Liebherr releases new 305-tonne mining truck with high production rates, low fuel consumption

Liebherr releases new 305-tonne mining truck with high production rates, low fuel consumption

The Liebherr T 274 is a 305 tonne machine that provides fast cycle times, higher production rates, low fuel consumption, and a low cost per tonne. 

This new truck follows the same base design as the T 284, benefitting from its decades of field experience. A wide range of options are available, not only providing maximum productivity in harsh conditions, but also catering to the evolving requirements of customers and mine sites.

The Liebherr T 274 is powered by a 3,650 horsepower engine and the efficient Liebherr Litronic Plus AC Drive system. With the advanced hydraulic design and fast cycle times, the T 274 moves more material in less time. This new addition to Liebherr's mining product range offers a truck with the largest payload capacity in its class, moving more tonnes each hauling cycle.

Speed on grade is a major contributor to fast cycle times. The Liebherr Litronic Plus AC Drive System improves cycle time efficiency by providing continuous uphill speed, differing from traditional mechanical drive trucks that require shifting of gears. Designed with safety in mind, the T 274 is equipped with 4,500 kW / 6,035 HP dynamic braking power to operate efficiently on downhill hauls.

User-centric design

The ergonomic design of the T 274 cab creates a safe, comfortable, and productive environment for operators. The cab provides maximum visibility utilizing tinted safety glass windows, and is certified for roll-over and falling-object protection. The integrated HVAC system provides comfort in all extreme temperatures.

All Liebherr trucks offer at least two safety exit routes from the cab to the ground. Liebherr mining trucks are equipped with ladders and platforms that allow easy engine access. The ground level maintenance areas provide safe and efficient service access.

The T 274 is equipped with double A-arm suspension, which keeps optimal ground contact of the tire within the whole suspension stroke, reducing the tread and wear with optimized camber and toe angle. These properties of the front suspension system deliver enhanced comfort, safety, and handling for the T 274 operators improving the ride quality and reducing overall body vibration exposure.

Versatile for all applications

Liebherr offers an array of specific solutions for customers working in extreme environments. These packages guarantee that the T 274 will be fit for any working conditions. Specific solutions have been created to protect the components and help customers operate machinery in temperatures as low as 40°C/F. 

Liebherr also offers a solution to enable the trucks to be operated at altitudes between 3,500 and 5,000 m / 11,500 and 16,500 feet above the sea level, and a sound attenuation package to reduce truck noise emissions drastically. This ultra-quiet option gives customers the flexibility to run operations day or night, without disturbing nearby residential areas.

First step toward zero emissions mining

The Liebherr Trolley Assist System is available as an option on the T 274. This solution is an effective first step on the road to zero emission mine sites of the future. 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.
