This cart is the result of a request from a Aerospace customer for an ultra-heavy duty cart that can transport a 20' ISO container or a smaller 12' non-ISO container along with a generator. The cart must be off-road capable and be able to resist the forces presented by rough terrain. The load maximum of 16,000 lbs along with the cart weight of 7000 lbs. is supported by four foam filled 7260 lb casters with face contact wheel brakes.
