DFT-4000 Large tonnage electro - hydraulic servo dynamic testing machine
Description
The DFT-4000 series large-tonnage electro-hydraulic servo dynamic testing machine is mainly used for dynamic and static characteristics test and durability fatigue test of high-strength circular chain and link chain for mining. The test method refers to the relevant requirements specified in the standard "High-strength Round Link Chain for Mines" (GB/T12718-2001). At the same time, it is also suitable for tensile, compression, fatigue and other mechanical performance tests of various materials and parts. This system is currently the largest material dynamic test system in China.
