GRADES 80 AND 100
9. INSPECTION, MAINTENANCE, DISPOSAL
9.1 General
Inspections and maintenance must be arranged by the owner!
Inspection intervals must be determined by the owner!
Visual inspections must be regularly carried out and
documented by competent and trained persons, at least once a
year or more frequently if the shortening elements are in heavy
duty service. After three years at the latest they must
additionally be examined for cracks. A load test is not a
substitute for this examination.
The results of the inspection shall be kept in a file that has to be
set up for each sling chain before first use. The register shall
show characteristic data of the chains and components as well
as identity details.
Immediately stop using shortening elements that show the
following defects:
• missing or illegible identification/marking
• deformation, elongation or fractures of chains or
components
• cuts, notches, cracks, incipient cracks, pinching
• links heated beyond permissible limit
• severe corrosion
• reduction of the averaged pin diameter by more than 10 %
as mean value of measurements taken perpendicularly
towards each other
• impaired or missing safety systems
• missing or damaged dowel pins.
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).
9.2 Inspection service
THIELE offers inspection maintenance and repair services by
trained and competent personnel. Please contact us for further

9.3 Maintenance and repair
Maintenance and repair work must only be performed
by competent and trained persons.
The movable safety pins and bolts should be checked regularly
for their function and lubricated with multi-purpose oil or grease
when installed. Then operate the securing elements several
times to spread the lubricant.

Minor notches and cracks may be eliminated by careful grinding
observing the maximum cross section reduction requirement of
max. 10 % and avoid making more severe cuts or scores.
All maintenance and repair activities must be documented
properly.

All steel components and accessories taken out of service must
be scrapped in accordance with local regulations and provisions.
10. STORAGE
Shortening elements must be stored properly sorted and in dry
conditions at temperatures between 32 °F and 104 °F.
