3. Ka dib markiijillaablaga saaro culeyska kormeerka, waa inaysan jirin cillado muuqda ama cillad, iyo kororka heerka furitaanka waa inuusan ka badnaan 0.25% cabbirka asalka ah.
4. Waayojillaabs that have passed the inspection, a mark should be printed in the low-stress area of the jillaab, including the rated lifting weight, factory mark or factory name, inspection mark, production number, etc.
Thejillaabwaa in la tirtiraa marka mid ka mid ah xaaladaha soo socda ay dhacaan:
‘Dillaac;

â ‘degree Shahaadada furitaanka waxaa kordhay 15% marka loo eego cabbirka asalka ah;
④The torsion deformation of the jillaab body exceeds 10°;
⑤The dangerous section of the jillaab or the neck of the jillaab is plastically deformed;
⑥The jillaab thread is corroded;
⑦When the wear of the jillaab bushing reaches 50% of the original size, the bushing should be replaced;
Ԥ Marka mandrel -ka gabalkujillaabwaa la gashaday 5% cabbirka asalka ah, mandrel waa in la beddelaa.
