7495 Electric Rope Shovel
DESCRIPTION
Electric 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.A 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 eliminates the need for high frequency bonding
Comfort Infused, State-of-the-art Operator's Cab and Station
Providing more comfort, added safety, and greater reliability, our newly designed state-of-the-art operator's cab will help you produce more. The product of a multi-year collaboration with mining companies and rope shovel operators from across the globe, our Design Engineers, armed with insights into the aspects most desired by you, have designed what we believe to be the most comfortable and productivity-enhancing operator's cab in the industry.
Improved Performance

- Reduced cognitive fatigue and enhanced productivity via the intuitive and visually aesthetic display screens
- Display screens adjust for brightness and contrast to meet operator preference
- Climate control system automatically maintains a preset temperature
Enhanced Safety
Ensure the safety of your operators with industry-leading cab safety features.
- For safer double-side loading and reduced crawler link damage, the large windshield, side windows, and floor window provide superior far-side and vertical line of sight for industry-leading visibility
- Augmented line of sight and improved operator situational awareness via external camera system with direct feed to five overhead monitors in cab
- Dual door design facilitates easy entry and exit from the cab and provides for rapid escape in case of highwall collapse or other emergencies
- Reduced trip hazards with no-step floor
- Enhanced safety during operator training with additional emergency stop button within reach of trainer seat
Better Training
Reap learning and performance benefits from the enhanced training environment of our first-in-industry three-seat cab design.

- Adjacently positioned trainer seat provides optimal view of working face, facilitates communication during training, and provides ready access to the trainer emergency stop button
- Elevated observer's work station, positioned behind the operator seat, provides space for laptop and optimum visibility of operator station and digging environment
More Reliability
To ensure consistent and reliable performance in the harshest mining conditions, cab components were carefully selected for ruggedness.
- Custom cabinets designed to eliminate rattling
- Heavy-duty refrigerator built to withstand shovel vibrations
- High efficiency, adjustable LED lights optimize visibility
Safety, Reliability and Productivity Advantages Afforded by Our Unique Design
Greatly improved digging efficiency, safety, and component life are the results of our unique, yet robust front-end design, particularly when compared to rack-and-pinion systems.
Easier, More Efficient Digging
Realize more productive and efficient digging facilitated by our wide-set boom point sheaves.
- Twin hoist ropes balance dipper pull in the bank via wide-set boom point sheaves, automatically distributing digging force where it is needed most
Results Are What You'll Get from the HydraCrowd System
The HydraCrowd system provides outstanding performance and high reliability. This innovative system goes a step further than the Rope Crowd system, making maintenance more predictable and keeping your rope shovel in production longer.
Eliminates Routine Crowd/Retract Rope Replacements
HydraCrowd extends maintenance intervals and improves your overall productivity with a patented innovative design that replaces crowd and retract ropes with a hydraulic cylinder.
- Increases uptime and enhances productivity via reduced scheduled maintenance hours
- Eliminates routine crowd/retract rope changes
- Extends major maintenance interval to two years
- Maintains the benefits of our unique front-end design
Description of LatchFree Dipper System
- A strong steel holding link and eccentric replace the traditional dipper latch assembly
- Components are mounted to dipper back, rather than dipper door, away from the material flow
- The door closes by gravity as the dipper is lowered
- Comes complete with a comprehensive training program
FastFil Dipper – Faster, Fuller Dipper Loads
Improving fill factors and helping you hit your productivity targets the trapezoidal shape of our FastFil Dipper accommodates the natural configuration of the load, eliminating voids that occur with box-shaped dippers.
- Trapezoidal shape eliminates the void that occurs at the back of the dipper with the traditional dipper shapes
- Improved maneuverability and faster swing times resulting from reduced dipper size and weight
- Improved bank penetration and elimination of bulldozing for material turbulence due to optimized lip and rake angles
- Reduced load and dump times facilitated by shorter dipper body
- Fill factors average > 100% (110% typical)
- Available in sizes up to 48.9 m3 (64yd3)
Achieve Targeted Loading/Hauling Production with Perfectly Paired Cat Rope Shovels and Mining Trucks
For full truck payloads with minimum loading time, an efficient loading/hauling system begins with an optimized equipment match. Cat electric rope shovels are matched with Cat mining trucks to maximize volume of material moved at the lowest operating cost per ton.
Even Loading
Achieve maximum component life with our swing system design that ensures reduced and even swing rack wear.
- Eliminating the need to rotate the swing rack, two swing gearcases, positioned 180° apart, produce even swing rack wear
- Reducing wear on the swing rack and swing pinions, straddle-mounted, dual-output pinions decrease tooth loading
Better Serviceability
Mean-time to repair is reduced, as most repairs involve the third rail, rather than the rollers.
- The easy-to-replace third rail, rather than roller flanges or the swing rack, serves as the primary wearing part in the system, greatly simplifying maintenance
- Provides roller access without jacking up the upper half of the machine
