MGY-120H Full Hydraulic Passage Construction Drilling Machine
The MGY-120H full hydraulic passage construction drilling machine is primarily used for construction in water conservancy, hydropower station passages, including anchor holes, drainage holes, grouting holes, advance holes, and core sampling holes for detection, as well as for the construction of support holes for tunnel pipe scaffolding. It features a feed stroke that can be selected according to the size of the hydropower passage, large drilling capacity, a wide speed range, convenient operation and adjustment of the hole position, and a novel structure.
