Sikkerhedskontrol afkrog
1. The krog used in the lifting mechanism driven by manpower is tested with 1.5 times the rated load as the inspection load.
2. The krog used for the power-driven lifting mechanism shall be tested with 2 times the rated load as the inspection load.
3. Efterkrogfjernes fra inspektionsbelastningen, bør der ikke være åbenbare defekter eller deformation, og stigningen i åbningsgraden må ikke overstige 0,25% af den originale størrelse.

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

Skrot standarder forkrogs
Detkrogskal skrottes, når en af ​​følgende situationer opstår:
â ’Knæk;
- Farligt snit på slid når 10% af den originale størrelse;
â ¢ Åbningsgraden øges med 15% i forhold til den originale størrelse;
④The torsion deformation of the krog body exceeds 10°;
⑤The dangerous section of the krog or the neck of the krog is plastically deformed;
⑥The krog thread is corroded;
⑦When the wear of the krog bushing reaches 50% of the original size, the bushing should be replaced;
⑧ Når stykket dornkroger slidt til 5% af den originale størrelse, skal dornen udskiftes.
