The national standards for seat belts have strict requirements for the use and storage of seat belts as follows:
(1) Seat belts should be hung low and low, pay attention to prevent swing collision. For the use of long ropes of more than 3 m, buffers should be added, except for the slings used for self-locking hooks. (2) The damper, differential speed device and self-locking hook can be used in series.
(3) It is not allowed to knot the rope. It is also not allowed to hang the hook directly on the safety rope and should be hung on the connecting ring.
(4) The various parts on the seat belt shall not be arbitrarily removed. Pay attention to the rope cover when replacing the new rope.
(5) After the seat belt has been used for two years, it will be tested once according to the quantity purchase. The rod is subjected to a static load test and stretched by 5 mm at a tension of 2 206 N. If it is not broken, it can be used continuously. When the seat belt impact test is suspended, the free fall test is carried out with a weight of 80 kg. If it is not broken, the safety belt can be used continuously. For the sampled sample, the safety rope must be replaced before continuing to use.
(6) When using frequent ropes, it is necessary to perform visual inspection frequently. When abnormalities are found, the new ropes should be replaced immediately.
