Safety helmet impact puncture resistance tester

2、 Instrument features

1The instrument is fully automatic controlled by a microcomputer. Adopting a dedicated processing system, the instrument automatically collects dynamic signals, processes and outputs data, and has printing function to automatically record and lock the peak impact force.

2Adopting high-precision dynamic force sensors imported from Germany, with a measuring range20KN.

3Adopting a leak free magnetic adsorption structure, the center position of the safety helmet is automatically located by the hammer and puncture cone.

4Test head mold: Special mold casting1Number and2The number and metal head mold meet the specific requirements of the standard, and can be repaired after being hit, which is much better than the old standard wooden head mold.

5The whole machine adopts European standard aluminum profiles and a frame structure, which provides stronger stability; The electrical circuit adopts a built-in design, with a beautiful structure and a modern sense of technology and texture.

6Impact height:1000mm±5mmAdjust the height with a vertical spiral handle. Convenient height adjustment and easy control; Height measurement is simple and intuitive, greatly improving testing efficiency and accuracy.

7The hammer and puncture hammer can be freely replaced, and the operation is simple.

8Protection system: The newly designed metal protective net and installation link fixing method greatly reduce the possibility of accidents during the test and further improve the safety of the test operation.

9The bottom is equipped with a horizontal testing device to ensure that the test is horizontal and improve the accuracy of the test.

10Impact method: Adopting a free fall form, it simulates the actual usage site in the most realistic way, avoiding complex velocity compensation with guide rails or guided falls, and ensuring the accuracy of testing.

3、 Main technical indicators
