CITIC Heavy Machinery Co., Ltd. has recently achieved significant breakthroughs in the field of large-scale mining equipment, successfully developing and manufacturing the world's largest shaft drilling rig with full independent intellectual property rights. This groundbreaking machine features a drilling diameter of 13 meters, a depth capacity of up to 1,000 meters, and a maximum lifting capacity of 700 tons. The development marks a major milestone for the company, reinforcing its position as a global leader in the research, design, and manufacturing of large-scale drilling rigs.
The working mechanism of this large shaft drilling rig is somewhat similar to that of an oil drilling rig, but it is far more complex in terms of technical content and structural design. It integrates multiple advanced technologies, including mechanical systems, electrical controls, hydraulic operations, and mud circulation systems. Currently, only a handful of countries—such as the United States, Japan, Germany, and China—possess the core technology required to produce such large-scale drilling rigs. CITIC Heavy Machinery stands out as the sole Chinese manufacturer with both the design and production capabilities for large-diameter shaft drilling rigs.
Thanks to its state-level enterprise technology center, which houses top engineering talent and cutting-edge R&D resources, CITIC Heavy Machinery has continuously improved its expertise in large-scale drilling rig design and manufacturing. To date, the company has produced six drilling rigs with diameters exceeding 9 meters, which have been deployed across major coal mines nationwide. These rigs have successfully drilled over 30 large-diameter shafts, significantly contributing to the expansion and efficiency of China’s coal industry.
The introduction of these advanced drilling rigs has enabled the construction of large coal mines even in unstable geological formations, opening new possibilities for resource extraction. Industry experts and users alike have praised the performance of CITIC Heavy Machinery’s shaft drilling rigs, recognizing them as a critical asset in modernizing China’s mining sector. With ongoing innovation and technological leadership, the company continues to shape the future of large-scale mining equipment globally.
Natural Rubber Sponge Series
Our G5 series natural rubber foam is made out of natural rubber harvested from rubber trees, plant-based and latex-allergy friendly natural rubber rather than the traditional petroleum-based and limestone-based neoprene. Compared to the traditional neoprene sheets, the natural rubber wetusits production process saves up to 80% on CO2 emissions in one wetsuit. And our all G5 rubber plantations are 100% FSC® certified. FSC® certified means that buying your new G5 natural rubber wetsuit does not contribute to deforestation, human right violations or abuse of agricultural pesticides. It also means that the hevea rubber – the main ingredient G5 natural rubber foam is only extracted from plantations that preserve ecological integrity and biodiversity. Though only 4% of global rubber plantation area is currently FSC®-certified, well-managed FSC®-certified forest management has the potential to affect a positive environmental and social transformation of the natural rubber sector.
