Application:
According to the helmet GB/T2812-2006, GB 2811-2007 ECE R22.05、ECE、EN、ASTM、JIS、SNELLM2015、AS/NZS 2063 production, mainly used to test the lateral rigidity of the helmet and the strength of the lower chin strap. It is widely used in special labor protection supplies supervision and inspection stations, construction science research institutes, construction engineering quality inspection stations, electric power departments and helmet production enterprises.
Feature:
3、 the test process touch screen + PLC + special test program control. Program automatic control, motor using servo motor and controller, speed without manual adjustment, the program automatically adjusted according to the test situation, automatic test data and results of the judgment and processing. (Optional computer control is available)
4 、test hold test program automatic closed-loop control, automatically 30S fixed force value hold. No need to adjust manually according to the change of force value.
5、Real-time display of the force value, time, displacement, deformation, speed, test curve, etc. in the test process.
6、Large chin strap stretching stroke, stretching up to 500mm, to overcome the disadvantage of inaccurate deformation caused by the lower stroke chin strap slipping off from the adjustment buckle.
