Self-propelled Modular Transporters is the specially designed transportation solution (such as offshore oil platform of combinatorial transportation etc.) for transporting outsize, mega-heavy articles. Modular transporter is compact in structures; and every unit could be combined independently. Furthermore, when adding modules, the whole loading capacity could increase accordingly. Electric control system actualized modularized program control; it is convenient to control the expansion of system. Modular units use CAN-bus communication technology, accurately control the location and action of each wheel, to achieve various steering, circulating function, and integrates a whole system self-diagnostic system, for real-time monitoring and give warning indicates.
