Overview

THE ULTIMATE IN EFFICIENCY AND RELIABILITY

Cat® Electric Rope Shovels combine immense payload capability with low maintenance requirements and high reliability to deliver the lowest cost-per-ton loading solution for long-life mines. The Cat 7495 HD is a smaller, tougher version of the 7495. Like the 7495, it features AC IGBT electrics for greater uptime, lower operating costs and faster cycle times. The 7495 HD is cleaner and more efficient than diesel-powered machines, plus its regenerative braking technology feeds electrical energy back to the grid.

Benefits

Reducing Environmental Impact

Using power efficiently, producing zero direct carbon emissions and regenerating power back to the grid

Efficient Loading

With fast swing times, improved line-of-sight, wide-set boom point sheaves and LatchFree Dipper design

Leader in Reliability and Uptime

With proven AC IGBT Electric Drive System that is streamlined, simple and easy to maintain

  • Cat Health

    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.
