaped bracket after assembly of the bracket with the car container, with the dimensioning such that the container insert prevents disengagement of the retaining pins. Outwardly inclined parts of the bracket arms may engage in close fitting elongated slots of the container insert so that the container insert pivots as a unit with the supporting bracket.
