Self-propelled modular transporters (SPMTs) are multi-axle trailers designed for the transportation of large and heavy cargoes. The SPMTs are designed in modular construction and can be coupled side to side and end to end, or remote units can be operated as a single transporter via radio controls. The SPMTs consist of a very strong and rigid chassis, which also acts as a load-carrying platform to which wheel bogies are attached in pairs to form the required length of transporter. Each wheel bogie consists of two rubber tyred wheels and is rigidly fixed to the chassis by a hinged elbow joint, which is supported on hydraulic rams. This hydraulic ram acts as the suspension for the SPMT and also provides the lifting capability. Attached to the end of the SPMT is a Diesel driven power pack, which provides hydraulic power to the various functions of the SPMT.

The steering of the SPMT's offers major advantages over other forms of conventional hydraulic trailers. This offers total flexibility of steering options with each wheel bogie able to swing through 260° (+130°). The position of each wheel is controlled electronically through the remote operations console and nine steering programs are available.
A transporter convoy, composed of transporter units and power packs can be controlled by a single operator by means of the hand operated remote console. All units are both CE and TUV certified and are provided with identification plates that allow them to be driven on public roads.
