A cart for transporting a load has a frame having an upper end and a lower end, at least two laterally spaced apart support surfaces secured adjacent the upper end of the frame, and a pair of transversely opposed wheels adjacent the lower end of the frame to rollably support the frame above a surface. Each wheel is positionable in either one of two laterally offset positions relative to the support surface. In the first offset position, each wheel is positioned laterally inboard of the support surface, and in the second offset position, the wheel is positioned laterally outboard of the support surface.
