Abstract
An improved auto-chocking enabled cargo dolly that is towable by ground support equipment. The dolly has a frame, wheels attached to the frame that support the frame and rotate to allow movement of the frame, a tow bar, a linkage in communication with the tow bar and that actuates when the tow bar is raised, and a wheel engagement chocking system fixed to the dolly frame and disposed to selectively engage at least one of the wheels attached to the dolly frame. The wheel engagement system is responsive to a position of the linkage, where the wheel engagement chocking system applies pressure directly to at least one of the wheels to hold the wheel(s) in place when the linkage is actuated by the tow bar.
