The two Asian Games venues, Keqiao Yangshan Rock Climbing Center and Fuyang Yinhu Sports Center, have installed intelligent modular system skylights. The window drive chains supporting the intelligent skylights are all supplied by Taicang Hengjiu Chain Transmission Co., Ltd., a subsidiary of Hengjiu Group.

The chain has a straight-edge structure and a large thrust. It is mainly used in heavy-duty intelligent window openers for functions such as daily ventilation, adequate lighting, firefighting and smoke exhaust. 

As chain-type window openers are used in various fields, the reliability requirements and service life requirements of the chain, which is one of the key components, are also increasing. We focus on providing high-quality window opener chain products to domestic and foreign clients, and develop and produce window opener chains with high precision, long life and corrosion resistance.
