Electric Rope Shovel | 7495 with Rope Crowd

The Cat 7495 with Rope Crowd is an entirely electric rope shovel with AC IGBT electrics, regenerative braking and available operator-assist and machine self-protection technologies.

AC IGBT electrics

Features

AC IGBT electrics for greater uptime, lower operating costs and faster cycle times.
Operator’s cab described as the most comfortable and productivity-enhancing in the industry.
Available technologies provide operator assist, machine self-protection, proactive maintenance and real-time productivity and performance information.
Entirely electric operation is cleaner and more efficient than diesel-powered machines. Regenerative braking feeds electrical energy back to the grid.
Immense payload capability, low maintenance requirements and high reliability for low cost-per-ton loading in long-life mines.
