1. The ingwegwe used in the lifting mechanism driven by manpower is tested with 1.5 times the rated load as the inspection load.
2. The ingwegwe used for the power-driven lifting mechanism shall be tested with 2 times the rated load as the inspection load.
3. Ngemuva kwe-ingwegweisuswa kumthwalo wokuhlola, akufanele kube khona ukukhubazeka okusobala noma ukusonteka, futhi ukwanda kwezinga lokuvula akufanele kweqe u-0.25% wosayizi wokuqala.
4. Ngobaingwegwes that have passed the inspection, a mark should be printed in the low-stress area of the ingwegwe, including the rated lifting weight, factory mark or factory name, inspection mark, production number, etc.
I-ingwegwekufanele isulwe lapho kwenzeka esinye sezimo ezilandelayo:
â ‘Ukuqhekeka;
Ukugqoka kwesigaba okuyingozi kufinyelela ku-10% wosayizi wokuqala;
â ‘¢ Izinga lokuvula lenyuswa ngo-15% uma liqhathaniswa nosayizi wokuqala;
④The torsion deformation of the ingwegwe body exceeds 10°;
⑤The dangerous section of the ingwegwe or the neck of the ingwegwe is plastically deformed;
⑥The ingwegwe thread is corroded;
⑦When the wear of the ingwegwe bushing reaches 50% of the original size, the bushing should be replaced;
⑧ Lapho i-mandrel yengcezuingwegweigqokwe ku-5% wosayizi wokuqala, i-mandrel kufanele ithathelwe indawo.
