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

2. LCD display, frequency and the number of tests according to your requirment to enter the program, auto-complete.

3. Preset the number of tests and automatically shut down.

4. Consists of motor, reducer to connecting with cams to drive connecting rod for reciprocating motion to achieve the compression of the spring

5. The operator can achieve high load, high frequency, low consumption, thereby reducing the test time andreduce the testing costs.
