The rotary table slows down a pair of bevel gear pairs during drilling operation to provide speed and torque output. Meet API 7K requirements and SY/T5531 standards. Features spiral bevel gear drive for higher loading capacity and smooth running.
A large winch mechanism that spools drilling line to raise or lower the drill stem. Features alloy steel shafts, pressure-lubricated high-strength chains, and a water-cooled brake system (band or disc brake) for long service life.
API Spec 7k standard products including F-500 to F-1600 series. Compact structure with reliable performance for high pump pressure and large displacement. Optimized for lower strokes to extend the life of fluid end consumables.
Designed for flexible connections between the riser and water faucet. Resists corrosion from hydrogen sulfide (H2S) and handles high-pressure water-based or oil-based mud. Reinforced with steel wire or steel link lines.
