The Drilling Rig Model YGSL-120R, which is a full hydraulic top drive double power head crawler drilling rig, can be applied for different kinds of drilling technique methods and a variety of ground conditions. Especially in the difficult work condition, such as the incompact ground area, the gravel place, and the fragment rock stratum, this drilling can always provide the operator excellent solutions.YGSL-120R Drilling Rig has already been widely used in boring not only the GSHPs hole and water well or water exploration hole; but also the drain hole and large tonnage prestressed anchoring hole of the geotechnical engineering, such as boreholes on side slopes of dams, railways, highways, etc.; pipe sheds drilling of the underground engineering; the grouting reinforcing hole drilling; the small foundation pile boreholes; and the drilling holes of landslide preventing and the treatment engineering of rock collapse. Features ● Drilling Rig is installed the front and the rear power heads, which makes a variety of drilling methods possible. For example: single rotating drilling for inner or outer drilling tools itself; inner drilling tools rotating drilling, but the outer casing pipes reversing drilling; etc. ● There are two levels (high speed or low speed) of rotary speed output. The rotary speed can be stepless adjusted in rating speed range of each level in order to be suitable for a variety of boring methods and techniques, such as rotary drilling, impact boring (Down-the-hole Hammer drilling), impact and rotary drilling, auger drilling and so on.
