CDA-101-1 Safety Helmet Impact Puncture Tester

Product Overview:

1、 Main purpose

The CDA-101-1 safety helmet impact puncture resistance tester is based onGB/T2812-2006 and GB 2811-2007 are mainly used for testing the impact absorption performance and puncture performance of safety helmets. Widely used in special labor protection equipment supervision and inspection stations, building science research institutes, construction engineering quality inspection stations, power departments, and safety helmet production enterprises.

2、 Host structure

1. The main structure of the equipment adopts four 80 * 40 European standard aluminum alloy profiles, which have a beautiful appearance and ensure the stability and reliability of the equipment.

2. The protective net adopts a customized protective plate structure, with buffer strip layers around the protective plate, which has better performance than a separate protective net structure.

3. The base is made of 10mm thick 45 # integral material, which has impact resistance and can firmly install force sensors.

4. The hammer head suction device adopts a universal structure to ensure that the axis of the hammer and the axis of the sensor coincide, and the falling point of the hammer is the center of the safety helmet.

5. The suction release point can be vertically raised and lowered to adjust the testing height, and the vertical lifting structure can ensure that the hammer is used in a horizontal state.

6. Equipped with 1 # and 1 # magnesium aluminum alloy test head mold each, which can be repaired; One impact hammer and one puncture cone are used for the experiment.

7. Adopting the form of free fall, it simulates the actual use of the site in a realistic way, avoiding complex velocity compensation with guide rails or guided falls, and ensuring the accuracy of the test.
