Rolls-Royce has announced it will supply its Stage V engines to Hellgeth’s latest timber harvester.
The TC 624 tracked vehicle will be powered by the 4-cylinder Series 1000/OM 934 MTU engine and will be used mainly as a forwarder, taking harvested timber through wooded areas to forest roadways for loading on to trucks.
The articulated timber harvester from the German manufacturer is fitted with rubber wetland-compatible tracked drives, which are designed to travel on the rough and uneven forest floor. The machine also has a full-suspension, adaptable drive system able to spread loads evenly on uneven terrain and avoid damaging the ground surface (for example, when driving over roots).
The combination of the MTU engine, a power-split transmission and a full-suspension chassis, enable much higher driving speeds than conventional machines both on- and off-road. The vehicle can reach speeds of up to 40km/h.
The engines also deliver on Hellgeth’s sustainable technology goals. The 4-cylinder Series 1000/OM 934 achieves 170kW of power output and meets the new EU Stage V emissions limits. The engines are known for their low fuel consumption while delivering high levels of torque, making them highly suitable for use in forested areas.
Thanks to its characteristics, the TC 624 is also able to open up poorly accessible areas that remain out of bounds to wheeled vehicles.
