1.Deep drilling capacity,HQ-1800m,NQ-2400m.
2.Multiple speed grades in fforward & reverse revolving ,meets different drilliing requirements.
3.Long spindle stroke,higher drilling efficiency.
4.Automobile Grade Clutch and Transmission Box,stable running lower noise adn higher transmission efficiency.
5.Frame sliding retraction,easy to connect and replace drilling tools.
6.Water brake system to the hoist winch,steady delivery to lower drilling tools.
