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.

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.


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.

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.

Global Dragline Service & Support

Manufacturing the largest excavators in the world is a big job - supporting them is even bigger.

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.

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.

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.

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.

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

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.

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

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.

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.

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.

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.

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.
