Just after the Spring Festival of the Year of the Tiger, Xuzhou Jing'an Heavy Industry Machinery Manufacturing Co., Ltd. delivered its first full rotary drilling rig after the holiday to Shanghai, kicking off its campaign to win 2022.
This JHR-210H full rotary drilling rig stands steadily at its work position on Shanghai Metro Line 4, awaiting the whistle to start work. The five-star red flag hanging on the rig demonstrates the confidence of a major infrastructure country in made-in-China equipment. The Jing'an red of the machine body also signifies that in the new year, Jing'an people will be full of passion, innovate and explore, and make new contributions to the development of China's national industry.

At this construction section of Shanghai Metro Line 24, nearly 50 abandoned old piles are affecting shield tunneling construction. The contractor will use Jing'an full rotary drilling rigs to pull them out one by one over three months, a task that conventional piling rigs cannot accomplish.

Ten years ago, Xuzhou Jing'an Heavy Industry Machinery Manufacturing Co., Ltd. successfully pulled out China's first old pile in Shanghai, which immediately opened up the piling market for its independently developed full rotary drilling rig. Today, with its irreplaceable functions, the full rotary drilling rig is proving its prowess in pile foundation construction, and market demand has been rising year after year. On this basis, Jing'an Heavy Industry has grown into a domestic R&D and production base for full rotary drilling rigs.
