LHD

WX04

  • Tramming capacity 4 000 kg 8,800 lbs.
  • Bucket 1.9 m³ 2.5 yd³
  • Height to top of canopy 2 073 mm 80 in

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.

  • 20% more breakout force of any machine in its class*
  • 26% faster operating speed with loaded bucket**
  • 14% more productive than the competition***
  • *Breakout force is based on a comparison of published competitor information of similar LHDs in the 4-tonne class
    **Operating speed measured with loaded bucket on grade, based on published competitor information
    ***Productivity increase based on a detailed competitive comparison with other 4-tonne loaders in its class (data available on request)

Features and benefits

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.

Best-in-class operator cabin

Operator cabs are ROPS/FOPS-certified with generous space and comfort. A fully enclosed, environmentally controlled option includes open-door safety interlocks that activate brakes while deactivating the boom, bucket and steering functions.
