Built with the same frame and many components as Liebherr’s 400-ton (363-metric-ton) T 284 mining truck, the new 336-t (305-mt) T 274 builds on a proven design and bridges a gap in Liebherr’s mining truck lineup between the T 284 and the recently upgraded T 264, a 265-t (240-mt) hauler. Liebherr says the new T 274 delivers both the most powerful engine (3,650 horsepower; 2,720 kilowatts) and the largest payload capacity in its class, allowing mining operations to move more tons with each hauling cycle. The T 274 also pairs well with other Liebherr mining equipment, such as the R 9800 hydraulic excavator that can load the T 274 with four bucket passes, to optimize hauling cycles.

Adaptable To The Environment

Liebherr offers the T 274 in packages made to fit specific, extreme working conditions. One such package allows the mining truck to operate at altitudes from 11,500 to 16,500 feet (3,500 to 5,000 meters) above sea level, while another is designed to protect the components and let the T 274 operate in extreme cold, to temperatures as low as -40 degrees C/F. Liebherr also offers an ultra-quiet, sound attenuation package to reduce noise for operations running day or night near residential areas.

Optional Trolley Assist Cuts Fuel Use

Customers can configure the T 274 with the optional Liebherr Trolley Assist System. Similar to the design of an electric train or bus, Liebherr adds an overhead pantograph for connection to an electric network. Liebherr says the Trolley Assist System stretches the intervals between refuelling, which helps increase fleet productivity, while reducing diesel fuel consumption and carbon dioxide emissions. The manufacturer says 38 T 284 units on two jobsites are already fitted with and using the Trolley Assist System.
