Archwiliad diogelwch obachyn
1. The bachyn used in the lifting mechanism driven by manpower is tested with 1.5 times the rated load as the inspection load.
2. The bachyn used for the power-driven lifting mechanism shall be tested with 2 times the rated load as the inspection load.
3. Ar ôl ybachynyn cael ei dynnu o'r llwyth arolygu, ni ddylai fod unrhyw ddiffygion nac anffurfiad amlwg, ac ni ddylai'r cynnydd yn y radd agoriadol fod yn fwy na 0.25% o'r maint gwreiddiol.

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