- 55 to 93 m3 (75 to 117 yd.3) bucket capacity range
- 90 to 125 m (300 to 405 ft.) boom length range
- Gradial-design tub for multiple load paths to eliminate weak points and extend tub life
- Integrated Centurion electrical control system for supporting maintenance and performance-optimizing systems
- Largest diameter roller circle in class, with more rollers for better load distribution, and large-diameter rack for reduced gear and pinion loads
- Optimized A-frame for reduced load forces and maximum-rated suspended load
The 9020C dragline, featuring a 55 to 93 m3 (75 to 117 yd.3) bucket capacity range, offers 90 to 125 m (300 to 405 ft.) boom length range, allowing you to customize the boom length for your specific mine geometry. The Centurion electrical control system is standard on this large-capacity dragline.
Please note that these are typical specifications. However, all draglines are custom tailored to your application, so specifications for your machine may vary.

Centurion electrical control system
The Centurion electrical control system utilizes standard industry protocols, while still providing a platform that is scalable for future advancements.
- Intelligent sensors and I/O devices monitor and control the dragline, enabling machine health and reporting, as well as performance enhancement systems
- Advanced communication and monitoring links to both your mine management and your maintenance crew reduce downtime
- Centurion-based graphic user interface in the operator cab and machinery house provide continuous feedback on all operating systems, empowering your operators to pursue peak performance from the dragline
- Uses finger-safe 24VDC for maximized operator safety
- Distributed I/O drops and fiber-optic cable linking drives work with a supervisory controller to reduce wiring, resulting in fewer potential points of failure and simplified troubleshooting
