Improved multifunction performance

The intelligent load sensing hydraulic system analyse operator input and load to improve multifunction performance with efficient power distribution in each pumps and smooth priority shift transition resulting to increased machine productivity.

Powerful digging operation

Digging force has become more powerful with the higher engine power output coupled with high capacity pump and efficient hydraulic system feeding the redesigned Komatsu hydraulic cylinders.

Operator cab specially designed for mining

Operator cab provides a comfortable working environment. Sturdy cab of solid construction, with top guard  compliant to OPG level 2 (ISO 10262).
