How It Works:

Mechanical spring fatigue test machine is a motor, gear driven cam linkage connected reciprocating 

movement to achieve the compression of the spring campaign.

Main function:

1. According to the technical requirements of the spring to adjust the amplitude and frequency of the spring.

2. Preset number of tests automatically shutdown.

3. TPJ-5, 10,20,50 a spring break auto-stop function.

4. It is simple, reliable and stable.
