OWI's AC Drawworks will unitize with virtually any control system and driller’s cabin. This allows customer flexibility with different control and software vendors and respective support options. Our Drawworks is equipped with a direct drive gearbox that includes an electric motor driven, positive flow, external lubrication system. Spring set air released braking system for parking and emergency braking. Electric motor driven positive flow external lubrication system. The main braking action of the drum assembly is controlled by the Drawworks AC drive motor and AC drive system.
Input power for our AC Drawworks is provided by one continuous Drawworks duty AC drive motor coupled to a gearbox. The gearbox provides a direct drive link between the AC drive motor and the drum assembly through a series of gear driven internal shafts. By design all shafts are engaged gear to gear at all times to provide one constant drive ratio. There are no gear change selections or neutral positions available for the gearbox. The drum assembly is joined to the gearbox output shaft using a keyless locking device that locks the drum shaft into the hollow shaft of the gearbox. The gearbox supports one end of the drum assembly while a pedestal mounted bearing supports the opposite end of the drum assembly.
