Benefits & Features

More than 1,100 of these draglines have been produced and delivered to every major continent over the past century­ – more than any other mining dragline manufacturer. Today, Caterpillar continues to lead the way in the evolution of these excavators and maintains the expertise to keep them operating reliably. A Century of Leadership From the largest dragline ever built to the world’s first AC and direct-drive draglines, Bucyrus led the industry with ground-breaking dragline innovations. » Learn More We will accomplish this goal through coordinated efforts and accountability at all levels of our organization. Cat draglines improve the safety of mine operations in many ways, such as reducing the amount of personnel necessary to move massive amounts of material and providing a safe, environmentally-controlled operator cabin. Safety Our goal is to provide a safe workplace while producing products that exceed the needs of our customers and shareholders. As a responsible corporate citizen, we commit to our goal of Zero Harm as related to the safe manufacture, installation and operation of our products. » Learn More At Caterpillar, the connection between machine uptime and customer profitability is well understood. In order to ensure that a customer’s dragline investment provides the highest level of performance, productivity and financial return, we offer a stable of top-quality, globally-available service and support resources. Global Dragline Service & Support Manufacturing the largest excavators in the world is a big job – supporting them is even bigger. » Learn More Our application engineers work collaboratively with existing and potential dragline customers, considering factors such as digging environment, mine life, mine plan and annual production targets, among others, to determine the proper dragline configuration for each customer’s mine site. Application Engineering To ensure that a customer’s dragline investment will garner expected returns, Caterpillar employs application engineers who specialize in analyzing mine environments and applying the findings to recommendations for new draglines specifically designed to meet the customer’s productivity targets, as well as upgrade recommendations for existing dragline fleets. » Learn More Cat mechanical upgrade solutions include, but are not limited to: Major dragline structure repair/replacement for improved reliability and productivity enhancement Boom modifications to optimize Rated Suspended Load (RSL), operating radius, digging depth and dumping height Re-engineered components for improved performance Mechanical Upgrades Caterpillar provides full mechanical component upgrades for existing draglines. In-house and third-party Finite Element Analysis expertise is employed to ensure that replacement parts outperform the original components. » Learn More Cat electric upgrade solutions include, but are not  limited to: Drive System upgrades for enhanced performance (AC & DC) Programmable Logic Controller (PLC) & Human Machine Interface (HMI) upgrades for enhanced  safety and availability Production Monitoring System for optimized productivity Onboard troubleshooting & remote diagnostics for improved reliability Electrical Upgrades Caterpillar develops and implements dragline electrical upgrade solutions that allow the electrical system to work in harmony with onboard mechanical systems. Whether AC or DC electrical service is required, specialized and locally-based Caterpillar personnel can provide tailored solutions that address the customer’s specific needs. By implementing electrical upgrade solutions, owners of legacy draglines can reap the benefits of the latest technology, reducing operating cost and improving machine productivity and reliability. » Learn More The ability to offer a turn-key solution of OEM dragline parts, dragline service expertise and local resources positions Caterpillar as an industry-leading provider of dragline relocation and field assembly solutions. Likewise, the unmatched institutional knowledge of current and legacy dragline models enables informed upgrade recommendations, leading to more productive and reliable operations following relocation. Dragline Relocation & Field Assembly Performing top-notch overhaul and relocation services are fundamental elements of the Cat dragline portfolio. Caterpillar understands that, despite the dragline’s unmatched ability to remove overburden at extremely low cost per ton, the initial capital outlay and time it takes to produce a new dragline can lead mine owners to explore other alternatives, including the purchase and relocation of pre-owned draglines. » Learn More Caterpillar product trainers have years of experience with hands-on and classroom training, offering the necessary skills to implement changes on all aspects of operation, machine management and maintenance. In addition, Caterpillar utilizes cutting-edge technologies to improve knowledge retention, increase training efficiency and create a safer learning environment via machine simulation. Around the world, Caterpillar provides total training solutions and support. Customized Training Caterpillar provides customized on-site and/or classroom training for dragline operators and mine operation supervisors with the goal of developing internal training competency for the customer. The comprehensive training package is designed in module form to target key production issues specific to a given customer’s operation. » Learn More Standard Configuration Bucket capabilities: 24 to 34 m3 (31 to 45 yd3) Boom length options: 75 to 101 m (246 to 330 ft) Rated Suspended Load (RSL) capabilities: 71 000 to 102 100 kg (156,500 to 225,000 lb) Approximate working weight range: 1 770 000 to 1 988 000 kg (3,902,000 to 4,382,000 lb) Provides environmentally friendly means of overburden removal: consumes less power, produces less heat and noise, and emits fewer greenhouse gases than other methods of overburden removal Multiple Specifications Available Cat® Draglines are a primary excavating tool in many surface mining operations worldwide. They’re highly productive and offer the lowest material cost per tonne in the industry. » Learn More
