Joy Global has developed a true center of excellence with our dragline service organization. Our staff comprises more than 800 years of combined experience in draglines, meaning we are the OEM with more institutional dragline mining knowledge than anyone else in the industry.

The experience is most evident in our dragline upgrade programs. Only Joy Global provides a comprehensive line of P&H upgrade components for P&H draglines, as well as for draglines from every other major manufacturer. When we exchange your current high-maintenance OEM components with reliable, proven P&H components, you will see increased machine reliability and availability, which in turn translates to higher production.

We have planetary swing transmission, dragline boom designs, ventilation modules, and other upgrades available to make your dragline more dependable and productive. All our upgrade components are designed for severe dragline operations and have a proven track record in numerous mining applications around the world.

  • Suspension pendants
  • Propel and swing stability
