Tried and True AC IGBT Electric Drive System

You will experience greater machine uptime, lower operating costs, and faster cycle times via our AC electric rope shovel designs that leverage institutional knowledge built on 30 years of experience commissioning more than 200 AC equipped machines worldwide.

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 eliminating 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

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.

Faster Cycle-times, Improved Line-of-sight, and Safer Maintenance

Enhance both loading safety and productivity at your mine with a lighter front-end that affords better line-of-sight and serviceability.

• Faster swing times resulting from reduced swing inertia of lighter front-end

• Improved left-hand line-of-sight with deck-mounted crowd machinery that reduces visibility-impeding components on the boom

• Reducing fall hazards, deck-mounted crowd machinery allows the majority of crowd maintenance to be completed from the protection of the machinery house deck

Reduced Cracking and Extended Component Life

Experience greater uptime and component reliability with our unique, yet robust front-end design

• Highly crack resistant one-piece, forged dipper handle

• Extending boom and dipper handle life, rotating handle design transmits torsional stress into the hoist ropes

• Reducing wear and cracking at the boom/dipper handle junction, crowd and retract ropes or hydraulic fluid absorb kickback force caused by dipper colliding with poorly shot material

• Replacing racks and pinions with tubular handle and ropes or hydraulic cylinder greatly reduces lube usage

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

Simplified Maintenance

Get your primary loading tool back to work quickly with simpler, more straight-forward maintenance.

• Design facilitates handle installation and requires fewer adjustments

• Crowd and retract rope adjustments are made from the safety of the machinery house roof – rather than on the boom, as required by rack and pinion systems

• Elimination of bi-annual, major maintenance handle re-racking procedure with tubular handle instead of racks

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

Greater Uptime

• Improves reliability by eliminating the electric rope shovels' leading downtime occurrence: maintenance on the latch assembly

More Productive Digging/Loading

• Increases efficiency by reducing lost loads

Better Component Life

• Reduces component wear by relocating components away from the harsh conditions of the lower dipper door

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

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.

Third Rail Swing System

See more

Providing optimum speed and cycle time, all while extending component life, our swing system is designed to help keep your rope shovel swinging longer and filling trucks faster.

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

Sustainability

See more

Meeting the needs of today without compromising the needs of tomorrow is the goal for all Cat machinery. The commitment to helping you operate safely and sustainably is affirmed in the production of the 7495 HF rope shovel.

Cat Rope Shovel Sustainability – Electric Power

More efficient than diesel powered machines, Cat electric rope shovels are entirely electric and therefore experience less heat loss.

Cat Rope Shovel Sustainability – Regenerative Power

Cat electric rope shovels use regenerative braking technology to convert kinetic energy from shovel motions into electrical energy when braking. The electrical energy that is generated is then fed back to the grid. Without regenerative braking, the kinetic energy would be burned off as heat.

Cat Rope Shovel Sustainability – Long Life Cycles

Fewer component change-outs result in less waste. Component change-out intervals for electric rope shovels are generally longer than those for similar-sized hydraulic machines.

Cat Rope Shovel Sustainability – Rebuilds

Saving you money and reducing waste in the environment, electric rope shovel motors and gearcases can be rebuilt.

Overview

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.
