    BUCKET CAPACITY

WX04 Underground hard rock haulage

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.

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.

Structural integrity

Komatsu's Z-link, reinforced boom design, and optimised geometry offer your mining operation the fastest boom cycle time in its class, excellent reliability, durability and productivity.
