KG940A surface DTH drilling rig is based on KY140A surface DTH drilling rig with innovatively designed traveling part, guide, drill boom, and complete machine arrangement. It mainly has the following characteristics:

1, It is equipped with domestically well-known Yuchai YC4D80(Emission 2) diesel engine with strong power and reliable performance.

2, It using the better trolley travelling mechanism and the circular boom, novel structure, convenient adjustment, expands the range of drilling,It can drill the hole low level.

3,Low gravity center,high ground clearance,It can travel on the rough terrains.Special wheel motor drive, strong climbing ability, low failure rate,Advanced automatic balancing and braking system make the dill can travel stability,driving safety.Prevent to take off the chain set is improve the properties of dirll.It can travel without compessor.

4,Powerful feeding and rotating system,New slewing mechanism is composed of cycloid hydraulic motor and the planetary gear reducer, provides a powerful torque, reduce the rate of drill,High power hydraulic motor drive feed mechanism can produce 20 kn lifting force, to adjustregulating valve for the best propulsion

5, It is equipped with plastic plate to reduce wear of the guide rail.
