1. Adopt servo motor to lift hammer, with high control accuracy and accurate positioning. When the lifting hammer

    and lifting hammer are in place, there is a process of acceleration and deceleration of the servo motor, which can

    reduce the impact on the motor;

2. Siemens PLC equipped with Taiwan touch screen control has the advantages of high reliability, strong anti dry

    resistance, versatility, adaptability, expansibility, small maintenance workload, etc;

3. It has the functions of automatic sample sending and positioning, easy operation and high working efficiency;

4. The main frame adopts the upper and lower split column structure, and there are four columns in total. The bottom

    plate is made of the whole solid steel plate, which fully guarantees the stability of the testing machine during the

    impact;

5. The hammer body is processed in a separate way, each of which is made of high-strength integral steel plate, with

    high impact strength, so it will not be broken due to casting defects;

6. The hammer body is lifted by the anchor chain. Compared with the ordinary steel wire rope, the elasticity of the

    anchor chain is small, so that the height measurement is more accurate. Moreover, the anchor chain has high

    strength, is not easy to wear, and is safer than the steel wire rope;

7. The hammer grabbing device of the testing machine is a specially designed self-locking device, which will lock itself

    immediately after grabbing the hammer. Under the action of gravity, there will be no accident, and it will not open

    when the power is cut off accidentally, so it has high safety;

8. The sample sending frame of the sample sending device is processed as a whole, without welding and with high

    strength. Equipped with sample clamp block, the clamp block is quenched with high quality steel, with high surface

    hardness and strong wear resistance. Dovetail groove is used between clamp block and clamp block seat for                convenient replacement;

9. Specially designed and customized buffer oil cylinder according to the tearing impact characteristics of the drop

    hammer, with high buffer energy, high impact resistance speed and symmetrical arrangement, can effectively

    absorb the remaining energy of the drop hammer, reduce the impact on the equipment and extend the service life

    of the equipment;

10. It has a sample recovery device, which can take the waste sample out of the testing machine and prevent the tester

     from entering the testing machine to recover the waste sample, which not only improves the working efficiency,

     but also improves the safety of the tester;

11. The drop hammer impact tester has a fully enclosed protective net and multiple safety protection devices, which

     fully guarantees the safety of the tester;

12. The intelligent control system can alarm the following faults: the sample is not in place, the hammer is not self-

      locking, the protective device is not in place, the hammer is not lifted in place, etc.
