LHDs you can rely on to drive productivity and performance

Based on the 4LD legacy, the new and redesigned WX04 is a reliable 4-tonne LHD for narrow vein applications. The WX04's high-strength steel frame design with heavy-duty, all-mechanical powertrain can help you hit your production targets while keeping your costs down.

Features may include:

Stage V low-emission engine
  • This low emission engine option of the WX04 offers all the power and performance benefits, along with low emissions for regions that can use ultra-low sulfur fuel.
Ground-level maintenance design
  • Get exceptional serviceability with vital maintenance components accessible from the ground level. Ensure fast, efficient repairs with added protection for your service crew.
Highest breakout force
  • With the highest breakout force in this size class, 20 percent greater than the closest competitor, you can rely on the WX04 to fill the bucket quickly for faster cycle times.
Unmatched nonstop operation
  • With a larger 190-liter fuel tank, you'll be able to have longer operational range without having to stop and refuel. Benefit from 31 percent greater non-stop operation (versus other leading LHD machines in the 4-tonne class).
Structural integrity
  • Komatsu's Z-link, reinforced boom design, and optimized geometry offer your mining operation the fastest boom cycle time in its class, excellent reliability, durability and productivity.
