Product performance and features

ZYJ-320/180, 500/180, 800/180, 1000/180 column-type hydraulic rotary drilling rigs are based on the advantages and disadvantages of various domestic and foreign drilling rigs and rock drilling machines. Combined with the specific conditions such as coal mine tunnels and caverns, and after repeated research and development tests, a new series of drilling rigs with a new structure of column-type external drilling boom track, full hydraulic cylinder propulsion, and hydraulic cycloid motor rotation cutting were designed and produced. After testing by the "National Safety Production Beijing Rock Drilling Tool Inspection and Inspection Center", it meets the requirements of MTT198 and MTT199 coal industry standards, and all products have obtained the mining product safety mark approval certificate. This drilling rig has good drilling and rock-breaking performance, good overload capacity, fast drilling speed, reasonable structure, excellent technology, strong adaptability, easy operation, good safety, easy to disassemble, convenient transportation, large torque and feed and pull-out capacity, wide adjustment range, and is suitable for large-diameter gas drainage and water exploration drilling in coal mines or large-diameter near-horizontal drilling in ground engineering and engineering drilling perpendicular to the ground surface. It can drill near-horizontal directional holes in the entire coal seam underground, with a hole depth of more than 250 meters, a maximum efficiency of 20 meters/hour, a drilling diameter of 150 mm, and a final hole diameter of 94 mm. It is an ideal machine tool and equipment for underground drilling operations in coal mines in my country. Our company is willing to win the trust of users with excellent product quality and good after-sales service.
