Compliance and Reliability
Product Features
• The drawworks incorporates forced lubrication for the chain drive and involute spline-type transmission clutches, reducing wear and extending service life under severe working conditions.
• The drilling contractors can configure the main brake system with either a band brake or a disc brake, depending on rig requirements. For enhanced safety in extended tripping or heavy-load lowering operations, auxiliary braking options include eddy current brakes or Eaton water-cooled dynamic brakes, providing smooth and controlled deceleration.
• These systems ensure reliable stopping power, reduced heat build-up, and safe operation even under extreme loads.
• With its combination of strong structural components, advanced braking systems, and high efficiency, the MTPM drawworks stands as a proven solution for drilling contractors seeking durability, adaptability, and operational safety.
Our drawworks with alloy steel shafts, water-cooled braking, forced lubrication, and multiple brake options, designed for safe and efficient drilling rig hoisting operations.
