Liebherr launches 305t mining truck

New T 274 offers fast cycle times and higher production with low fuel consumption

Liebherr has launched its new dump truck, the T 274, a 305t machine that offers low fuel consumption and low costs per tonne while enabling faster cycle times and higher production.

Describing the new introduction, Liebherr said in a statement that the T 274 is based on the company’s popular T 284 dump truck which has gained more than 20 million operating hours in the field. The new T 274 is also a perfect match with Liebherr’s mining excavators R 9800 and R 9600 and offers versatile solution for all applications, including extreme cold climate and high-altitude environments. It is also available with the Liebherr Trolley Assist System option to reduce fuel consumption and CO₂ emissions.

The new 305 t Liebherr T 274 bridges the gap between the 363t-capacity T 284 and the upgraded T 264 with 240t capacity, said the company’s statement, which added: “Designed and adapted from years of experience in mining truck development, the T 274 is a true 305t 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. Operators and technicians can expect to experience first-class comfort and safety while driving and servicing this truck. A wide range of options are available, not only providing maximum productivity even in the harshest conditions, but also catering to the evolving requirements of customers and mine sites.”

The Liebherr T 274 is powered by a 3,650hp engine, and Liebherr’s Litronic Plus AC Drive system. Speed on grade is a major contributor to fast cycle times while the 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. The T 274 is also equipped with 6,035hp dynamic braking power to operate safely and efficiently on downhill hauls.

According to Liebherr, pairing the T 274 with the company’s R 9800 hydraulic excavator provides customers with a highly versatile and productive fleet. The fast swing times of the R 9800 will load the T 274 with four bucket passes ensuring quick loading times that lead to high production rates of both the truck and excavator. The T 274 is also compatible with the new R 9600, the successor to the R 996B
