7495 with Rope Crowd
Brand: Caterpillar CorporateElectric rope shovels have been successfully removing overburden and ore on mine sites around the world for more than a century.
Driven by a vision to make these highly productive machines safer, more reliable and even more productive, we challenged the status quo and built an electric rope shovel that's better.
FeaturesA SIMPLER SYSTEM
A streamlined AC system design that runs smoother, has fewer parts, and is easier to maintain, are the benefits you will realize, and the result of three decades of continuous improvement.
- A single, centralized control rack reduces parts requirements, eliminates communication issues between racks, and simplifies maintenance
- A single, compact drive cabinet houses the controller and drives to simplify assembly, troubleshooting, and maintenance
- Fuses, circuit breakers, and line filters have been eliminated reducing potential points of failure and overall parts requirements
- Parallel inverters have been removed to prevent uneven loading and to reduce the number of inverters required by the system
- The IGBT modules have been designed to be interchangeable between inverters and Active Front Ends (AFEs) and between motions and machines
A SAFER SYSTEM
Your safety remains our highest priority, and is evident in our AC system design.
- The high voltage DC bus is located in the back of the drive cabinet and is never exposed during maintenance or troubleshooting
- The centralized control rack keeps maintenance personnel away from high voltage components when troubleshooting the controller
- Shielding blocks induced currents eliminate the need for high frequency bonding
A ROBUST SYSTEM
Helping to ensure your rope shovel remains in service, our AC system is designed to perform in the toughest mining conditions.
- The robust, welded drive cabinet was designed to withstand severe and consistent vibration
- An isolated, positive-pressure room houses the drive/controller cabinet to protect it from dust and debris
- Mine-grade components are used to ensure system performance and long, trouble-free life
