1.    This drill has more positive speed grades and reasonable speed range, with bigger output torque at low speed which gives it an extensive use range; it is Suitable for alloy, diamond mud drilling and DTH hammer drilling as well.

2.    It has 2 reverse inversion speed in order to deal with accident.

3.    JDL-300 works with mechanical transmission and auxiliary hydraulic transmission which effectively reduce the power consumption, and also makes drilling cost lower.

4.    JDL-300 uses long stroke multiple speed system, mechanical power head with stroke as 3400MM,to improve drilling efficiency, prevents accidents such as balling up and burning bits from happening.

5.    JDL-300 adopts double oil pump, single pump works whilst drilling, double pump works whilst hoisting, which lower power loss and shorten auxiliary time.

6.    It has highly advanced mechanical structure and reasonable layout which is convenient to repair and maintain.

7.    Using the crawler chassis with support oil cylinder which has a stroke of 1.5m, it can be loaded automatically and moved easily.

8.    Some interfaces are reserved to expand functions according to the technological requirements of different customers.
