As an emerging national brand in China's testing machine industry, Li Zhi Test was born in response to the testing needs of China's construction engineering field of full-size parts and components, structural components, heavy-duty fatigue life testing, and in October 2008, it first undertook the Ministry of Transportation and Highway Research Institute of the development of 200 tons of concrete pulsation fatigue testing machine. The company has always been to meet the requirements of different industries, scientific research, testing institutions, to establish the direction of product development and key technical parameters, through continuous technological innovation in China's high-end mechanical testing equipment level, to serve the country's major infrastructure construction projects as its own responsibility, has been "One Belt, One Road" in the Lao Railway, Indonesia Yawan High Speed Railway, the Nigerian Coastal Railway, the ShuoHuang Railway, 20,000 tons of heavy-duty transportation reconstruction, Hong Kong-Zhuhai-Macao Bridge, National Astronomical Observatory "FAST" Eye in the Sky, the Struggle manned deep submarine and other national key projects to provide high-end mechanical properties of the test equipment, for the China Academy of Building Research developed China's first 400-ton fatigue testing machine for the heavy loads, for the Tongji University to develop the world's first 600-ton fatigue testing machine for large-scale engineering structures, the world's first 200-ton high-speed impact tensile testing machine for third-generation nuclear power plant containment reinforcement and mechanical connectors; for Central South University, the world's first PMW1200-1200 high-pressure, heavy-duty, large displacement bridge fatigue tester; for the China Railway Research Institute, the development of a national invention and patent product PMW800-3 × 500 three-station high-speed railroad rail pulsation fatigue testing machine and TPW-6A six-station elastic bar fatigue testing machine; with the Ministry of Transportation and Highway Research Institute of the development of national patented products SSFT-1200 highway bridge expansion joints mechanical properties of the testing machine; for the China Shipbuilding Science Research Center (702) to develop 0.5-level 3000-ton transducer calibration system; for the China Ship Wuhan Marine Machinery Co. The first WAZD-4500 damper performance test bench and other national major projects in urgent need of scientific research and testing equipment.

Li Zhi Test is China's high-speed railroad bridges, track plates, rail welded joints, rail sleepers, fastener assembly system, bullet (tan) bars, rolling stock springs and other fatigue life test equipment core R & D and manufacturing enterprises, the China Railway Research Institute, the China Railway Inspection and Certification Center, the National Railway Product Quality Supervision and Inspection Center, the Central South University and other rail transit testing organizations of rails, rail sleepers, track plates, springs, fatigue test chamber are all equipped with our equipment. The company has developed high-end mechanical testing equipment with domestic level for the scientific research and quality inspection institutions in the industries of highway, railway, construction, coal, metallurgy, port, nuclear power, universities and so on. While actively serving domestic rail transportation customers, the company has accompanied China's high-speed rail into Kazakhstan, Nigeria, Indonesia, Thailand, Laos and other countries along the "Belt and Road", actively serving the national development strategy.
