1. Growing Demand for Deep-Hole Mining
Entering 2026, the global mining industry faces unprecedented challenges. With increasing demand for key minerals such as copper and iron ore, mining operations are pushing deeper underground. This means that ultra-large excavators like the Komatsu PC3000, PC4000, and Hitachi EX2500 need to operate for extended periods under extreme pressure.
In these harsh environments, the machine's "heart"—the hydraulic system—endures enormous thermal and mechanical stresses.
2. Downtime Costs
For Tier 1 mines, an hour of unplanned downtime for a single main excavator can result in losses of tens of thousands of dollars. Statistics show that over 45% of unexpected failures in heavy mining machinery are related to hydraulic system malfunctions, particularly those involving the main pump, control valves, and final drive.
