Through regular monitoring of machine conditions, mines can adopt a more proactive approach to maintenance and repair. Equipment health data is a key contributor to that approach. Data helps mines identify equipment problems long before failure.

Accessing the right data at the right time is critical to improving operational intelligence and machine predictive analysis. Cat® MineStar™ Health helps you meet that need by connecting you to your machines and delivering that important information. The MineStar Health portfolio set consists of Connectivity Enablers that collect, convert and transmit equipment data; and Applications that visualize, analyze and report health equipment data.
