By certification 
ROC-22 Type RC drilling rig is mounted on a crawler chassis, driven by full hydraulic system, equipped with our own developed proprietary power head, which is used to drill vertical or inclined hole, and also being used with the drilling techniques way of the following:
* Auger drill method
* DTH Hammer method
* Circulation drill with mud
* ODEX methods
* Multimedia RC method
The RC drilling rig is able to resolve the difficulty of boring in the soft and loose cover ground condition, the screes and gravels area and also the fragmentation stratum according to different drilling techniques ways. Therefore, it is widely used in varieties of the RC drilling works.
ROC-22 RC drilling rig is mainly used for reverse circulation(RC) drilling , water well and observation well drilling, geothermal hole, mini foundation pile hole, etc.
