  • Publication number: 20130058745
    Abstract: An open center trailer with spring suspended axels which straddle a detached cargo bed, which was loaded on the ground, said trailer level lifts the cargo bed by pulling said cargo bed up its channel ramps to an elevated transport height, and consequently level lowers and detaches from this load bed at another location. This load may be a cargo utility platform, or an enclosed cargo box, or a horse traveling compartment, or a dump bed, or a highway light, or a traffic speed sign.

  • Publication number: 20120213622
    Abstract: A hauling system that has a chassis and a fully detachable cargo bed. The cargo bed can be elevated into a fully loaded, ready for transportation position, and fully unloaded, while remaining level to the ground on which the overall device is operated. The chassis and the cargo bed are equipped with beveled pieces that interact to help guide the operator when maneuvering the chassis into a staged position on the cargo bed. The cargo bed of the detachable level lift hauling system may be secured to the head end of the chassis when the cargo bed has been pulled up to the transportation position.

  • Patent number: 4703786
    Abstract: An improved stump grinding apparatus wherein the design and location of the components encourage the operator to stay at the handles which are located away from the cutting wheel while it is rotating. The cutting wheel rotates whenever the engine is running, and, because the apparatus is supported by a pair of tires and its weight is balanced slightly forward of the tires (the end with the cutting wheel), the rotating cutting wheel will fall to the ground whenever the operator lets go of the handles. Further, because the underside of the cutting wheel is exposed at all times, if the operator releases the handles without first stopping the engine, the cutting wheel will dig into the ground. The apparatus also has an angular side chute aft of the cutting wheel which deflects wood chips from the stump being ground to the side of the apparatus.
