ZQ drill pipe power tong is an ideal well head tool for oil drilling, widely applied for making-up and breaking-out in offshore and onshore drilling operations and workover operations. Open-throat design of the ZQ series allows the tongs to escape from drilling pipe freely with high mobility. The tong is a combination of spinning tong and torque tong. It substitutes cathead, manual tong and rotary rope in making-up and breaking-out. The tongs are designed and manufactured according to API Spec 7K ¡°Specification for Drilling Equipment¡±
