Liebherr has released the T 274 haul truck with a class-leading 305-tonne payload capacity.
The T 274 is designed to fit between the Liebherr T 284 and T 264 haul trucks, offering fast cycle times, high production and reduced fuel costs.
The T 274 features the largest payload capacity in its class and is powered by a 3650-horsepower engine and Liebherr Litronic Plus AC Drive system allowing the machine to move material in shorter times.
It also features 6035-horsepower dynamic braking power which allows the truck to operate efficiently on downhill hauls.
Liebherr has designed the T 274 to work across harsh environmental conditions with a wide range of options available to suit bespoke applications and demands of mine sites.
Based on the 400-tonne T 284, which has achieved more than 20 million operating hours, the new mining truck brings reliability and a long history of field experience.
Liebherr has designed the T 274’s cab with an ergonomic design to provide maximum comfort and safety for operators, enabling high levels of visibility through tinted safety glass windows.
The cabin is also certified for roll-over and falling-object protection, with two safety exit routes from the cab to the ground.
The T 274’s reliability is enhanced by its double A-arm suspension which allows for the right amount of ground contact of the tyre within the suspension stroke, which reduces tread and wear with its optimised camber and toe angles.
“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,” Liebherr stated.
The Liebherr Trolley Assist System is one of the options available on the T 274, which acts as a first step to achieving zero emission mine sites. Liebherr uses an overhead pantograph to connect the electric-drive system to the electrical network.
“The main advantage is the significant reduction of diesel fuel consumption and truck fleet CO2 emissions,” Liebherr stated.
