Reducing Environmental Impact
Using power efficiently, producing zero direct carbon emissions and regenerating power back to the grid
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 HF with Rope Crowd features AC IGBT electrics for greater uptime, lower operating costs and faster cycle times. Its high-flotation undercarriage designed for the oil sands ensures low ground-pressure for improved digging and loading in poor underfoot conditions. The state-of-the-art operator’s cab is the most comfortable and productivity-enhancing in the industry. The 7495 HF with Rope Crowd is available with a number of new technologies that provide operator assist and machine self-protection, enable proactive maintenance, and deliver real-time information on productivity and performance. An entirely electric machine, the 7495 is cleaner and more efficient than diesel-powered machines, plus its regenerative braking technology feeds electrical energy back to the grid.
