Low profile push-back cart and push-back cart storage system
A push-back cart storage system has one or more push-back carts having a cross-member formed by a structural angle section having cutouts at opposite ends to provide clearance for the second push-back cart to move under the first push-back cart. The cross member provides a truss or joist type of beam support having a full height middle section which resists bending and a reduced height at the ends, to provide a low profile. Side members or angle sections on the cart have through holes for attaching wheels, with no welding of wheel mounts required.
