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

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

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

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

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

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

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

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

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

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.

MineCare

The MineCare Maintenance Management System combines the benefits of real-time remote equipment health monitoring with cloud computing technology and advanced analytics capabilities. The MineCare System promotes the advanced detection of issues before they occur, thus helping to reduce unplanned maintenance events, promoting increased uptime and utilization and reduced maintenance costs and equipment degradation.

technology-image

The ProVision Guided Spotting System helps to optimize the loading cycle by presenting truck operators with precise directional guidance via intuitive visual cues when spotting at a loading unit. By helping the operators hit the spot the first time they reverse into position, potentially eliminating the need for a hanging bucket or flag, the Guided Spotting System promotes faster loading times for increased productivity.
