摘要
In a push back cart rack storage system, the top or first cart, as well as the second cart, may be made with less material, and may be significantly simpler and lighter in comparison to existing designs. A push-back cart storage system has a single pair of push-back rails in each lane. A third cart has front and back wheels rolling on a lower inside flange of the push-back rails. A second cart has front wheels rolling on a lower inside cart flange of side rails of the third cart, and has rear wheels rolling on the lower inside flange of the push-back rails. A first or top cart has front and rear wheels rolling on a top surface of the push-back rails. The wheels on the first cart may be inner facing wheels while the wheels on the other carts may be outer facing wheels. The push-back rails and the side rails of the carts may be generally C-shaped channel sections. The top cart and the second cart may be made of angle sections to reduce the weight of the cart and the amount of material needed to manufacture the cart.
