Capable of pulling 500 tonnes, the E4 has twice the pulling-power of its smaller cousin, the 250 tonne capacity Rotrac E2 that made its debut last year.
Using Linde drive technology, unique in the railway technology sector, the small electric rail trolleys can shunt trailers and freight trains in the tightest spaces, making them ideal for tri-modal use in ports, loading stations and shunting operations.
With the Rotrac E2, the amount of torque generated by the electric four-wheel drive and the adjustable contact pressure on the rails due to its moving guide rollers, means that it can tow 250 tonnes without difficulty. When off the rails, the electric four-wheel/live-axle steering enables it to manoeuvre freely on asphalt with a turning radius of only 0.9 metres.
