  • 338,075 kg
  • 186,000 kg

Promotes a safe work site

Multiple technologies help your operators maintain a safe working environment. That includes not only traction and cruise controls, but also KomVision, an optional monitoring system that uses six cameras and eight radars to create a 360-degree view of the area around the truck.

Multiple fuel-reducing technologies

The less fuel you use, the longer your engine lasts. That’s why the engine and drive systems of Komatsu trucks are specifically tuned together to seek efficient power usage while minimizing fuel consumption, including optimised air handling with two stage turbocharging.

Multiple advantages of electric drive

Electric drive means fewer mechanical components and less maintenance, which can help improve truck availability and lower life cycle cost. With the Tier 4 certified diesel engine, electric drive also keeps fuel use low and contributes to a smaller carbon footprint.
