FREEDOM for Draglines
“This [dragline] is the best one we have. It’s easier to run. We have no problems. On the uptime log, this one is in the mid to high 90% range. When you want to run it fast, it’s a lot faster. All of the others are down a day every week or two for maintenance. The 770 is down one day a month. We just run. We are running about two months ahead of schedule. A lot of that has to do with not being down. This machine just digs!”

Control systems for draglines
Controls and automation
The FREEDOM for Draglines control system frees you to upgrade your draglines with higher-performance DC power systems, convert DC machines to AC, and integrate new third-party technologies, so you can achieve faster cycle times, increased availability, and lower energy consumption.
The FREEDOM control system utilizes off-the-shelf components and detailed diagnostics to speed up maintenance and minimize downtime. Plus, the highly customizable open-architecture system gives you total data transparency.
Machine and fleet monitoring
Tracking variable data trends for the rotating equipment that ultimately keep your draglines moving can help you optimize machine performance and reduce maintenance costs with right-timed service.
Our intelligent, inspection-based WISDOM system identifies emerging machine health issues long before faults occur, so you can schedule parts delivery and service to minimize the impact on production. Ensure the productivity of your draglines with WISDOM.
Power systems for draglines
Specifically designed to withstand harsh mining conditions and the ultra-heavy cyclical loading inherent in dragline operation, rugged FLANDERS AC and DC power systems improve lifetime dragline productivity.
Dragline drive systems
AC drives
The FLANDERS R&D team developed the first liquid-cooled AC drive for draglines. Liquid cooling reduces noise and heat levels in the house and makes it possible to place electronics in a sealed enclosure, eliminating the need for dust filters and corresponding maintenance.
Our AC dragline drive system is 92-93% efficient, compared to ~80% for DC systems, reducing your cost per ton by lowering electricity costs of running your dragline.
DC drives
We offer higher-performance, speed-range matched ABB drop-in replacements for DC dragline drives. We can also upgrade your current DC drive systems to your specifications.
Dragline motors
Hoist | Drag | Swing | Propel
We designed our own line of dragline motors after years doing dragline field service and failure forensics for our clients. The fundamental problem was this: many draglines were built using motors re-purposed from other industries, and they simply weren’t built to withstand dragline load cycles and run 24/7 x 365.
FLANDERS dragline motors are purpose-engineered and purpose-built for draglines. They have, among many technology improvements, complete Class H+ (220° C) insulation and have copper-barred rotors for higher efficiency and better torque density.
Manufactured in our state-of-the-art facilities, to tighter specs than conventional systems, FLANDERS drop-in dragline motors perform better, last longer, and require less maintenance—all of which lower your cost per ton.

Dragline motor-generator (MG) sets
Generators
In the event of single- or multiple-unit failures, FLANDERS can quickly deliver drop-in replacement generators. We offer a wide variety of DC replacements as well as premium rebuilds for Westinghouse and General Electric generators.
Additionally, we’re the only source for FLANDERS high-output generators, designed in-house, which can deliver an increase of up to 50% in rated power (kW). To realize the full potential of our high-output generators, you’ll also want to upgrade your draglines with FLANDERS high-output synchronous motors.
Turn greater generator power into greater dragline productivity, with FLANDERS synchronous motors.
Synchronous motors
Our FLANDERS high-output dragline motors complement the higher power rating of our high-output generators. We can upgrade or replace any Westinghouse or General Electric synchronous motor.
In fact, if you’re looking for improved motor technology or to modernize an obsolete machine, FLANDERS has the engineering knowledge and capabilities to replace ANY synchronous motor in your operation.
FLANDERS designed and manufactured the largest synchronous motor ever to be installed on a DC dragline.

Our DC to AC dragline retrofit is one of the most significant, practical mining tech advancements of the last decade. DC draglines were OEM standard from the ‘60s into the ‘90s. Now, a lot of those machines are slowing down and approaching retirement at a time when budgets are tight due to market pressures. Extending the life of those draglines by 15+ years, for a fraction of the cost of a new machine? That’s a big deal, especially when you consider the additional productivity, energy savings, and control you get from AC.
