On April 29, the Zhejiang Machinery Industry Federation held a membership meeting, at which the 2020 Zhejiang Machinery Industry Science and Technology Award was commended. The high-end product "One-way anti-bending heavy-duty cascade chain" of Hangzhou Ziqiang Chain Transmission Co., Ltd., a subsidiary of the group, won the third prize. This is the nine consecutive years that Donghua Group's product innovation project has won the Zhejiang Machinery Science and Technology Award. It is also the only high-end product of the chain drive enterprise in the province's machinery industry science and technology innovation awards in 2020.
The one-way anti-bending heavy-duty cascade chain has passed the provincial-level industrial new product acceptance and was identified as a leading domestic high-end innovative product by an expert meeting. It has obtained 5 patents during the product development process. This product is a high-precision, high-carrying chain in the escalator chain, suitable for high-end loading and unloading logistics equipment such as heavy-duty/public transportation escalators, ultra-high-lift escalators, etc., especially suitable for applications with unidirectional anti-bending functions It is a key safety component of a heavy-duty escalator, and fully meets the high requirements of high-end escalator equipment such as high strength, good rigidity, stable operation, excellent wear resistance and convenience for later maintenance.
The development of this product has filled the gap in the domestic high-end product field. It has been successfully applied to the ultra-high-lift escalator at the Badaling Great Wall Station of the Beijing-Zhangjiakou High-speed Railway, a national key project, and its lifting height reached a record 42 meters (equivalent to 15 floors). The building height), the transmission distance is up to 100 meters, and it has been applied in batches to Turkish subway facilities projects, and the market prospect is broad.
The Zhejiang Machinery Industry Science and Technology Award is an important science and technology award set up for the machinery industry of the province. Donghua has won awards for high-end products every year, demonstrating that Donghua, as a domestic industry benchmark, has made contributions to promote the development of China's high-end equipment and the development of China's chain drive industry. New contributions.
