Explosion-proof hand chain hoist scrap standard: When the following conditions occur in the hoist, it must be immediately stopped from use and scrapped: Main load-bearing components (hook, chain, sprocket shaft) have cracks or severe deformation. Chain wear or elongation exceeds the manufacturer's specified value. Wear amount of dangerous section of hook or opening degree exceeds 10% of original size. Brake mechanism fails to function and cannot be repaired. Explosion-proof housing is severely damaged and cannot be repaired (such as large area damage, severe deformation, crack on explosion-proof surface). Explosion protection level no longer meets current site requirements. Exceeds design service life.
