JB-450 Semi-automatic shock absorber impact testing machine

This testing machine is a semi-automatic control testing machine with simple operation and high working efficiency. After breaking the sample, the remaining energy is used to automatically swing the field and prepare for the next impact test. Therefore, its advantages can be better demonstrated in the laboratories that continuously do impact tests and the metallurgical and machinery manufacturing plants that do a large number of impact tests.
 
This equipment is used to measure the shock resistance performance of various shock absorber front forks in the motorcycle industry under dynamic load, so as to judge the properties of samples under dynamic load. The difference between the front energy of the pendulum and the remaining energy after the impact is displayed on the dial to obtain the absorbed work of the sample.
