The Unimog Dual-mode Road-Railer

Mercedes-Benz Econic 1828 LL vehicle for overhead-line installation

The road railer version of the Mercedes-Benz Econic has a low-floor cab, enabling easier access and egress at construction sites. The vehicle features a dual-axle hydrostatic drive system with an axial piston-type variable-displacement pump for operations on metro or tramway lines with small curve radii. The Econic can be operated from the platform and also features an extended cab with an integrated workshop area.

Three Unimog road-railer models are on display at the Zagro/Zwiehoff stand:

U 400 shunting vehicle

This is a shunting vehicle equipped with a torque converter clutch, a waggon brake system for 52 axles (max. 800 tonnes), an automatic coupling rod with lifting device, a UIC coupling head and a camera system for easy on-tracking including illumination of the rail guidance system.

U 400 recovery vehicle

This Unimog U 400 can be employed for operations such as rerailing derailed waggons. It features a box body with integrated crew compartment and sufficient stowage capacity for necessary tools. The rerailing system includes a hydraulic assembly driven by the Unimog's front PTO shaft as well as various lifting cylinders and rerailing bridges. Spreaders, cutting and welding equipment, floodlights and a three-phase generator are available for rescue operations. The ability to approach the operating site by road and carry out on-tracking practically on the spot make the Unimog road-railer the ideal choice when time is of the essence.
