1. appearance of test machine

FTM-20 dynamic fatigue testing machine is a kind of electromagnetic excitation resonance type fatigue testing machine. It is controlled by electro-hydraulic servo valve. It runs steadily and reliably. It can set frequency, frequency, waveform, voltage, waveform offset and other parameters. The dynamic fatigue testing machine can be used for fatigue testing of prestressed concrete sleepers in railway and high-speed railway industries. The main components of the dynamic fatigue testing machine are constant pressure servo pump station, linear actuator, full digital control system, main frame, oil distribution module, etc.
