| YG811D type safety helmet impact resistance puncture tester |
 |
 【Scope of application】 Developed according to the latest national standard of safety helmet GB/T 2812-2006 "Testing Methods for Safety Helmets", it is used to test the impact absorption performance test of safety helmets and the puncture performance test of safety helmets. It is widely used in special labor protection equipment supervision and inspection stations and construction scientific research. Institutes, construction engineering inspection stations, electric power departments, and safety helmet manufacturers. 【Related standards】 GB/T 2812-2006 "Test Methods for Safety Helmets", GB/T 2811-2007 "Safety Helmets" 【technical parameter】 1. Impact drop hammer: the weight is 5-5.01kg, the hammer head is hemispherical, the radius is 48mm, and the material is 45# steel 2. Puncture cone: The mass is 3-3.05kg, the cone angle of the puncture part is 60°, the cone tip diameter is 1mm, the length is 40mm, the maximum diameter is 28mm, and the hardness is HRC45. 3. The height of the falling weight: 1000mm, the height of the falling weight can be adjusted 4. Force measuring system: using dynamic force value sensor, measuring range 0-20KN, corresponding minimum frequency 5kHz, full range ±2.0%, accurate to 1N 5. Equipped with 1# and 2# aluminum-silicon alloy test-specific head molds each (in accordance with GB/T 2812-2006 Appendix A) 6. The release point of the electromagnet can be adjusted up, down, left, and right as needed 7. Bench: The suspension and release of impact drop and puncture drop are controlled by electromagnets to automatically attract and close 8. Base: It has impact resistance and can firmly install the load cell 9. Puncture alarm device: When the puncture cone contacts the head mold, the equipment will sound a whistle and flash a light to indicate 10. LED digital display, accurate to 1N, automatically save the *force value (standard); optional touch screen control, display force value curve (optional) 11. The special guiding system can automatically guide the impact point to ensure that the impact position is the center point of the helmet 12. Dimensions: 550*600*1850mm 13. Weight: 150kg 14. Power supply: AC220V 50Hz |
