Liebherr Group has launched its new mining truck, T 274, that bridges the gap between the highly successful T 284 (363 tonne) and the upgraded T 264 (240 tonne).
Designed and adapted from years of experience in mining truck development, the 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. Operators and technicians can expect to experience first-class comfort and safety while driving and servicing this truck, says company.
Based on the proven design of the Liebherr T 284, the T 274 offers the customer an incomparable performance, it states.
“It is powered by the most powerful engine in its class at 3,650 hp, 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,” says a company spokesman. “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.
Pairing the Liebherr T 274 with the Liebherr R 9800 hydraulic excavator provides the customer with a highly versatile and productive fleet. The T 274 is also compatible with the brand new R 9600 excavator, the successor to the thoroughly proven and iconic R 996B.
The T 274 is based on the proven design of the Liebherr T 284, which has gained more than 20 million operating hours in the field.
