Section 1: Application of Electro-hydraulic Servo Spring Fatigue Testing Machine

The PWS-100/200/300/500 series electro-hydraulic servo spring fatigue tester is primarily used for fatigue life testing of various locomotive helical springs and air springs. It can also be adapted for dynamic and static performance research of various materials and components by replacing different test accessories as needed.
