en.Wedoany.com Reported - Mining services provider Thiess Group deployed its fourth Liebherr R 9800 hydraulic excavator in June 2026 at the Lake Vermont coal mine, owned by its long-term client Jellinbah Group, located in the Bowen Basin, Queensland, Australia. This move aims to enhance the mine's loading capacity and support the project's long-term production strategy. The excavator is configured with a face shovel, bringing Thiess Group's global fleet of R 9800 units to a total of 10.
Thiess Group is one of the world's leading mining services contractors, covering mine operations, engineering design, and operational management. Its partnership with Liebherr spans over three decades. Lake Vermont is an open-cut coal mine owned by the Lake Vermont Joint Venture, with Jellinbah Resources as the majority shareholder. In July 2025, Thiess Group signed a three-year contract extension worth $2.3 billion with Jellinbah Group to continue providing comprehensive mining services at the mine.
The R 9800 is Liebherr's largest flagship excavator. The deployed unit is equipped with a 47.5-cubic-meter bucket and powered by two Cummins QSK60 engines, delivering a combined output of 4,000 horsepower (approximately 2,983 kilowatts). Nick Brown, Regional General Manager of Thiess Eastern Australia, stated that the excavator can excavate approximately 3,000 bank cubic metres per hour, translating to an annual production capacity of 16.8 million bank cubic metres. He also noted that the additional excavator has increased the mine's loading capacity, helping to deliver strong operational results for long-term clients.
This deployment further solidifies Thiess Group's leading position in the application of large-scale mining equipment. With its fleet of R 9800 units, the company continues to support operational excellence in global projects through scale, reliability, and high performance.
