Drawworks Drive Mekanik ing Rig Pengeboran
• Drawworks Gir positif kabeh nganggo transmisi chain roller lan sing negatif nganggo transmisi pindah.
• Nyopir chain karo akurasi dhuwur lan kekuatan dhuwur dipeksa lubricated.
• Awak drum wis grooved. Ujung drum kanthi kacepetan lan kacepetan dhuwur dilengkapi kopling tabung udara ventilasi.
Rem utama nganggo rem sabuk utawa rem cakram hidrolik, dene rem tambahan nganggo rem arus eddy elektromagnetik sing dikonfigurasi (banyu utawa hawa adhem).
