Liebherr T 274 haul truck has a capacity of 336 tons. It’s a new model, fitting between the 265-ton T 264 and the 400-ton T 284.
The Liebherr T 274 haul truck is powered by an 3,650-horsepower Liebherr Litronic Plus AC Drive system. The Liebherr Litronic Plus AC Drive System provides continuous uphill speed. It has 6,035 horsepower dynamic braking power for downhill hauls.
The rigid-frame haul truck matches up with the Liebherr R 9800 and Liebherr R 9600 mining excavators. The R 9800 will load the Liebherr T 274 with four bucket passes.
The cab provides visibility utilizing tinted safety glass windows and is certified for roll-over and falling-object protection, and it has two safety exit routes from the cab to the ground. Ladders and platforms provide engine access, and ground level maintenance areas are designed to be safe and efficient, according to the company.
Double A-arm suspension keeps optimal ground contact of the tire within the whole suspension stroke, reducing the tread and wear with optimized camber and toe angle.
The Liebherr Trolley Assist System is available as an option as an effective first step on the road to zero emission mine sites, according to the company. Utilizing an overhead pantograph to connect the electric-drive system to the electrical network, the Trolley Assist System can either increase truck fleet productivity, or reduce the fleet size while maintaining yearly production, when compared with standard trucks. The main advantage is the significant reduction of diesel fuel consumption and truck fleet CO2 emissions.
