Large Reverse Counter Raise Boring Rig Two - Cylinder Structure High Precision

AT-2000 Opencast Raise-boring Machine Raise Boring Rig Reverse Counterboring

Main Features:

1. It adopts two-column and two-cylinder structure, which has good overall rigidity, high guiding precision and large bearing capacity. The rig frame is directly anchored to the foundation rock by installation. The gapless connection design of the base enables the rig to stabilize the operation without the support of the top support.

2. The rig adopts full hydraulic drive technology, its specially designed of high torque and infinitely adjustable features allow the rig to operate efficiently in hard rock.

3. The all-position working manipulator can complete the loading and unloading operation of the drill pipe in the whole process, saving staffing and reducing labor intensity.

4. The hydraulic system adopts an integrated design concept that simplifies the hydraulic piping structure with good stability, reliability and ease of maintenance.

Main Technical Parameters:

   Anhui TongGuan Machinery and Technology Co.,Ltd is subsidary to Anhui TongGuan Machinery Co.,Ltd,and its businesses are export & import trade and R&D. Anhui Tongguan Machinery Co., Ltd is located in Tongling city, which once was an ancient copper city in China. The company is a national high-tech enterprise integrating the production, study and research, holding by Tongling Nonferrous Metals Group and shareholding by Changsha Mining Research Institute, Beijing Mining and Metallurgical Research Institute and Anhui Provincial Guarantee Group Corporation.

    At present, the company has formed an industrial system with three major series of mine trackless equipment, mine dewatering & environmental protection equipment and large-scale non-standard equipment for mine smelting. Meanwhile, the company has also expanded to the industrial system of coal, smelting and open air mining. It is the first enterprise in China to develop and produce environmental protection equipment—ceramic vacuum filter. Besides, it is also the first enterprise in China to produce high-pressure ring submersible drilling rig and underground trackless equipment, which is the only company that has the four series of underground mine trackless equipment for rock drilling, shovel loading, transportation trucks and service vehicle.

    The company currently has 67 national patents (including 17 invention patents). It has been identified as a national high-tech enterprise and a national intellectual property pilot unit. The company won the honors of “National Advanced Unit for Patent Work”, “Advanced Unit for National Reemployment”, “High-tech Enterprise of National Key Torch Program” and “National Intellectual Property Pilot Enterprise”, etc. It was awarded the “Underground Trackless Equipment Engineering Technology Center” and the Provincial Enterprise Technology Center and the “Anhui Province High Performance Award” by Anhui Province. It is the implementation unit of the national key environmental protection and practical technology promotion project and the drafters and developers of the industry standards of "Ceramic Filter", "High Pressure Annular Drilling Rig" and "True Service Truck". “Tongguan” scraper was awarded “Anhui Famous Brand Product”; “Tongguan” ceramic vacuum filter and drilling machine were awarded “Anhui Famous Trademark”.

    The company now has an annual output of 400 sets of various equipment and 3,500 tons of non-standard equipment for mining and metallurgy. The products have entered into large domestic mines such as Jiangxi Copper company, Yunnan Copper company, Xinjiang Nonferrous Metals, Shandong Gold group and other major mineral resources such as Gansu, Shaanxi, Hebei, Henan, Fujian, Guangdong and Northeast China, involving non-ferrous, black and non-metallic mines. At the same time, the products are also exported to Russia, Ukraine, Kazakhstan, the Netherlands, India, South Korea, Chile, Niger, the Philippines, Zambia, Chile and other countries.

    The company adheres to the core values of the Group's “Creation realizes the future” and the entrepreneurial spirit of “seeking truth, innovation, cooperation and self-improvement”, striving to be listed at the end of the “13th Five-Year Plan” period and becoming a leading company in the domestic industry.
