Rotary drilling rigs are designed to excavate holes through boulder, unconsolidated formations or bedrock. The drilling rigs are usually used for boreholes drilling on pile foundation projects, such as the base construction of railway bridges, road bridges, public works bridges and large buildings. Our rotary drilling rigs are manufactured with industry standard. We provide high quality drilling equipment to our esteemed clients.
Features of Rotary Drilling Rigs
1.Characteristics of this drilling equipment include precision engineering, sturdy construction, high efficient, low energy consumption, excellent performance and longer service life.
2.Rotary drilling rigs undergo several tests on well-defined parameters to ensure their flawlessness and optimum quality.

3.The compressors of the drilling rigs are double-filtered to remove residual oil.
4.The sampler is driven by a free fall winch, saving time with the drill rod method. The sampler may be mounted on drill rods if necessary.
5.Rotary drilling rigs have the capacity to dig a deeper hole in unconsolidated formations with the drilling equipment and drive method.
6.Rotary bits are cooled during cutting by injecting high-flow air, which also evacuate rock cuttings from the borehole and stabilize the borehole while drilling.
7.The high flow can constantly clean the bottom of the boreholes, which allow for consistent contact between drill bit and bedrock.
Zhigao Industriesis H.K Limited has been registered in 2007, however, one of our manufacturing bases in mainland China has been established in 1992, which specialized in the foundation pilling tools and pilling equipment research and supply, especially the rotary pilling industry. Thanks to the fast development of foundation sector in China, our company has been expanded and has more than 100 staff. With an annual turnover in excess of USD 10,000,000, the company is supplying the rotary drilling rig, casing tools, CFA equipment, etc.
