1. Top drive rotary drilling: easy to install and remove the drill rod, shorten the auxiliary time, and fasten the drilling of follow-pipe.
2. Multi-function drilling: A variety of drilling processes can be used on this rig, such as: DTH drilling, mud drilling, roller cone drilling, drilling with the follow-pipe and the being developed core drilling, etc. This drilling machine can be installed, according to user needs, mud pump, generator, welding machine, cutting machine. Meanwhile, it also comes standard with a variety of winch.
3. Crawler walking: Multi-axle steering control, multiple steering modes, flexible steering, small turning radius, strong passing ability
4. Operating system: the internal intensive operating platform is designed in consideration of ergonomic principles, and the operation is comfortable.
18. Power head: full hydraulic top driving force head, the output end is equipped with a floating device, which effectively reduces the wear of the drill pipe thread.
