Mechanical Drive Drawworks op Drilling Rig
• Drawworks positive gears allegear oannimme roller chain oerdracht en negative oannimme gear oerdracht.
• Driving chains mei hege krektens en hege krêft wurde twongen smard.
• De trommel lichem is grooved. De lege-snelheid en hege-snelheid einen fan trommel binne foarsjoen fan ventilating lucht buis clutch.
De wichtichste rem oannimt riem rem of hydraulyske schijfrem, wylst de helprem oannimt konfigurearre elektromagnetyske wervelstromrem (wetter of lucht koele).
