  • Patent number: 6244603
    Abstract: A hand truck for transporting a craft such as a jet ski, snowmobile, or sailboat has a frame that is open at one lengthwise end, having lengthwise extending sides for placement alongside a craft that is to be transported. Wheels on the sides of the frame proximate the open end of the frame provide for the frame to be rolled on an underlying surface and for the frame to pivot relative to the wheels. Lift bars extend from the sides of the frame proximate the open end of the frame, including lifters for engaging a craft, to support the craft on the frame. A handle is at a lengthwise end of the frame opposite the open end of the frame. The lift bars and lifters are constructed and arranged to provide a mechanical advantage for lifting the craft when the handle is forced in a generally downward direction to pivot the frame about the wheels. Various embodiments of lifters are disclosed.
