  • Structural

    Frames are fabricated from high strength, low-alloy steel with excellent weld characteristics and extreme low temperature properties. The front axle is an integral, fixed part of the front frame. The rear axle center oscillates 11 degrees.

    Unique forged ball and socket joints are utilized in multiple pivot locations (lift arms, rear axle, frame articulation, hoist cylinders). These joints are superior in absorbing and distributing multi-directional stresses. Features easily replaceable brass liners for long life and easy maintenance.

    High strength castings are used in key areas of fabricated structures to reduce stress and improve structural life.

Powering progress: SR technology

Komatsu’s ties to SR Technology date back to the beginning. SR is the future, but it’s been part of Komatsu’s for a long time. Everything we did has been built on decades of work and experience. Not only can we offer the benefits others are beginning to scratch the surface on, but we know how to apply this technology and optimise every bit of reliability, fuel efficiency and performance.

Kinetic Energy Storage System (KESS)

During propulsion, diesel energy is converted to electricity. Energy flows from the motors and is stored in the KESS unit. During acceleration, the diesel engine and the stored KESS energy generate an additional 550 HPin underground LHDs and 1,100 HPin surface wheel loaders.

MineCare Maintenance Management System

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 utilisation and reduced maintenance costs and equipment degradation.
