Kuchengetedza kuongorora kwechirauro
1. The chirauro used in the lifting mechanism driven by manpower is tested with 1.5 times the rated load as the inspection load.
2. The chirauro used for the power-driven lifting mechanism shall be tested with 2 times the rated load as the inspection load.
3. Mushure mechirauroinobviswa pamutoro wekutarisa, hapafanire kuve nehurema hwakajeka kana kushomeka, uye kuwedzera kwedhigirii rekuvhura hakufanirwe kudarika 0.25% yehukuru hwepakutanga.

4. Nokutichirauros that have passed the inspection, a mark should be printed in the low-stress area of the chirauro, including the rated lifting weight, factory mark or factory name, inspection mark, production number, etc.

Scrap zviyero zvechirauros
Iyochirauroinofanira kubviswa kana imwe yeanotevera mamiriro ezvinhu ikaitika:
â ‘Kutsemuka;
Chikamu chine njodzi chinopfeka chinosvika gumi muzana yehukuru hwepakutanga;
â ‘¢ Dhigirii rekuvhura rinowedzerwa ne15% zvichienzaniswa nehukuru hwepakutanga;
④The torsion deformation of the chirauro body exceeds 10°;
⑤The dangerous section of the chirauro or the neck of the chirauro is plastically deformed;
⑥The chirauro thread is corroded;
⑦When the wear of the chirauro bushing reaches 50% of the original size, the bushing should be replaced;
⑧ Kana mandrel echidimbuchirauroyakapfeka kusvika ku5% yehukuru hwepakutanga, mandrel inofanirwa kutsiviwa.
