  • Patent number: 9388029
    Abstract: A tank handling apparatus for facilitating movement of cylindrical tanks such as oxygen tanks as needed which includes a carriage assembly with a main upright member and a parallel swing arm assembly extending outwardly therefrom with multiple lifting arms with a tank retaining housing movably secured thereto which defines a zone therein for receiving of the cylindrical tank. The apparatus provides movement capability vertically upwardly and outwardly, as well as rotational movement of the tank retaining housing to facilitate changing orientation of the position of a different tank between a horizontally extending position and a vertically extending position. An automatic locking mechanism is included which is gravitationally powered for facilitating deployment of a foot support member beneath the tank receiving zone in all positions other than when the held tank is horizontally positioned.

  • Patent number: 9139214
    Abstract: An adjustable lift truck having a frame with a first end and an opposing second end. The frame defines a longitudinal axis that extends from the first end to the second end. A pair of transport wheels are rotatably mounted to the frame proximate the first end. A pair of laterally spaced-apart outriggers extend generally perpendicularly to the longitudinal axis of the frame. Each outrigger is located proximate the first end of the frame, and includes a first end pivotally attached to the frame and an opposing free second end.

  • Patent number: 9120498
    Abstract: A log handling assembly includes a cart that is positionable on the support surface. A wheel is operationally coupled to the cart. The wheel engages the support surface. A restraining jaw is coupled to the cart. The restraining jaw may engage the log. A handle is coupled to the cart. The handle is gripped by a user. The user urges the handle upwardly. The cart is tipped forwardly so retraining jaw engages the log. A gripping jaw is operationally coupled to the cart. A lever is operationally coupled to the cart. The lever is operationally coupled to the gripping jaw. The user urges the lever. The lever urges the gripping jaw so the gripping jaw engages the log. The gripping jaw retains the log between the gripping jaw and the restraining jaw. The cart is movable along the support surface so the log may be transported.

  • Patent number: 9079599
    Abstract: A method and apparatus is provided for improved hand trucks. In some embodiments, a hand truck has side members extending from the frame to help retain objects being moved with the hand truck. The side members extend outward from the frame of the hand truck to prevent round objects from rolling sideways off the hand truck while in transit.

  • Patent number: 8794898
    Abstract: A hand-operated hay bale cart has only two wheels connected in a laterally spaced-apart fashion to a generally rectangular handle frame. The handle frame is generally near the top, or above, the wheels, creating an open space beneath the frame and between the wheels for receiving a bale of animal feed. Pivotally supported by the handle frame is a securement rack that swings freely on a horizontal axis and includes a set of curved hooks at or near both the front and back of the securement rack. A hook handle operates the hooks to rotate relative to the rack to impale the hay bale. The securement rack, if it is allowed to rotate freely, including when it has impaled and secured a bale of hay, may balance the lifted bale of hay between the two wheels for convenient transport.

  • Patent number: 5042962
    Abstract: A hand truck particularly adapted for the movement of extremely heavy barrels has a wheeled base platform to which is pivotally attached a barrel holding frame having a forward vertical position and a braced reclining position against the truck. The barrel frame has its pivot point located at a sufficiently forward and low position so as to achieve approximately a ninety to one lever arm from the truck handle to the pivot point. The barrel frame has two lower barrel holding hooks. A pivoted barrel grasper, a lever arm having a pair of offset, facing grabber hooks, is positioned by means of a moveable pivot pin so as to engage the top lip of a barrel. In use, the barrel truck is moved in the erect position adjacent to a barrel; the grasper is positioned so that the grabber hooks enclose the upper rim of the barrel.

  • Patent number: 4981412
    Abstract: A modified hand truck with a novel structure that optimizes the cooperation between the carrying platform and the wheels in order to produce the maximum lifting force possible for the operator. The wheels are free to move in relation to the carrying platform, thus tilting of the load to the extent desired is possible before lifting becomes necessary. In addition, because the invention minimizes the impact of the size of the wheels on the lifting action, large wheels are used to improve the rideability and stability of the truck.

  • Patent number: 4685854
    Abstract: A hand cart particularly adapted for carrying a stack of material such as tires, barrels and the like utilizing a pair of arms activated by foot pedals to open and close the arms. The foot pedal mechanism is arranged such that the pedals will always be horizontal during the opening or closing of the arms. Two horizontal projections from the end of each arm provide horizontal support of material to be moved. The projections from the arms are scalloped to minimize friction during engagement. No adjustments for material size are required in the use of this device. The arms are arranged to have the maximum length possible to minimize the opening angle to reduce interference with adjacent stacks.

  • Patent number: 4194853
    Abstract: A method of producing a ground covering from individual paving stones by arranging a group of individual paving stones in the form of a section of the ground covering to be produced, grasping the group by means of a lateral compressive force from two opposed sides leaving out the lower range of the paving stones in laid condition, hoisting and moving the group thus grasped to the place of laying, and depositing the group there. The vertical distribution of the compressive force is so selected that it is greater in the lower range of grasp than in the upper range of grasp.An apparatus for carrying out this method includes a laying vehicle which carries a gripping tongs, the gripping faces of which are movable at least vertically by a means of the laying vehicle and are formed by linings diverging from the bottom to the top.
