1) Use double-shaft and guide pillar structure, stable support the rising and falling process, do not appear swing phenomenon

2) Use precise threaded rod to control rising and falling, precisely and quickly to fix position.

3) The swing arm use ≥3g/sec acceleration to fall the test specimen during the dropping process.

4) The machine will not go down automatically when abnormal outage during the test;the swing arm can realize the no pressure state automatically and do not be break away from the machine abnormally.

5) The machine uses oil pressure buffer unit device which will adopt 90% kinetic energy to make the machine working stabled and low noise.
