Komatsu’s WX03 LHD provides solutions to demanding underground mining environments with a rugged design, manoeuvrability, safety features and various customisation options.

Load-haul-dump (LHD) machines are a mainstay of any underground hard rock operation. Engineered for the most demanding mining environments, the Komatsu WX03 LHD is a 3-tonne diesel-powered heavy-duty machine designed for especially small, narrow vein applications with limited manoeuvring space. This solid LHD features simple operation controls and a rugged 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, as well as a modern operator compartment with easy-to-use controls, this small-class LHD can offer big performance.
