CITIC Heavy Machinery Co., Ltd. has recently made new breakthroughs in the field of large-scale mining equipment, successfully designing and manufacturing the world's largest shaft rig with completely independent intellectual property rights. The drilling rig has a diameter of 13 meters, a drilling depth of 1000 meters and a maximum lifting capacity of 700 tons. It has once again set a record for CITIC Heavy Machinery in the industry, marking the world's first-class R&D and manufacturing of large rigs.
The working principle of the large shaft drilling rig is very similar to that of the oil drilling rig, but it is much more complicated than the overall technical content and structural composition. It covers various technologies such as mechanical, electrical, hydraulic and mud circulation. It is reported that only the United States, Japan, Germany and China have the core technology for manufacturing large-size drilling rigs. CITIC Heavy Machinery is the only manufacturer in China that has the design technology and manufacturing technology of large diameter shaft drilling rigs. The emergence of large shaft rigs has made it possible to build large coal mines in unstable formations. According to the opinions of users, the shaft drilling rig of CITIC Heavy Machinery has made a "special contribution" to the Chinese coal industry.
Based on the talents and technological advantages of its state-level enterprise technology center, CITIC Heavy Machinery Co., Ltd. has continuously upgraded the design and manufacture of large-scale drilling rigs in recent years. It is reported that so far, CITIC Heavy Machinery has produced six large drilling rigs with a diameter of more than 9 meters. These rigs have drilled more than 30 large-caliber shafts in major coal mines across the country.
