The direct drive top drive is a new type of drilling equipment integrating mechanical and electro-hydraulic. It is equipped with a special high-torque AC variable frequency motor independently developed by our company and a high-performance variable frequency control system with core algorithms with independent intellectual property rights; it has fewer failure points and reliability High, strong overload capacity, wide adaptability and other characteristics.

(1) Cancel the gearbox and auxiliary system, the structure is simple and easy to maintain;

(2) Reduce mechanical failures, greatly improve reliability and use efficiency;

(3) The ground-speed and large-torque motor directly drives the drill string, which has a compact structure and solves the shortcomings of insufficient space for the old drilling rigs.
