Liebherr T 282 C: Update of the world’s largest and most efficient mining truck
At the 2010 Bauma, the new ultra class mining truck T 282 C will be shown in public the first time. With an empty vehicle weight (EVW) of 236 metric tons (266 tons), the T 282 C can carry a payload of up to 363 metric tons (400 ton). Available engine options for the T 282 C include the MTU DD 20V4000 (20-cylinder / 2,800 kW / 3,755 hp) or the Cummins QSK 78 (18-cylinder / 2,610 kW / 3,500 hp). Its top speed is 64 km/h (40 mph). With the first pre-series units already in testing and the official product release being scheduled for the fourth quarter of 2010, the T 282 C builds upon the performance of its predecessor and provides improvements that minimize downtime and maximize production. The new frame, axle box, cabin, IGBT AC drive system, Liebherr Vertical Integration and Load Management Design Philosophy will increase performance and provide a designed reliability in the T 282 C. This culminates in a truck with superior performance and reliability, ultimately providing the end-user with the lowest possible cost per tonne.
The innovative drive system with IGBT frequency inverters is of completely desiged and manufactured in-house at Liebherr. Together with the Liebherr regulating system, the liquid-cooled IGBT power modules optimise control of the traction motors. The frequency inverters for auxiliary equipment are supplied with electrical energy regenerated, if circumstances permit, when the vehicle is braked. The new system includes wheel motors and planetary gear sets developed by Liebherr. It guarantees that the diesel engine runs independently of travel speed and its fuel consumption can therefore be optimised. The only deciding factor is the performance called for in any particular application.
