7495 HF with Rope Crowd
7495 HF 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 eliminate 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.

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
Description of Cat Front-end
- Stress-relieved, impact resistant steel boom with twin box girder design – 100% penetration and UT quality welds on all major splice joints
- Maintenance-free, one-piece, high-alloy, forged steel handle designed to rotate freely in the saddle block
- Saddle block, with one-piece liner, rotates about shipper shaft on a manganese bronze bushing, guiding the longitudinal movement of the handle
Results Are What You'll Get from the Rope Crowd System
The Rope Crowd system provides outstanding performance and high reliability. This traditional system is a tried-and-true design, proven reliable in mine sites across the globe for three-quarters of a century.
Consistent Performance, Trusted Reliability
Our traditional rope crowd provides predictable and reliable performance established over 75 years.
- Rack and pinion misalignment challenges are eliminated with our tubular handle design
- Front-end cracking is reduced, as crowd and retract ropes absorb shock
- Torsional stress is eliminated, when using proper digging techniques, with our rotating dipper handle, reducing cracking and extending component life
Avoid the Leading Cause of Rope Shovel Downtime for Over a Century
Spend more time digging, and less time performing unplanned dipper maintenance with the LatchFree Dipper System. The first successful solution to the number-one cause of rope shovel downtime, the LatchFree Dipper System replaces the maintenance-intensive latch assembly with a strong steel link mounted to the dipper back, away from material flow. To ensure you achieve maximum benefits, the system 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 48.9m3 (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
