20080238034Tow-bar for wheelbarrows - A tow bar assembly for converting a two-wheeled wheelbarrow into a garden or industrial type trailer includes a bar of metal box tubing with horizontal holes at the wheelbarrow end and vertical holes at the tractor end. The wheelbarrow end is slid onto the axle of the wheelbarrow, keeping the bar between the tub of the wheelbarrow and its toe plate. Grommets positioned on the axle on either side of the bar center the tow bar assembly on the axle. A threaded post is inserted into the holes in the tractor end of the bar and locked into place by nuts. In use, the handles of the wheelbarrow are raised and the post inserted into the aperture of the tractor's draw bar from the underside of the aperture. The cantilevered weight of the wheelbarrow will keep the wheelbarrow from becoming disengaged from the garden tractor or towing vehicle. The legs of the wheelbarrow are kept off the ground and the trailer-barrow is now ready for use. Where the wheelbarrow conversion to a trailer is intended for heavy loads, a piece of flat iron is attached to the topside of the rails of the wheelbarrow close to its dumping end. In this way, when in use, the tow bar will rest on the flat iron instead of the wheelbarrow's toe bracket.10-02-2008

20110148073Rear Outrigger for Wrecker - A device relocates an underlift/vertical arm assembly from the end of a sub-frame to the boom of a wrecker, and hence whole space of the end of sub-frame is used to design rear outriggers that will certainly exhibit an excellent performance. An advantage of a large space for this specific application is to design a wider span of rear outriggers, as completely extended, to match that of the front outriggers, and in the mean time, the tip of a rear outrigger has a sufficient strength to maintain a good stability. The increased length of overlapping part in each section of the three stage outriggers assists to achieve this goal. As the three stage outriggers are fully extended, the tip of each right/left side is additionally reinforced by a diagonal folding bar which bridges between an outer vertical barrel and the end of primary inner sleeve. Consequently, a combination of wider spans and higher stiffnesses at the tip of the rear outrigger provides the wrecker with a superior stability. Besides, the sophisticated rear outriggers are easier to operate because it may be a single hydraulic control system. The combined results give the best rear outriggers in the towing industry.06-23-2011
