A wheel-supported transport vehicle which is capable of transporting loads of theoretically unlimited total weight. The vehicle comprises a manned vehicle unit, which embodies a master power unit and master gear transmission system, and a number of unmanned vehicle units, each having its own respective power unit and gear transmission system. The vehicle units are coupled together in a special manner to form a train of said units. The manned vehicle unit is provided with a master operating system, pneumatic circuitry and electrical relay system, which in combination with similar systems and circuits in the unmanned units cause the gear positions selected in the manned unit to be copied contemporaneously in the gear systems of the unmanned units and by which all gears are selected with the same force.
