Hook checks (See Fig. 5 and Table 2)
Opening dimension A on the hooks is important. A hook with too large a maximum dimension has
been exposed to overloading or overheating. It therefore does not have the necessary load capacity.
The hooks may also have been exposed to long-term wear (dimension B).

Table 2 Hook dimensions
Defective hooks must be replaced before using the lever hoist again.
Hooks must be discarded and replaced if:
•
the maximum I value is exceeded (according to Table 2)
•
the minimum K value falls short (according to Table 2)
•
the hook is cracked, deformed or otherwise damaged.
