The TSP4-500KN spring fatigue testing machine also called spring fatigue cycle life tester or spring endurance test rigs made by Wintime Machinery Co., Ltd is created for validate and evaluate a variety of shock absorber or heavy duty springs such as locomotive springs、car springs、helical suspension spring、compression springs the performance and endurance life of bearing under the required speed & load . This testing machine mainly use computer and software to control the whole system, which can make the accuracy more precise. The hydraulic cylinder is imported from Germany, which is high flow, good circularity and high availability. This machine can be used to test the heavy duty springs of haulage motor. This machine can adopt the electro-hydraulic servo testing system to operate. The all parts of equipment can be maintained and repaired. The main functions of this machine is as follows, it can use fixed deformation or fixed load. Measurement system can be automatic zero, automatic calibration. Computer real-time display test amplitude, test frequency, the number of fatigue. The load capacity is up to 500KN, and the test space is about 600mm(wide)* 1700mm(length), which can be adjust up and down. The max.test amplitude is ±40mm, and the frequency is about 0.1Hz to 4Hz. The maximum power should be 380 v AC,110 KW.More details about TSP4-500KN Large Spring Fatigue Testing Machine,please search Wintime Machinery Co.,Ltd on internet or search Vickey Tang on Facebook.
