A cart for supporting pallets weighing over 2000 lbs and even over 3000 pounds and transporting those pallets on rails is provided. The carts are formed by releasably attaching a minimal number of pieces, such as by bolting the parts together. By making the parts substantially identical and making the parts as symmetric mirror images, a single part can have multiple uses, such as on both the left and right sides or both the front and back. For example, a rear cross beam can have the same dimensions as a middle cross beam and/or a front cross beam. A left side beam can be identical to a right side beam. A right side bracket for connecting beams and/or mounting wheels can be identical to a left side bracket and a front bracket can be identical to a rear bracket.

A raisable and lowerable storage system is provided comprising a steel container with multiple compartments, a scissor lift device attached to at least a bottom area of the container, wheels attached to a lower area of the scissor lift device. The scissor lift device raises and lowers the container to a desired level. The scissor lift device raises the container to a maximum height of about eight feet. The wheels support the container as the container is placed into a bed area of a vehicle for transportation. The wheels roll along tracks attached to the bed area of the vehicle. The container is secured before the vehicle begins moving to prevent the container from rolling about as the vehicle moves. A battery in the container is charged while the container is in a secured position and the vehicle moves.
