Lots to love about the Liebherr T 284

Relatively lightweight but strong and nimble, the Liebherr T 284 mining truck is a winner when it comes to productivity and efficiency.

The T 284 builds on the success of Liebherr's earlier T 282 C, retaining its crown as the lightest (lowest empty vehicle weight) and most capable (highest payload) ultra-class mining truck, while reducing fuel consumption. One of the key advantages of this improved machine is its ability to to meet production targets faster, or with fewer trucks.

Built with a 3,000 kW engine, the T 284 is capable of hauling up to 375 metric tonnes, with a gross vehicle weight (GVW) of 612 metric tonnes.

With its advanced hydraulic design and fast cycle times, the T 284 moves more material in less time, optimising the return on investment for customers. Buyers can choose from multiple engine recommendations to find the most fuel-efficient option for a specific mine.

There are other cost-saving features too:

• The T 284's variable hydraulic systems lowers parasitic energy losses, reducing fuel consumption when power isn't needed.
• Electrical power is converted into mechanical torque with the T 284's Litronic Plus Drive system, allowing for higher rim pull forces that enable faster cycle times and increased fuel economy.
• Engine power to auxiliary components like pumps, fans and motors is only supplied when needed. Intelligent power usage means that fuel is conserved when the engine is idling, but that it's up to the job when the machine needs more grunt to accelerate and climb grades.
• Maintenance can be quicker, thanks to ground-level service points and strategically located sight glasses. This easy access means the vehicle spends less time being serviced in the workshop and more time delivering results on the job.
• Liebherr designs its components to last. Longer lasting components means fewer time-consuming and costly overhauls.

In terms of comfort and safety, the T 284 is also a hard worker. The ergonomically designed cab has an integrated HVAC system to moderate temperatures in any conditions, and is certified for roll-over and falling-object protection. An innovative advanced Traction Control System delivers better stability and steering, protecting the driver and its operator even in the toughest terrain.

Other safety features to keep mining operations safe include:

• payload overload warnings
• an anti-rollback feature that works both when reversing and travelling forwards
• certified steering and braking accumulators
• high-vis LED running and service lights
• engine shutdown switches in the cab and at ground level
• ladders, platforms and low working heights for maintenance areas allowing safer access for operators and service personnel.

Liebherr is a reputable brand that consistently develops and produces quality strategic mining components, and the T 284 is no exception. Optimised for mining, its components are all developed, manufactured and controlled by Liebherr, reflecting the German company's high standards.
