Commodity name: ZDY-1250 full hydraulic tunnel drilling rig

1.Brief introductions of ZDY-1250 full hydraulic tunnel drilling rig

ZDY-1250 hydraulic tunnel drilling rig is used for coal mine: Z stands for drilling rig; D stands for tunnel; Y stands for hydraulic driven, and 1250 is the maximum output torque of 1250n. m.

2.Applications of ZDY-1250 full hydraulic tunnel drilling rig

ZDY1250 tunnel drilling rig is mainly used for drilling holes of gas pumping (row), grouting hole, water injection hole, anti process and pressure relief hole, geological exploration hole and other engineering drilling holes. Drilling rig can drill holes in the range of azimuth and dip angle specified in the basic parameter table.
