Founded in 1992, Zoomlion Co., Ltd. is mainly engaged in the R&D and manufacturing of high-tech equipment such as construction machinery, environmental industry, and agricultural machinery. Zoomlion has successively achieved listing in Shenzhen and Hong Kong, becoming the first A-share listed company in the industry, ranking first in China in construction machinery and sanitation machinery, and ranking among the top three in China in agricultural machinery. However, Zoomlion's performance in excavators is not good, and its performance in various indicators is average, and its after-sales service needs to be improved.
