Introductions

KDJ-200 mechanical mast underground drill rig is mainly used for the drainage, support and anti-seepage treatment of various tunnels of hydropower stations, highways and railways. Besides, it can also be used for unstable rock and slope geologic hazard treatments. Its drilling method is mainly diamond drilling or polycrystalline diamond compact bit drilling, and DTH air hammer drilling can also be adopted.

Features

KDJ-200 drill rig adopts mast power unit structure and the rotation of power unit is mechanically driven.
The feeding and back dragging of power unit are directly achieved by adopting hydro-cylinder. Its feed stroke is long and the drilling is stable and reliable.
The mast angle is adjusted by hydro-cylinder. It has good dismountability and it's easy to maintain. KDJ-200 drill rig has 8 gears of rotation speed, which can meet the speed requirements of different drilling technologies.
