ABSTRACT:
An object or vehicle transporting dolly supporting one elevated object end comprising of a pair of mounting pads and transporting wheels each connected to a pair of vertically pivoting control arms which have also a vertical pivot connection to a center parallel control member which then can be fixed to a draw and steering control tongue. The scissoring control arms provide for handling multiple widths of objects. A frame connection rack or a wheel well for dollying of wheeled vehicles can be fixed to the mounting pad and can optionally swivel on the mounting pad. Articulation between the towing and towed vehicles force the tongue and control arms to direct the mounting pads and the trailering wheels to maintain a longitudinal alignment to the draw control tongue, even though they are in a fixed longitudinal position to the transport object causing king-pin type of steering with the swivelling at the mounting pad. With the use of a "v" draw tongue pivoting at the wheel pads, the dolly can be towed in a castering mode. Without the use of the draw control tongue or the swivelling mounting pads, this dolly can be used to transport the elevated rear of an object or vehicle. Multiple dollies can be interconnected and optionally framed for one end up or complete object trailering with rear wheel steering as an option.
