A custom engine transport rack built to hold three engines per unit. Each rack stacks loaded for vertical density during shipment and storage, allowing the customer to maximize engines per truck or container. The corner legs are collapsible. Once the engines are removed at destination, the legs fold flat against the deck, dropping the empty rack to a low profile. Multiple empty racks then nest onto a single return load, dramatically cutting the cost and footprint of getting empties back to the source. A clean solution to the round-trip math that drives every returnable packaging program: load it dense going out, ship it flat coming back.
