Overview

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.
