Iniúchadh sábháilteachta arcrúca
1. The crúca used in the lifting mechanism driven by manpower is tested with 1.5 times the rated load as the inspection load.
2. The crúca used for the power-driven lifting mechanism shall be tested with 2 times the rated load as the inspection load.
3. Tar éis ancrúcaa bhaint den ualach cigireachta, níor cheart go mbeadh aon lochtanna nó dífhoirmiú follasach ann, agus níor cheart go mbeadh an méadú ar an gcéim oscailte níos mó ná 0.25% den mhéid bunaidh.

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

Caighdeáin scrapála docrúcas
Tá ancrúcaba chóir a scriosadh nuair a tharlaíonn ceann de na cásanna seo a leanas:
â ‘Crack;
â € ¡Sroicheann caitheamh coda contúirteach 10% den mhéid bunaidh;
â ‘¢ Méadaítear an chéim tosaigh 15% i gcomparáid leis an méid bunaidh;
④The torsion deformation of the crúca body exceeds 10°;
⑤The dangerous section of the crúca or the neck of the crúca is plastically deformed;
⑥The crúca thread is corroded;
⑦When the wear of the crúca bushing reaches 50% of the original size, the bushing should be replaced;
⑧ Nuair a bheidh mandrel an phíosacrúcacaite go 5% den mhéid bunaidh, ba chóir an mandrel a athsholáthar.
