As a rule of thumb (unless indicated otherwise), replace any component whose
wear on any one dimension exceed 2.5% of the original nominal value.
Inspection Log Book
A detailed log book must be kept of all inspections, repairs and modifications
carried out on the equipment as well as a follow up on the wear of major
components like the wire rope cable, the hook, the gear reducer, the drum, etc.
These reports must be conserved for future reference and easily accessible to
members of the inspection, maintenance and repair crews.
Hook Measuring and Discard Criteria
It is recommended to replace any hook showing one or more of the following
signs of wear:
Hook Discard Criteria
1
Missing or illegible working load limit identification
2
Pitting, corrosion, cracks, grooves or deep lines on the hook body
3
Signs of weld or heat damage on the hook body, shank or swivel block
4
Wear on any dimension of the hook body exceeding 10% of the original
value
5
Permanent deformation of the hook opening exceeding 5% of the original
value
ATTENTION
It is the user`s responsibility to measure and record the initial hook
dimensions for future reference, since the shape and exact dimensions of the
hooks vary slightly from one hook to the other.
WARNING
If the hook opening exceeds the acceptable limits replace the hook. DO
NOT attempt to close the hook. The hook strength will be lowered.
