  • Patent number: 6357986
    Abstract: The device of manual transporting large objects or loads, which includes a wheeled, load supporting frame vertically adjustable, facilitates the manual load, unload, and transport of large objects or loads, such as pickup truck toppers or shells, sheet material, pipes, other building supplies, appliances, etc. Frame height adjustment to the level of on or off load is by means of telescoping legs, supported on lockable wheels or castors, or in combination with hand winches mounted on the legs. Rollers may be attached to the top of the frame for ease in sliding objects or loads on or off. In an alternate embodiment for elongated objects or loads, such as pipes, beams, rails, etc., a beam and additional supports are added to the frame. The device is positioned over the load. The load, such as a pipe, is attached to each end of the beam by chains and transported to an interim workstation or its final disposition.
