Hand Trucks And Barrows Patents (Class 298/2)
  • Patent number: 11904921
    Abstract: A handcart may include: a support frame; a container; a lock member configured to move between a locking position at which the lock member restricts rotation of the container relative to the support frame and an unlocked position at which the lock member allows the rotation of the container relative to the support frame; and a retainer member configured to move between a retaining position at which the retainer member restricts a movement of the lock member from the unlocked position to the locking position and a non-retaining position at which the retainer member allows the movement of the lock member from the unlocked position to the locking position. The lock member may be configured to move from the locking position to the unlocked position and be maintained in the unlocked position by a movement of the retainer member from the non-retaining position to the retaining position.

  • Patent number: 11752915
    Abstract: An open top debris collection and transport cart with a hitch connector at a first end wall, a pair of wheels at an opposite second end wall, and a bottom panel connecting the end walls. The second end wall is outwardly angled from the bottom panel terminating in a top end, the wheels being positioned adjacent to the ground when the bottom panel is supported on the ground or when the bottom panel is rotated to a vertical orientation and the top end contacts the ground. An elevatable boom connectible to a work vehicle and having a mating hitch connector is provided. Elevating the boom slightly when the hitch is connected supports the cart by the wheels in contact with the ground surface allowing the work vehicle to move the cart. Further boom elevation rotates the bottom panel to a vertical orientation thus dumping the cart contents.

  • 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: 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: 5884924
    Abstract: A wheelbarrow contains a tray, a frame, two legs, two handles, two axle brackets, a wheel axle, and a wheel. The wheelbarrow also contains two spaced apart roll bars extending from the frame in a forward and downward direction to a point forward of the forward edge of the tray, then curving upward and extending vertically for a distance of at least about six inches. The upward curve of the roll bar is located below the wheel axle. The upward curve of the roll bar contacts the ground and forms a fulcrum when the wheelbarrow is raised at an angle of not greater than about 40.degree. and so that the wheelbarrow will balance in a vertical resting position on the vertical extensions of the roll bars if the wheelbarrow is released after being raised at an angle of not greater than about 70.degree..

  • Patent number: 5531463
    Abstract: An attachment for a wheelbarrow adapted to facilitate ease of tilting and manipulating the wheelbarrow while tilted on its sides. The attachment comprises a U-shaped bracket with the bottom portion of the U being positioned orthogonal to the front portion of a wheel of the wheelbarrow and the legs of the bracket extending along and attached to handles of the wheelbarrow. A wheel is attached to each leg of the U-shaped bracket closely adjacent the junction of the legs and the bottom of the U-shaped bracket and adapted to support the weight of the wheelbarrow when the tank of the wheelbarrow is tilted on either side by an operator.

  • Patent number: 5449224
    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.

  • Patent number: 5350030
    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.

  • Patent number: 5256025
    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.
