7295 Electric Rope Shovel
Product description
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. Our smallest rope shovel, the Cat 7295 has a payload of 45 tonnes (50 tons) — about half the payload of our flagship 7495. But like its larger counterpart, the 7295 features AC IGBT electrics for greater uptime, lower operating costs and faster cycle times. The 7295 is cleaner and more efficient than diesel-powered machines, plus its regenerative braking technology feeds electrical energy back to the grid.
