CML120Y(D) DTH Rotary Drill Rigs ( diesel engine driven, electrically driven)
CML120Y DTH Drilling Rigs are powered by an internal combustion engine and the impactor is powered by air compressor.
CML120D DTH Drilling Rigs are powered by electric motor and the impactor is powered by air compressor.
This two drilling equipments are multi-functional, self and flexible. Compared with conventional rigs, the biggest advantage is that the comprehensive energy-saving ratio is 45 % -50 %, another advantage is that it is suitable for both small and medium-sized mines operating and cross-operation. The whole operation is more stable and safe, more convenient to drill horizontal holes and lift blast holes.

Technical characteristic:
1 ) The internal combustion engines are of Yuchai engine or CUMMINS engine, both of which are stable to performance, easy to maintenance .2 ) chassis , tilt mechanism is selected from the reliable Ingersoll Rand CM351 system , structure .3 ) The walking motor is from Jie Shite, which can reach to 6T traction.4 ) The main pump is of high-pressure triple pumps, which are more powerful .5 ) The lifting motor is of axial piston motors , the lifting force is up to 20000N .6 ) The rotary motor is of gear pump (the rotational frequency and torque are adjustable according to the hardness of the rock )
Compared to other DTH drilling rigs in the market, the other advantages of CML120Y(D) drillings rigs are: most wearing/maintenance pasts are universal; there are three rotation speeds for option of drilling soft , medium and hard rock; the fuel savings are of 45% -50 % ; the operation is smooth so that it is very convenient for drilling uplift blasting; the reasonable structure makes the operating safer; The life of the rotational and other key components are long; it is equipped with two-way angle indications which is convenient for drilling pre-splitting; it comes with water removal to highly meet the mining environmental requirements .
