  • Patent number: 6390489
    Abstract: A device that enables a forklift beam to transport trailers or other mobile vehicles whereby a trailer hitch attachment is secured to a hollow shaft at one end of the device and a forklift beam on a forklift vehicle is secured to a hollow shaft at the other end of the device. When both the forklift beam and the trailer hitch are secured to the device, a mobile vehicle or trailer may be secured to the trailer hitch and transported via the forklift. The device may also receive a generic elongated beam in place of the trailer hitch such that the forklift can be used to lift heavy objects for transport such as combustion engines by securing a rope or chain to the engine and then securing the chain or rope around the beam.

  • Patent number: 6024374
    Abstract: A device, or attachment, that allows a person to manually transport small to medium-sized trailers that have a mechanism for receiving a trailer hitch. The device, which attaches to the flat bed portion of a standard dolly, comprises an angled trailer hitch that attaches to the topside of a first substantially flat plate at an obtuse angle with respect to a front end of the first flat plate. There is a second substantially flat plate that is generally parallel to the first flat plate both plates attach to each other at back ends, respectively. The two flat plates are separated by a distance that allows a third flat plate, typically a part of the dolly, to be inserted and secured between them. Once the device is attached to the dolly, a user engages the trailer hitch portion of the present invention to a trailer, and manually transports the trailer using the dolly as the mechanism for directing the trailer.
