In 2015, it was established to undertake all the assets, liabilities, personnel and business of the former Lianyungang Huanghai Machinery Co., Ltd., formerly known as the Northwest Exploration Machinery Factory of the Ministry of Geology and Mineral Resources established in Wushan County, Gansu Province in 1970. In 1995, the whole system was relocated to Lianyungang, Jiangsu Province. city.
H.H. Drill-Tech Drilling Machinery Co., Ltd. is a hi-tech enterprise specializing in design and manufacture geotechnical drilling equipment in China. The company was established in 2015 by undertaking all the assets, liabilities, staff members, employees and the professional business of the former Lianyungang Huanghai Machinery Co., Ltd., originally, it had been the Northwest Exploration Machinery Factory of the Ministry of Geology and Mineral Resources the stated owned enterprise established in Wushan County, Gansu Province in 1970 and the whole factory was relocated to Lianyungang, Jiangsu Province in 1995.
Covering an area of 191,400M2, with construction area of 103,700M2 and more than 450 sets of production and testing equipment/instruments, the company owns production capacity of structural parts welding, machining, heat treatment, painting and assembly. As a large-scale geotechnical drilling equipment manufacturing enterprise in China, our company has strong competitive advantages in the field of medium and deep hole wire line core drilling equipment and in the field of trenchless construction equipment.
After 50 years of development, the company owns now four series of leading products, including more than 80 varieties of models and types. There are the series of core drilling rigs for the application of the depth from 100 to 4,200 meters (328 to 13,776 feet) in the solid mine deposits exploration drilling, engineering geological and hydro geological exploration and for the superficial petroleum and natural gas extraction, mine gallery ventilation and water discharge tunnel drilling;
There are the multi-function series drill rigs applied in shale gas, coalbed methane drilling, superficial petroleum and natural gas exploration, oil-well workover, geothermal water well construction and ultra deep hole core drilling.
The series of engineering drill rigs can be carried out in the quaternary period gravel or hard rock stratum and ground with largest diameter of drilling holes from 0.80m to3.00m diameter in the constructions of bridge, highway, high-rise building, pile foundation drilling.
The horizontal directional drilling serial rigs with the pull capacity from 150kN up to 15000kN can be applied in laying various cables and pipes, including power cable, telecommunication cable, thermodynamic pipeline, gas pipeline and water supplying and drainage pipes, and other variety of pipes to cross river bed, highway, building and other obstacles.
After 50 years of development, the company has accumulated profound knowledge in the industry and key technologies as well; ours was rewarded the first prize of Science and Technology Award of Ministry of Land and Resources in 2013 for "Key Technology and Drilling Rig Series of High Performance Full Hydraulic Geological Drilling Machine". HXY-9B Spindle Core Drilling Rig has completed "the deepest drilling hole for rock gold exploration in China", with the final depth of boring hole at 4,006.17 meters and the final diameter of 75mm, which has pioneered deep drilling for minor diameter drilling holes in solid mineral exploration in China. The largest capacity horizontal directional drill rig with the maximum pullback capacity of 1000 tons has successfully completed the directional crossing of the Yellow River Irrigation Area Project in Qinbei District, Jiaozuo City, Henan Province and the Baodi-Xianghe-Xiji gas transmission pipeline project in Shaanxi-Beijing fourth Line.
In recent years, relying on the two platforms of self-management and agency, our company has tried to expand domestic and oversea markets, our products have been marketed throughout the country, and exported to more than 40 countries and regions in the world.
In the future, under the guidance of the enterprise spirit of "Be loyal to the enterprise, love employees, strive harmoniously and pursue excellence", we will bury ourselves in hard and solid work to strengthen and enlarge our enterprise, make and provide with our refined and strong products, and pursue with perseverance the drilling machinery made by H.H. Drill-Tech to be among the world's top.
With excellent team and excellent equipment, to provide customers with ideal products and value services
