Two sets of hoisting equipment supplied by Tianjin SIEMAG TECBERG Machinery Co Ltd have successfully passed acceptance testing at the SDE 2# Mine in Indonesia, marking the company’s official entry into the Indonesian market and a key milestone in its expansion across Southeast Asia.
The SDE 2# coal mine, developed by Qinfa Group in South Kalimantan, is the second project within the SDE mining area. With an estimated investment of approximately $300 million, the mine is believed to contain around 293 million tonnes of proven coal reserves and 589 million tonnes of coal resources. Once fully operational, it is expected to achieve an annual production capacity of up to 10 million tonnes. The project’s mining permit (IUP) is valid until May 2034, supporting long-term operations.
The supplied service shaft hoisting system is designed to handle both personnel transport and material movement. It includes two vertical shaft hoisting systems equipped with Koepe winders—one directly driven by a low-speed AC motor with forced air cooling, and the other powered via a gearbox-driven motor. The system reaches a total hoisting depth of 386 metres, while production will be carried out through inclined shafts using conveyor belt systems.
This project represents SIEMAG TECBERG’s first installation in Indonesia. The company noted that the successful acceptance highlights the reliability and adaptability of its technology in hot and humid tropical environments, as well as its engineering and project execution capabilities in demanding international mining conditions. It also expressed appreciation to Qinfa Group for its partnership and signalled interest in further opportunities across Indonesia and the broader Southeast Asian region.
