A cart for transporting material has wheels located intermediate to end wheels, the intermediate wheels extending downwardly a greater distance than the end wheels so that the cart may tilt and may be turned around the intermediate wheels. The wheels may be mounted on flanges depending from a frame of the cart, the flanges serving to protect the wheels and serving to support the cart in the event of a wheel failure. The cart may have a pair of wheels located intermediate to the end wheels so that traversing uneven terrain is improved and eased, and so that the intermediate wheels serve as backups to each other. The intermediate wheels may be a same or similar size, though mounted lower on the flanges, than the end wheels. The intermediate wheels may be larger than the end wheels.
