The NY-3A WLD-5T type hydraulic pipe twisting machine is mainly matched with the hydraulic vertical shaft drilling rig to replace manpower for unscrewing drill pipes and drilling tools, so as to mechanize and automate the process of unscrewing drill pipes, reduce the labor intensity of tripping operations, improve production efficiency, and improve labor intensity. The hydraulic pipe screwing machine is suitable for geological core drilling within 2500 meters deep, and the needs of drilling pipes in 42.50.60, 71, 73 and 89 in hydrological drilling.
