InnoTrans 2024 | Unimog U 423
Cost-efficient shunting up to 1,000 t.
The Unimog road-railer has a high tractive force and can tow a trailer load of up to 1,000 t. This is possible by the torque converter clutch, the permanent all-wheel drive, compact axles and the drive via its own wheels. By quickly switching between rail and road, the fully fledged rail vehicle can be used flexibly at any time - not least because the Unimog is full of options beyond shunting: its attachment and body areas as well as the mechanical, electrical and hydraulic interfaces make it ideal for a wide range of applications in the maintenance of the rail infrastructure.

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.
