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 HydraCrowd 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 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 HF is cleaner and more efficient than diesel-powered machines, plus its regenerative braking technology feeds electrical energy back to the grid.

Main Structures

Planetary Propel
Dual-motor independent drive
Two planetary gearboxes, each driven by a vertically mounted motor, are located on either side of the revolving frame. Dual-output pinion shafts from each gearbox engage the swing rack.
Crawler Dimensions - Overall Width 317.5 cm (125 in) Treads
A planetary gearbox with dual-output pinions provides the hoist torque transfer from the electric motor to the hoist drum gear.
Ground Bearing Pressure - Note
Ground bearing pressure is dependent upon many factors
Upper Works Overall Width - Including Standard Walkways
Ground Bearing Pressure - Total Effective Bearing Area (317.5 cm/125 in) Treads
57 m2 (248 kPa); 614 ft2 (36 psi)
