ZQ series of drilling pipe power tongs are a kind of perfect wellhead tools that can be extensively used in the fields of drilling or workover offshore and inland and upper unloading the pipe column screw thread during the workover job. The tongs have the roles of enhancing the working efficiency, safety and labor-saving. These series of tongs are open-mouth type, can freely escape the pipe columns with very good maneuverability. The torque tongs and cupboard button tongs are assembled as a whole, where upper unloading buttons replace the catheads, hanging tongs and spinning ropes. The power tongs conform to the SY/T5074 standards and API Spec 7K specifications.
