Load-haul-dump (LHD) machines are a mainstay of any underground hard rock operation. The Komatsu WX03 LHD is a 3-tonne diesel-powered machine designed for small, narrow vein applications with limited maneuvering space. This LHD features simple operation controls and a long-life structure specifically designed for ease of use and ease of maintenance with an onboard self-diagnostic user interface.

With an efficient powertrain and hydraulic system designed for improved performance and an operator compartment with easy-to-use controls, this small-class LHD can offer ideal performance.

Benefits of the Komatsu WX03 LHD

  • 74 kW (99 HP) water-cooled engine for low environmental heat
  • Outstanding breakout power for fast bucket filling
  • Pre-engineered options to suit most applications and requirements

Engineered for reliability, the WX03 is built with a steel frame design and a heavy-duty, all-mechanical powertrain, to help hit production targets while controlling costs. It is designed for long component life with mining-grade components, a proven powertrain, a severe-duty electrical system, and collet-style pins.

Ease of use for operators and maintenance team

To help a mine drive toward zero harm, the WX03 offers multiple features including a ROPS/FOPS-certified enclosure, a spring-applied braking system, operation interlocks, three-point mounting, anti-slip steps, and hot component isolation. With its intuitive controls and ergonomics, this LHD is built for operator comfort and visibility. Easy-to-use two-handed controls simplify training and operation, and the unique bucket geometry is designed to optimize efficient filling with less spillage.

Offering ideal serviceability, the WX03 has vital maintenance components accessible from the ground level that are designed to help service crews make fast, efficient repairs.

Tailor the Komatsu WX03 LHD to specific mining needs

Customizable to meet operational needs, some of the available options on the WX03 include an automatic lubrication system, ejector bucket, fire suppression system, quick-attach coupling system, radio remote control, and recovery hook.
