Komatsu has introduced an all-new 7-tonne LHD and redesigned 4-tonne LHD, each developed for productivity and longevity at hard rock mines worldwide.
The models were released to the industry earlier this month in a special online event hosted by the OEM.
The WX07 7-tonne model has a whole new chassis, powertrain and operator cabin. Versus others in its same size class, the WX07 performed 15% faster on a grade and is capable of delivering up to 10% more breakout force – making it as much as 14% more productive.
Designed for small and narrow vein mines, the new machine has Z-link kinematics, a reinforced boom, and efficient bucket design. It is engineered to keep minerals loading with a 243-litre fuel tank.
“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,” Komatsu said.
The equipment maker has also released the WX04 4-tonne LHD, which is a renamed and redesigned Joy 4LD.
With a fuel tank size of 190 litres, the model can offer 31% more capacity than its closest competitor, Komatsu said, citing published data, and also 20% greater breakout force than others in its size class.
The WX07 and WX04 are both available for order immediately.
