Conditions of Use
In mounted sling/suspension chain assemblies the chains are for example
joined to other components by means of connecting links. This way components
can be mounted the nominal size of which deviates from that of the chain.
Trade sizes and quality grades of chain and connecting link must always
coincide!
When attaching components observe correct position of the connecting link.
Relevant forces must act in longitudinal direction.
If two chain legs are arranged in one connecting link half for alternate use,
only one chain leg must be subjected to loads!
Connecting links must not be used in environments where acids, aggressive or
corrosive chemicals or their fumes are present. Hot-dip galvanizing or a galvanic
treatment is prohibited as well.

Should the connecting links be exposed to temperatures exceeding the
maximum values specified they must no longer be used.

Inspection, Maintenance, Disposal
Inspections and maintenance and inspection intervals must be arranged for by
the Owner!
Inspections must be carried out regularly by competent persons and at least
once a year, or more frequently if the links are in heavy-duty service.
After three years at the latest the links must additionally be examined for cracks.
A load test shall never be considered a substitute for this examination.
The condition of all attachment components must be documented in the record
file during these inspections.
The results of the inspection shall be entered into a document to be prepared
when the sling/suspension chain assembly is first used. This document will
show characteristic data of the chains and components as well as identity
details.
Immediately stop using connecting links that show the following defects:
Limited hinging capability (halves get stuck),
Wear in excess of 10%, e.g. in the receiving area of the connecting link halves
and of the pin diameter,
Deformation, elongation, cuts, notches, cracks, pinches,
Links heated beyond permissible limits,
Severe corrosion,
Missing or illegible identification/marking.
Maintenance
Maintenance work must only be performed by competent 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 activities are to be documented.
Inspection Service
THIELE offers inspection, maintenance and repair services by trained and
competent personnel.
Disposal
All components and accessories of steel taken out of service are to be scrapped
in line with local regulations and provisions.
