Every part focused on productivity

Every aspect of this trolley-ready truck is engineered to help reduce your cost per ton. From its incredibly reliable Siemens AC control and liquid cooled Insulated Gate Bipolar Transistor inverter system to its industry-leading build quality, count on it being up to the challenge for years to come even in harsh conditions.

Features may include:

  • Liquid-cooled inverter system
  • Hill start prevents rollback
  • Trolley-ready
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. 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. This includes traction and cruise controls.
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.
