The 9020XPC dragline, featuring a 85 to 122 m3 (110 to 160 yd.3) bucket capacity range, offers 100 to 130 m (325 to 425 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.
In addition, we have designed and manufactured the following for our dragline products:
- AC drives that are compact, modular, and maintenance friendly, allowing fast and easy replacement that reduces critical downtime
- P&H motors that are designed specifically for draglines, offering increased speed, improved thermal margin, and higher peak horsepower
Superior gradial tub
- Greater strength-to-weight ratio handles multi-dimensional loads, which allows increased reach and load capacity
- Gradial design provides multiple load paths for ground-induced forces, eliminating weak points and extending the life of the tub
- Patented Verti-Shield welding process joins all intersecting plates with one continuous weld, resulting in minimal distortion and residual stresses
Rugged roller circle and roller path
- Large-diameter roller circle provides low loading in the rail pad support structure and increases tub and deck structure reliability
- Specially processed forged steel is used to provide long roller and rail life
- Self-lubricating roller bushings
- Internal gear design of the swing rack provides better load sharing between the pinion and teeth
- Large-diameter rack reduces gear and pinion loads
Optimized boom
- Four-chord boom design provides additional stability
- Wide flange chords allow for full penetration weld joints, as well as ease of inspection from boom walkways
- A-frame optimized to reduce loading of superstructure components and maximize Rated Suspended Load (RSL)
- Patented design with a flatter underside improves visibility of the bucket when dumping at limits and balances axial boom working loads
- Saddle-mounted boom point sheaves allow 16.5° of swivel to follow the pendulum lag of the hoist rope
Superior swing design
- P&H planetary transmissions are designed for severe-duty mining applications
- More efficient power transmission means less frictional loss and backlash
- Four planet pinions reduce tooth loading at each gear mesh
Designed for easy maintenance
- Platforms allow easy access wherever routine maintenance is required
- Wide stairways provide efficient access to different levels
- Integral lifting hooks for easier moving/setting of cases and transmissions
- Excellent headroom under the deck allows unsurpassed access to top of tub for ease of inspection and maintenance of swing racks, rollers, and rails, as well as superior access to collector ring
- Oil and grease containment in roller circle is collected with felt paper for easy, environmentally responsible disposal
Constant Contact fairlead
The Constant Contact fairlead design features:
- Sheave arrangement that maintains constant rope contact
- Optimized lower swivel frame for high strength and low swing inertia
- Optimized sheaves for high strength, low inertia, and improved throat sheave geometry
- Superior ground height for dozer clearance
- Design that allows easy maintenance of sheaves, bearings, and bushings
Machinery house ventilation and dust removal
The filtration system features:
- Large filter modules
- Direct-drive centrifugal blowers for reduced maintenance
- Easy access to both sides of the filter for easy cleaning
Please note that these are typical specifications. However, all draglines are custom tailored to your application, so specifications for your machine may vary.
