Single - column Helmet Wearing Device Strength Tester with PLC
Touch Screen
Applicable standards
GB811-2010
Main features
1. The main machine structure is single-column structure, which can
move up and down in a straight line.
2. Extra-large stretch stroke of the lace, stretching up to 500mm,
overcomes the disadvantage of inaccurate deformation caused by the
force of the lower stroke of the lace slipping from the adjusting
buckle.
3. The initial load can be set by itself, and the deformation is
automatically collected after the initial load, without manual
resetting.
4. Touch screen + PLC + special test program control during test.
The program automatic control speed does not need to be manually
adjusted, the program is automatically adjusted according to the
test situation, and the test data and results are automatically
judged and processed.
5. Test hold The test program is automatically closed-loop
controlled, and the constant force value of 30S or 120S is
automatically maintained. There is no need to manually adjust
according to the change of the force value.
6. Real-time display of force value, time, displacement,
deformation, speed, test curve, etc. during the test.
Main purpose
According to the motorcycle helmet GB811-2010, it is mainly used to
test the strength performance of the wearing device of the
motorcycle helmet. It is widely used in related production,
scientific research, quality supervision and testing units of
motorcycle helmets.
Result judgment
According to the regulations of GB811-2010 motorcycle helmets, the
strength performance of the helmet wearing device should meet
1. There shall be no elongation exceeding 25mm, tearing of the
lace, falling off of the connector and loosening of the buckle.
Main indicators
| Force range | 0～2000N, accuracy 1%. |
| Displacement range | 0-500mm, accuracy 0.1mm |
| Timing range | 0-99min, accuracy 0.1s. |
| Artificial chin | Rigid shaft diameter 25mm, two shaft spacing 75mm, shaft length
50mm. |
| Beam speed | 0-500mm/min when no load, stepless speed change can be adjusted. It
is convenient to quickly adjust the position according to the
helmet. |
| Type A and Type B | During the test, Type A 113N/min, Type B 75N/min, etc. are
automatically switched according to the specific conditions of the
test. |
| Power supply | AC220V, 50Hz. |
