Abstract
A transport device for hauling a load having a front axle with a pair of wheels and a rear axle with a pair of wheels. Four vertical hydraulic cylinders are provided, each cylinder having a bottom end supported on one of the axles adjacent a wheel, respectively. A pair of yokes is provided. Each yoke has one end supported by the ram extending from the top of one cylinder mounted on the front axle and the other end supported by the ram extending from the top end of a cylinder on the rear axle so that the yokes are parallel to one another and extend form front to rear of the device. A container containing the load is suspended from the pair of yokes. In one version, the device is coupled for transport to a truck. In another version, an engine is mounted on a cantilever frame extending from the rear of the truck controlled by operators in a cab mounted on the front end of the device. In another version, the device has a tongue extending from the front axle and attachable to a truck tractor.
