The Top Drive System (TDS) is one of the greatest technological revolutions in petroleum equipment, designed to replace the traditional Kelly and rotary table. TDS enables drilling with triples instead of singles, reducing the volume of work for makeup and breakout by two-thirds and significantly increasing drilling speed.

The rotary table is a critical component of the drilling rig. It utilizes spiral bevel gear drives for higher loading capacity, smooth operation, and long service life. The casing features a casting and welding structure for superior rigidity and precision.
Essential hoisting mechanism for the rig, acting as a large winch that spools drilling lines to raise or lower the drill stem and bit. Features include alloy steel shafts, pressure-lubricated high-strength chains, and water-cooled brake rims.
Compliant with API Spec 7k standards, these pumps are sturdy, compact, and reliable. They feature longer strokes to operate at lower speeds, improving water supply performance and extending the service life of fluid-end consumables.
