Immediately stop using self-locking hooks that show the
following defects:
•
missing or illegible identification/marking,
•
deformation, elongation or fractures,
•
cuts, notches, cracks, incipient cracks, pinching,
•
heating beyond permissible limit,
•
severe corrosion,
•
broken springs,
•
wear in excess of 10 %, e.g. hook attachment area and pin
diameter,
•
excessive gap between the top and bottom sections,
•
less than 50 % overlap between the top section and the tip
of the lower part.
Cleaning (e.g. prior to inspections) must not take place by using
flames or methods that might cause hydrogen embrittlement
(e.g. pickling or immersion in acidic solutions).

A larger gap dimension indicates an overload.
Self-locking hooks with a too large gap dimension may no longer
be used.
Structural modifications to reduce the gap are not permitted.
9.3
Maintenance
Maintenance and repair work must only be performed
by competent and trained persons.
Minor notches and cracks may be eliminated by careful grinding
observing the maximum cross section reduction requirement of
10 % and avoid making more severe cuts or scores.
All maintenance and repair activities are to be documented.
