Details of DTH drilling rig:
* Fully hydraulic control is convenient and flexible: can adjust the drilling speed, torque, and promote axial pressure, anti-axial pressure, propel and improve the speed to meet the different conditions use of drilling tools and different construction needs.
* Top drive rotary drilling: easy to install and remove the drill rod, shorten the auxiliary time, and fasten the drilling of follow-pipe.
* 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.
* High working efficiency: thanks to full hydraulic and top drive rotary drilling, this drilling rig is adapt to a variety of drilling technology and drilling tools, has convenient and flexible control, fast drilling speed, short auxiliary time, and thus high operating efficiency.
* Low cost: drilling on the rock is dominated by DTH drilling technology, DTH hammer rock drilling operation is high efficiency, drilling cost of per meter is lower.
* High leg crawler type: high leg is easy for loading and unloading, no need of crane in truck loading. Crawler walking is more adapt to the movement in muddy field.
* The role of the oil mist: drilling on the rock is dominated by DTH drilling technology, DTH hammer rock drilling operation is high efficiency, lubricated impactor has longer service life, drilling cost of per meter is lower.
* Drilling rig chassis: It can be crawler chassis, and also be truck-mounted chassis.
