KG920B mining crawler drilling rig is an improved type of DY125, Optimized and updated hydraulic system, Drill Rigboom parts, walking parts and so on,Drilling Rigadopt high power diesel (YC4D80), Drilling Rigs made the stronger climb ability, reasonable drill angle, faster rotary and feed speed, water well drilling rigs have longer service life of motor and more reliable.
Borehole Brilling Rig Powerful feeding and rotating system
The borehole drilling machine feeding structure by large power hydraulic motor can supply strong torque reserve and reduce the sticking rate.
The Rock Drilling Machine feeding structure can supply a lifting power of 20N by large power hydraulic motor. Adjust the crawler drilling rig control vavle on the operating valve can obtain the needed optimum propelling effort.
