Abstract

A ramp assembly for use with a wheeled cargo transportation cart comprised of a frame, wheels for rolling engagement with a support surface, and with cargo ramp assemblies attached to either end of the frame. The cargo ramp assemblies pivot under the weight of cargo, between a engagement position for loading and unloading of cargo, and a storage position for storage. The cart also is comprised of handles removable engagable with the frame, to allow for movement of the cart in any direction. An adjustment member is in rotatable engagement with the frame allowing for selective adjustment between a locked position thereby preventing rolling movement of the cart, and unlocked position thereby allowing rolling movement. The adjustment member is further engaged with locking elements such that when the adjustment member is in the locked position friction surfaces of the locking elements contact the support surface thereby prevent rolling movement of the cart on the support surface, and when the adjustment member is in the unlocked position the friction surfaces of the locking elements are held at a distance from the support surface to allow rolling movement of the cart.
