Product Features and benefits:
Monitor Efficiency with Payload Data: Utilize Payload Meter IV to boost production by optimizing payload, maximizing cycle efficiency, and reducing life cycle costs. Standard on Komatsu off-highway trucks, PLM IV meticulously tracks carry weight, haul cycles, speed data, and more.
Traction Control for Firmer Footing: Ensure your drivers stay focused and operate efficiently in slippery conditions. The Wheel Traction Control technology detects and corrects wheel spin or slide events independently of the service brakes, providing a firmer footing.
Multiple Advantages of Electric Drive: Opt for electric drive to minimize mechanical components, reduce maintenance, improve truck availability, and lower life cycle costs. This drive system also keeps fuel use low, contributing to a smaller carbon footprint.
Controls Enhancing Driver Awareness: Cruise control manages acceleration and deceleration, allowing operators to concentrate on steering and situational awareness. The simple automotive-style controls enable drivers to easily “set it and forget it.”
Customized for Your Operation: Every truck body is precisely engineered to meet specific application requirements while efficiently carrying its rated payload. Collaborate with us to understand material properties at your mine site and identify the appropriate liner package.
Structurally Enhanced Frame: Durability is paramount when handling significant loads. The truck’s frame, verified through advanced computer-aided design, finite element analysis, and full-scale dynamic testing, ensures it can carry the rated payload with utmost structural reliability.
Promotes a Safe Work Site: Implement multiple technologies, including traction and cruise controls, to help operators maintain a safe working environment.
Multiple Fuel-Reducing Technologies: Maximize engine longevity by using less fuel. The engine and drive systems of Komatsu trucks are precisely tuned to seek efficient power usage while minimizing fuel consumption. This includes optimized air handling with two-stage turbocharging.
Modular Design for More Uptime: The elegant, modular design facilitates quick repair and replacement of major powertrain and hydraulic parts, ensuring routine maintenance is fast and easy, ultimately maximizing uptime.
