Global Dragline Service & Support

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

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.

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.

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.

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.

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.

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.
