Abstract: A portable ramp for non-wheeled cargo such as, but not limited to, a personal watercraft, designed to assist the movement of cargo in and out of a truck or trailer bed. The invention is both light weight and collapsible for easy portability and stow ability. The invention consists of a composition of parts that facilitate quick assembly and disassembly. A plurality of square hollow tube rails, a plurality of center masts, a connection sleeve and a plurality self-braking wheels assist in the conveyance of cargo uphill with free spinning wheels and slow the cargo's movement downhill by engaging the wheels into a friction pad. The invention uses a wire cable that runs along the bottom of the said rails to strengthen the assembled ramp. This wire cable has adjustable tension and is engaged by extending the center mast downward creating a triangle shape.
