With a new chassis, powertrain and operator cabin, Komatsu’s brand new WX07 7-tonne LHD has been designed from the ground up to provide a standout experience and environment for underground hard rock mining operators.

Compared to competitors in its size class, the WX07 is 15% faster on a grade and delivers up to 10% more breakout force, making it up to 14% more productive. Engineered for small and narrow vein mines, this machine offers a combination of Z-link kinematics, a reinforced boom and efficient bucket design that enables excellent penetration into the pile for fast bucket filling. The WX07 is engineered to keep minerals loading with a 243-liter fuel tank for longer operational cycles between re-fuellings.

The WX07’s operator cabin is built for visibility and ergonomics, including ample headroom for ease of entry and exit. A design that makes vital maintenance components accessible from ground level means that crews can perform service and repairs without the need to climb or use a ladder to get to key areas.

In addition to the new WX07, Komatsu’s popular Joy 4LD has been redesigned, renamed the WX04 and rebranded as a Komatsu product. A 4-tonne LHD built for challenging narrow vein applications, the WX04’s 190-liter fuel tank offers 31% more capacity than its closest competitor, based on published data. The WX04 also offers 20% more breakout force than any machine in its size class.

“We’re excited to add the WX07 and WX04 to our LHD lineup, which now has a capacity that spans from 3 to 22 tons,” said Bill Maki, product manager for Komatsu’s LHDs. “No matter what class of LHD your operation needs, Komatsu offers a choice of machines to consistently haul your ore efficiently and effectively.”

The WX07 and WX04 are both available for order immediately.
