Liebherr’s New 305t Mining Truck – The T 274

Liebherr is extending its product offering with the T 274, a class-leading 305t / 336 US tons haul truck. This new truck bridges the gap between the highly successful T 284 (363t / 400 US tons) and the upgraded T 264 (240t / 265 US tons).

Designed and adapted from years of experience in mining truck development, the T 274 is a true 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. 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 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. 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.

 

Liebherr R 9800

Pairing the Liebherr T 274 with the Liebherr R 9800 hydraulic excavator provides the customer 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 brand new R 9600, 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. The frame and components are shared between both the T 284 and the T 274. Liebherr’s solid reputation as a reliable Original Equipment Manufacturer (OEM) stems from consistent development and production of high-quality mining components, products, and services. The T 274’s mining-optimised components are developed, manufactured, and controlled by Liebherr following our vertical integration model to ensure top performance and reliability for the entire machine.
