Unimog U 423 professional implement carrier
and shunting vehicle.

Exhibit InnoTrans 2022.

Professional implement carrier and shunting vehicle on the railroad.

  • This vehicle is a combination of shunting vehicle and implement carrier due to the installation of G31 (torque converter clutch) and G34 (hydrostatic travel drive)
  • Optimal working speed due to EasyDrive (hydrostatic drive)
  • Possibility of towing heavy weights, for example: broken-down trams with the assistance of the torque converter clutch
  • Fire alarm and fire extinguishing system in engine compartment (fire protection certificate TÜV Süd Rail)
  • Use of numerous quickly interchangeable implements / superstructures – Mulag front power arm, Palfinger loading crane, Zweiweg aerial platform, Dammann track spraying system, Kahlbacher snow plow and Zweiweg road-rail trailer.

More information on the road-rail Unimog.

The Unimog manoeuvres in road-rail operations with a high tractive force of up to 1,000 t towed load. This is possible thanks to the torque converter clutch, permanent all-wheel drive, compact axles and drive via the truck’s own wheels. The fully-fledged rail vehicle is flexible at all times thanks to the quick transition between rail and road – not least because the Unimog is full of possibilities that go far beyond shunting: Its attachment and body mounting spaces as well as the mechanical, electrical and hydraulic interfaces make it ideal for a wide range of tasks in the maintenance and repair of the rail infrastructure.
