Having Transpositioning Base And Erecting Means Patents (Class 182/63.1)
  • Patent number: 8985275
    Abstract: A lift safety system that prevents the lifting of a support platform from a support base until all of the support legs for the support base are supporting a minimum amount of weight to ensure stability of the lift. The support base includes a plurality of legs that extend outwardly with each of the legs having an adjustment member with a pad that engages a ground surface. As the adjustment member is adjusted downwardly with respect to the leg, a first engaging member connected to the adjustment member is elevated upwardly to engage a second engaging member thereby releasing a corresponding finger member attached to the support platform from the support base. Once all of the legs are supporting a minimum amount of weight, all of the finger members are released from the support base thereby allowing elevation of the support platform.

Typically an aerial lift is coupled to a vehicle via a turntable. The turntable includes a counterweight on a rearward side of the turntable to balance the booms and associated hardware as they are extended in a forward direction. If the booms are in certain rearward, or even vertical positions, the counterweight can cause the vehicle to tip and such unstable positions are to be avoided. By providing the bell crank proximate the pivot joint between upper and lower booms, with the bell crank coupling at pivot joints with: the lower boom, the mechanical link, and an upper hydraulic cylinder, the booms of the aerial lift system are mechanically constrained to avoid vehicle tipping.

    Abstract: A vehicle for lifting a load with respect to a support surface includes a load carrying member configured to carry the load, a frame, and a support assembly coupling the load carrying member and the frame. The support assembly is configured to move the load carrying member between stowed and deployed positions with respect to the flame. The vehicle further includes a plurality of motion devices that support the frame relative to the support surface, and the motion devices are configured to move the frame along the support surface. In addition, the vehicle includes a control system associated with the motion devices and configured to determine contact forces between the motion devices and the support surface. The control system is further configured to determine stability of the vehicle based on the contact forces.

  • Patent number: 7815015
    Abstract: A towable elevatable stand includes a platform that is always elevated above a trailer bed to at least a minimum elevation, but can be easily raised to selected elevations up to almost double the minimum elevation. This allows for carrying ATV, supplies, etc. on the trailer bed under the platform. Telescoping corner posts with latch pins for securing the platform at selected elevations can be combined with a simple winch, pulleys and cables for raising/lowering the platform. Commercially available parts, light weight materials, and a simple elevating apparatus produce a light weight, cost effective stand that is easy to use, tow and maintain, and which minimizes wind resistance. The platform is perforated for drainage and light weight, and the blind is a pop-up tent that is stowed for towing.

  • Patent number: 7735605
    Abstract: A method for erecting a platform is presented. The method includes providing a selectively liftable platform mechanism wherein the platform mechanism generally includes a platform, a trailer, at least one support bar, and a ladder. The at least one support bar and the ladder provide structural support for the platform when the platform is raised above the trailer. The at least one support bar has a proximal end pivotally connected to a first end of the trailer, and a distal end pivotally connected to the platform. The ladder has a distal end pivotally connected to the platform, and a proximal end pivotally and slidably connected to the trailer. The proximal end of the ladder is movable along a longitudinal axis of the trailer in order to level the platform in its raised position. The platform mechanism also includes a cable operatively connected to the platform.

  • Publication number: 20090229914
    Abstract: A device is provided which can be converted from a transporting cart to an erecting hoist for a hunter's tree ladder stand. The device includes components which can be assembled into the cart, disassembled, and re-assembled into the hoist which allows one person to transport the ladder stand, and to raise and lower the ladder stand to and from a position against a tree. The hoist includes a clamp with jaws which can be operated by the hunter on the ground so as to secure the hoist to the tree. A rope or cable extends through a pulley on the hoist so that the ladder stand can be raised into position by a hunter, single-handily. The hunter can then climb the ladder stand, which is secured to the hoist, which is secured to the tree, and further attach the platform of the ladder stand to the tree with one or more straps.
