The Unimog Dual-mode Road-Railer

This Unimog road-railer boasts an access platform with a working radius of 6.5 metres and can be operated up to a height of 10 metres without requiring additional support legs. The vehicle can also be operated from the platform using the Unimog’s hydrostatic drive system. A special feature of this vehicle is the hydraulic turntable which makes it possible to access the rails even at non-embedded rail sections. The vehicle is positioned perpendicular to the track, raised using the lifting device of the turntable, rotated through 90° and then lowered onto the track with the guide wheels extended.

U 400 working and shunting vehicle

This Unimog U 400 road-railer is equipped with a guidance-bogie – a track guidance system which pivots at the centre of the axis with a guide wheel in front of and behind each Unimog wheel – for coping with very small curve radii. The Unimog also features an inductive train control system (Indusi), a "dead man's handle" and a mobile railway radio telecommunications system (Mesa). It holds certification in compliance with EBO (German railway construction and operating regulations) and BOStrab (German regulations governing operation of light rail transit systems). The crane superstructure, coupling rod and waggon brake system make this a truly all-purpose vehicle.

Two Unimog models and a Mercedes-Benz Econic are on display at the Zweiweg-Schneider stand:

U 400 shunting vehicle with buffer frame

The buffer frame of the Unimog U 400 shunting vehicle completely absorbs impacts from waggons at a speed of up to 5 km/h and a weight of up to 300 tonnes. Therefore it is also suitable for shunting waggons carrying liquids as it allows optimum absorption of the forces created by the sloshing fluid in half-empty tanks. The buffer frame enables the Unimog road-railer to be positioned in the middle of a train. In spite of the attachments for rail use, the vehicle is still highly suitable and officially approved for road use.

U 400 3-axle vehicle for overhead-line maintenance and railway construction

The Unimog U 400 with a rigid trailing axle has an increased permissible gross vehicle weight of 16.5 tonnes. The second rear axle can be hydraulically locked to enhance stability. This Unimog features a railway waggon brake system for 400 tonnes (24 axles). The loading crane superstructure (PK 16502) has a range of 6.1 to 12.6 metres, four-strut support with supporting-leg monitoring, a swivelling-range limiter and radio remote control. The working basket is designed for two persons and equipment weighing up to 300 kg.
