• DSGD-250 AC Gear Driven Drawworks

    National Oilwell Varco's  Dual Speed Gear Driven (DSGD) Drawworks are setting new standards in the drilling industry.

    Description

    NOV’s Dual Speed Gear Driven (DSGD) Drawworks are setting new standards in the drilling industry. These AC drawworks feature a two-speed helical gearbox mounted directly on the drum shaft which is ideal for any application where size and weight are critical factors. The two-speed functionality provides both extremely fast hoisting speeds and heavy hook load hoisting capabilities. The simple design of the DSGD Drawworks allows for easy operation and maintenance. Both transverse and longitudinal skid configurations are available to fit and substructure design.
