The first is Jining city. Jining is the most important construction machinery manufacturing base in China. Here, there have factories such as Komatsu, Shantui, Shanshan Reconstruction Machinery, and other main vehicle operation. Shantui is the main factory that produces four rollers and Crawler Chassis assy. And one of Shantui factories is the supplier of Komatsu, which is supported by Komatsu technology and management, with an annual production capacity of 1.4 million rollers, and has passed the global heat treatment certification of Komatsu Osaka, with stable quality and high price. Its crawler has a 70% market share among China’s domestic crawler-type construction machinery and enjoys a reputation. In addition, Komatsu has invested in the construction of the Komatsu Crawler Chassis Company, also in Jining. It mainly produces crawlers and four rollers, and its technology and management cannot be underestimated, the products were mainly exported to other countries. Under the leadership of Komatsu and Shantui, a number of four rollers and one belt factory appeared and formed an industrial group in Jining.

Quanzhou is the largest production base of the construction machinery industry for four rollers and Crawler Chassis assy. With the price and the advantages of a full range of the entire industry as an advantage, the production from Quanzhou is a market share of nearly 80%. The price is low and is synonymous with low-end quality. But recently Quanzhou is also improving the quality successively. There have several good-quality production factories already.
