ZL-1802 Safety Helmet Chin Strap Strength Side Stiffness Tester (Electric Type)

Main purpose

According to the helmet GB/T2812-2006, GB 2811-2007 production, mainly used to test the lateral rigidity of the helmet and chin strap strength. Widely used in special labor protection supplies supervision and inspection stations, building science research institutes, construction quality inspection stations, power departments and helmet manufacturers.

Main features

1. The main structure is a single-column structure, and the straight line moves up and down to overcome the problem of stuck and slanted when the same type of equipment moves left and right.

2. Integral structure, without the need to change the fixture, can directly switch the lower jaw strength fixture and the lateral rigid fixture.

3, test process touch screen + PLC + special test program control. The program is automatically controlled. The servo motor and controller are used in the motor. The speed does not need to be adjusted manually. The program automatically adjusts according to the test conditions, and the test data and results are automatically judged and processed. (optional computer control)

4, test and maintain the test program automatic closed-loop control, automatic 30S fixed force value to maintain. No need to adjust manually according to the change of force value.

5. Real-time display of force value, time, displacement, deformation, speed, test curve, etc. during the test.

6, large chin with a stretch stroke, stretching up to 500mm, to overcome the lower jaw traction with the force from the adjustment button slippage caused by the deformation of the drawbacks.

Main indicators

1, force value range: 0 ~ 1000N, accuracy 1%.

2, displacement range: 0-500mm, precision 0.01mm.

3, timing range: 0-99min, precision 0.1s.

4. Man-made chin: The diameter of the rigid shaft is 12.5mm ± 0.5mm, and the distance between two axes is 75mm ± 2mm.

5, beam speed: 0-500mm/min when no load, infinitely variable speed can be adjusted. Easy and quick adjustment of position according to the helmet.150N/min, 20N/min, 100N/min, etc. are automatically switched according to the test during the test.

6, lateral rigidity: metal plate hardness 45HRC.

7. Working power: AC220V, 50Hz.
