Teftîşa ewlehiyê û standarda qutkirina çengelê

Kontrola ewlehiyê yaçengel
1. The çengel used in the lifting mechanism driven by manpower is tested with 1.5 times the rated load as the inspection load.
2. The çengel used for the power-driven lifting mechanism shall be tested with 2 times the rated load as the inspection load.
3. Piştî kuçengelji barkirina teftîşê tê derxistin, divê kêmasî an deformasyonek diyar tune be, û zêdebûna pileya vekirinê divê ji% 0,25% mezinahiya orîjînal derbas neke.

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

Standardên qirkirinê ji boçengels
Ewçengeldivê gava yek ji van rewşên jêrîn çêbibe were rakirin:

â 'degree Asta vekirinê li gorî mezinahiya orîjînal% 15 zêde dibe;
④The torsion deformation of the çengel body exceeds 10°;
⑤The dangerous section of the çengel or the neck of the çengel is plastically deformed;
⑥The çengel thread is corroded;
⑦When the wear of the çengel bushing reaches 50% of the original size, the bushing should be replaced;
⑧ Dema ku mandrel perçeçengel5% ji mezinahiya orîjînal tê qewirandin, divê mandrel were guheztin.
