A control lever is pivotably mounted on the body above of the main wheels, and has contact means disposed radially outwardly of the main wheels for contacting a floor to function to function as a fulcrum when the control lever is turned downwardly, for lifting the body and the main wheels off the floor through the leverage of the control lever. The cart even when carrying a heavy cargo can be moved up and down a stair by a single user.
