Every part focused on productivity

Every aspect of this truck is rigorously engineered to help reduce your cost per ton. From multiple innovative fuel-saving features to industry-leading build quality and longevity, count on it being up to the challenge for years even in harsh conditions.

  • Optimized weight
  • Tier IV certified engine
  • Automotive-style operator cab

Features and benefits

Monitor efficiency with payload data

Payload Meter IV can help you increase production by optimizing payload, maximizing cycle efficiency and reducing the life cycle costs of your machine. Standard on Komatsu off-highway trucks, PLM IV tracks carry weight, haul cycles, speed data and much more.

Traction control for firmer footing

Help your drivers stay on task and operate efficiently even in slippery conditions. Wheel traction control technology detects and corrects wheel spin or slide events and operates automatically and independently of the service brakes.

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.

Controls help improve driver awareness

Cruise control governs both acceleration and deceleration, allowing operators to concentrate on steering and situational awareness while maintaining a constant speed. Using simple automotive-style controls, drivers can “set it and forget it.”

Customized for your operation

Every truck body is stringently engineered to meet the requirements for a specific application while carrying its rated payload. We’ll work with you to understand the material properties at your mine site and identify the appropriate liner package.

Structurally enhanced frame

When cycling through big loads, durability is everything. Created using advanced computer-aided design, finite element analysis, and full-scale dynamic testing, the truck’s frame has been verified to carry rated payload with utmost structural reliability.

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 optimized air handling with two stage turbocharging.

Modular design means more uptime

Elegant, modular design throughout helps keep your truck on the job by enabling quick repair and replacement of major power train and hydraulic parts and making routine maintenance fast and easy.
