Liebherr is extending its product offerings with the T 274, a class-leading 305 t / 336 tons haul truck. This new truck bridges the gap between the highly successful T 284 (363 t / 400 tons) and the T 264 (240 t / 265 tons).
Operating the T 274 with other Liebherr Mining products provides the opportunity to achieve the greatest productivity, while minimising operating costs.
The T 274 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.
This new 305 tonne truck can be fitted with the Liebherr Trolley Assist System, a significant step towards zero emission mining.
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.

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.
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.
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.
Pairing the Liebherr T 274 with the Liebherr R 9800 hydraulic excavator provides the customer with highly versatile and productive fleet. The fast swing times of the R 9800 will load the T 274 with 4 bucket passes ensuring quick loading times that lead to high production rates of both the truck and excavator.
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.
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. Customers can be assured the T 274 will be a reliable and highly available truck to add to their mining fleet.
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.

Liebherr is committed to designing mining trucks that operators want to drive. The ergonomic design of the T 274 cab creates a safe, comfortable, and productive environment for operators. The cab provides maximum visibility utilising tinted safety glass windows, and is certified for roll-over and falling-object protection. The integrated HVAC system provides comfort in all temperature extremes. 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 machine access. The ground level maintenance areas provide safe and efficient service access.
Double A-arm suspension keeps optimal ground contact of the tyre within the whole suspension stroke, reducing the tread and wear with optimised camber and toe angle.
These properties of the front suspension system deliver superior comfort, safety, and handling for the T 274 operators improving the ride quality and reducing overall body vibration exposure.
The Liebherr active intelligent control systems provide safety for the operator:
