Tianjin Yishan Construction Machinery Co., Ltd. (Tianjin Construction Machinery Factory) is the earliest company manufacturing tracked bulldozer in China. In 1958, the first tracked bulldozer of China was manufactured in the company, and in 1993, the company became the first enterprise to sell more than 10 thousand of bulldozers in China. Currently, it is the leading enterprise in the earth moving machinery industry of China. Successively subjected to National Construction Bureau, Machinery Bureau, People's Liberation Army General Logistics Department, and now the company is subjected to Xinxing Ductile Iron Pipes Group Co., Ltd. which is under direct control of state-owned Property Committee of the State Council.

Full ranges of products, Abundant R&D ability
The company is located in Hebei district in Tianjin. The products include more than 40 models of tracked bulldozers categorized in seven series, and hydraulic excavators of two different tonnages. The sales of tracked bulldozers rank top 3 in domestic market. Since January, 1998, the company has passed ISO9001 Quality Management System Certification successively for many times. The company gained the honor of the Demonstration Enterprise for Innovation in 2005. Since 1986, T120 tracked bulldozer has been appointed the listed product by the PLA General Armament Department. The Yishan TY 160 tracked bulldozer launched in 1998 becomes the new generation military construction equipment for Chinese army, which is produced on the base of advanced Komatsu technology.

The company firstly introduced in the internationally advanced bulldozer manufacturing technology for D60 (mechanical drive) and D65 (hydraulic drive) from Komatsu. Featured advanced design, easy operation, high reliability and long service life, the product also have the advantages of high efficiency, large power, low fuel consumption and low noise and wide application. With the lowest ground pressure of only 21kPa, TSC180 wetland bulldozer is the one with the lowest ground pressure in China. The newly launched THS160 utility bulldozer enlargers track width and reduces ground pressure; the performance has been enhanced greatly; the redesigned cab provides more comfortable environment for the operator. Different models of Yishan utility products all meet the variouis requirements of national urbanization construction for the garbage handling equipments.

The company constantly develops and manufactures products of unique features.

The machine has gained national patent certificate, and its performance index has reached advanced international level, and it is the first in the country.

The company has independently developed core technologies on mechanical-electro-hydraulics, and cultivated an excellent R&D team. We constantly improve the R&D environment, and use the simulated experiment design methods like finite element analysis and etc. during the optimization and design, which improves the reliability, availability, and serviceability of the components, and reduces the development cycle of new products, and accelerate products of new generation. We formed a complete set of technology development system which includes development and research, product design, manufacturing technologies, and performance testing. Through bring in, absorption, and innovation, we have constituted the product development system of producing one generation, developing one generation, and planning one generation at the same time.
