Road/Rail electric shunter ROTRAC E2 and his stronger brother ROTRAC E4
G. ZWIEHOFF GMBH – A SYNONYM FOR HIGH PERFORMANCE AND INNOVATIVE CAPACITY IN THE FIELD OF ROAD/ RAIL TECHNOLOGY 22
The task of the ROTRAC E2 (shunting capacity up to 250 t) and the Rotrac E4 (shunting capacity up to 500 t) is to haul locomotives and railcars at locations like unloading docks, harbours, private railroad companies and repair workshops. Two main requirements of these application areas are very high tractive force of the shunting vehicles as well as their capability of leaving the track and travelling distances between tracks on asphalt. The rubber-coated drive wheels of the ROTRAC E2 and ROTRAC E4 run on the rails and provide the vehicle’s drive, while the lateral guide on rail is achieved by means of metal rollers. The four fully synchronized single-wheel drives are controlled by means of two control units (one per axle) that function in master-slave mode. The key features of the ROTRAC E2 and ROTRAC E4 include a high starting torque, four-wheel drive with electric drive system technology from Linde Hydraulics
