Chongqing Nantong Haolian Industrial Co., Ltd. has recently completed and delivered two of China's largest 2 MW wind power-increasing gearboxes, marking another significant milestone in the company's new product development. This achievement fills a critical gap in the domestic market for such high-capacity wind turbine components.
Chongqing Gearbox Co., Ltd., a large-scale military enterprise under China Shipbuilding Industry Corporation, specializes in the production of gearboxes, couplings, and shock absorbers. Since 1997, the company has been actively involved in national research projects, including the "600 kW Wind Turbine Gearbox and Transmission System" initiative. In October 1998, it successfully developed the first batch of 600 kW wind power-increasing gearboxes, filling a void in China’s wind energy industry.
The FL600 wind power-increasing gearbox was recognized with the National Torch Program Project Certificate in April 1999 and was later listed as an alternative to imported products in October 2001. These gearboxes have since been deployed across various regions in China, including North, East, South, Northeast, Xinjiang, and Inner Mongolia. Some units have operated safely for nearly 8 years, demonstrating their reliability and performance.
In 2004, the company further expanded its product range by developing 750 kW and 1000 kW wind power transmission gearboxes. That same year, two 600 kW gearboxes were exported to Germany, marking a key step in the company’s international expansion. Today, Chongqing Heavy Tooth Wind Power Gearbox Co., Ltd. offers a full range of wind turbine speed-increasing gearboxes from 1000 kW to 2500 kW, and has achieved mass production for 600 kW, 750 kW, 800 kW, 1000 kW, 1500 kW, and 2000 kW systems.
To better meet market demands and enhance professional configuration in wind power generation, Chongqing Gearbox established Chongqing Heavy Tooth Wind Power Gearbox Co., Ltd. in May 2005. Under the "Eleventh Five-Year Plan," the company is continuously improving its R&D and manufacturing capabilities, aiming to produce over 300 units annually for 1.5 MW and 2 MW wind turbine gearboxes.
This ongoing innovation and expansion highlight the company’s growing influence in both the domestic and global wind energy markets. As the demand for renewable energy continues to rise, Chongqing Heavy Tooth remains at the forefront of technological advancement in wind power transmission solutions.
