New Cat mining shovels feature upgrades to drive efficiencies, lower cost per tonadmin
Structural improvements boost longevity
Stress from every load passes through the swing rack. An enhanced design includes a single-piece rail casting that eliminates vertical segment cracks to increase durability. The rail provides a uniform path for roller movement, preventing rollers from coming loose and creating irregular wear patterns. The upgraded third rail improves access for inspection and retightening plus added support to the thrust rail during operation. New swing girder bushings and girder-to-chassis shim designs offer improved access, reducing service time.
All major rope shovel structures are built with high-strength steel and rugged castings, joined and thermally stress relieved to deliver reliable operation in harsh mining conditions. Full penetration, profiled and ground welds are made at critical junctures, and MT, UT and X-ray inspections ensure weld quality. Structures are stress-relieved to prevent cracking, and white painted interiors facilitate inspection.
Both the 7495 and 7495 HF ERS models now offer a full Cat bill of materials, streamlining the parts ordering process and improving parts availability.
Technology increases efficiency
Both the 7495 and 7495 HF come standard with Product Link Elite, which transmits critical machine operating data such as utilization, location and condition via cellular or site internet connection. Added router functionality helps to protect data security. Advanced productivity tools within Product Link Elite enable a cycle segmentation algorithm, and the combined data allows for advanced analysis of productivity.
When linked with the available Cat MineStar Fleet, real-time machine tracking produces a comprehensive overview of all equipment assets to assist with fleet management and productivity. Providing real-time feedback to improve loading efficiency, available MineStar Terrain uses guidance technology and an in-cab display to deliver precise dipper position guidance. Optional MineStar Health delivers critical event-based machine condition and operating data, while its advanced diagnostic and analytic tools improve service efficiency.
The standard Operator Assist – Enhanced Motion Control simplifies machine operation to promote high production while protecting the machine. This system is designed to yield more reliable crowd rope replacement schedules, full design life for hoist ropes, reduced wear on crowd brakes and longer life for hoist gear case components.
