T 274 - Liebherr

T 274

Where innovation meets a tried-and-tested design

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.

Innovative design and technologies powering the T 274

User-centric design

The safety and comfort offered by the T 274 makes driving and servicing a first-class experience. The double A-arm suspension improves tyre-to-ground contact, leading to reduced tyre wear and a smoother ride experience. And thanks to the rear axle, the axle box and tyres receive in-line forces from the dump body with no bending or warping, lowering machine failure rates.

Easy maintenance

The T 274 has been designed for easier maintenance and faster servicing. To improve accessibility for service personnel, its central service station is located on the fuel tank and its refill and drain points can be reached from the ground thanks to their fast couplings and depressurised valves.

Litronic Plus AC Drive System

The T 274 has a diesel-electric drive system, called the Litronic Plus AC Drive System, rather than a mechanical drive system. It was designed, developed and built by Liebherr to maximise the amount of electrical power converted into mechanical torque for faster truck acceleration and reduced energy consumption.

Vertical integration

All Liebherr mining trucks are equipped with Liebherr’s Litronic Plus AC Drive System as well as the company’s D98 series of internal combustion engines. The full vertical integration of the powertrain provides with unprecedented flexibility and the ability to customise the T 274 to fit their unique mining needs.

Autonomous Haulage Solution

Liebherr’s Autonomous Haulage Solution (AHS) combines cutting-edge automation technology with real insights to enhance productivity, safety and efficiency.

The autonomous platform has been designed with the future in mind and is compatible with both diesel-electric and zero emission energy systems. The AHS can be integrated with the Energy Management System from Liebherr’s Fleet Management System to orchestrate the energy replenishment of Liebherr’s zero emission mining truck.

Dynamic Power Transfer

Liebherr currently offers two different kinds of dynamic power solutions for its mining trucks: the Trolley Assist System and Liebherr Power Rail.

Trolley Assist System

The Trolley Assist System uses an overhead pantograph to connect the trucks’ electric-drive system to the mine’s electrical network, lowering fuel consumption and raising speed on grade.

Liebherr Power Rail

Liebherr Power Rail is a class-agnostic dynamic power concept based on the company’s existing trolley bar technology, utilising a bar mounted on the side of the truck. This solution is designed to be easy to install and to relocate on site.

*Site-specific factors like loose material density, bucket size, fill factors, truck body size and payload capacity will influence pass match. Contact your local Liebherr sales and service company or sales partner for analysis of your site.

The perfect Liebherr pairing

The T 274 is the powerhouse of the 305-tonne class and is a perfect pass match for R 9600 and R 9800 excavators. This mining truck is designed to thrive in a wide range of applications and provides maximum productivity, even in the harshest conditions. It especially thrives in large deep-pit applications where its high power-to-weight ratio results in fast cycle times.

R 9600

Liebherr’s R 9600 and the T 274 truck form a formidable team, driving productivity in modern mining operations. The R 9600, the undisputed leader of the 600-tonne class, offers unmatched performance with its industry-leading bucket capacity, fuel efficiency improvements of 20% compared to its predecessor, and an impressive service life of over 80,000 hours. Paired with the T 274, this combination maximises both efficiency and performance.
