The Self-Propelled Modular Transporter (SPMT) is a platform vehicle with modules of four, five or six axle lines. The modules can be connected to multi-wheel transporters to transport a load that is too big or too heavy for a truck or low-loader. A SPMT can rotate around its centre to make a 360° turn (carrousel) and can move sideways. Each SPMT axle can carry up to 40 metric tonnes, including its own weight. The modules fit on a normal truck. A separate power pack drives the (connected) module(s) and supplies hydraulic pressure for the steering, driving and height adjustment of the modules.
