7.10 Hooks

7.10.1 General

Check hooks for deformation or cracks. Hooks must be replaced if throat opening has increased by more

than 15%, or if throat opening has more than 10-degree twist from plane of straight hook.

Figure 20. Measuring Hook Deformation

Due to many types and sizes of hooks that can be furnished and/or specified by the user / owner, it is

recommended that user / owner measure the actual throat opening of hook as originally furnished. See

Figure 20. Record the throat dimension on above sketch. Retain as a permanent record. This record can

then be used for determining when hook must be replaced due to deformation or excessive throat opening.

CAUTION: Abuse or overloading of hoist is indicated when any hook is twisted or has a

throat opening in excess of normal. Other load bearing components SHALL be checked for

damage.

CAUTION: Safety latches SHALL be replaced if missing, bent, or broken.

CAUTION: A safety latch SHALL function properly at all times.
