3. DESCRIPTION AND INTENDED USE
THIELE Chain coupling shackles are intended as end fittings of
chain sling assemblies. The chain strands are to be fitted
directly to the clevis. Shackles of TWN 861 are intended to be
mounted once to be left on the load permanently.
Shackles must only be used
•within the limits of their permissible working load limit,
•for permissible attachment methods and sling angles,
•within the temperature limits prescribed,
•with their original bolts and dowel pins of appropriate size,
•by trained and authorized persons.
Failure to do so may cause serious injury or property damage.
THIELE-Chain coupling shackles meet EG Machinery Directive
2 6/42/EG requirements and feature a safety factor of at
least 4 based on working load limit (WLL).
THIELE shackles are designed to withstand 2 dynamic load
changes under maximum load conditions. In the event of
higher loads (e.g. multi-shift/automatic operation, magnetic
spreaders) the working load limit must be reduced.
Generally, they are marked with the associated chain size and
grade, manufacturer’s symbol and traceability code.
Shackles must only be used with a single loaded chain leg.
Shackles can also be used within lashing chain assemblies.
When used within a lashing system the maximum lashing
capacity (LC) is obtained by doubling the working load limit.
Any alternating use for lifting and lashing purposes is
impermissible!

8. INSPECTION, MAINTENANCE, DISPOSAL
Inspections and maintenance must be arranged by the owner!
Inspection intervals shall 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 shackles 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 shackle before first used. The register will
show characteristic data of the shackles as well as identity
details.
Immediately stop using chain coupling shackles that show the
following defects:
•missing or illegible identification/marking,
•deformation, elongation or fractures,
•cuts, notches, cracks, incipient cracks, pinching,
•damaged threads,
•heating beyond permissible limit,
•severe corrosion,
•impaired or missing safety systems,
•wear in excess of 1 %, e.g. in the receiving area of the pin
diameter,
•missing or damaged pin locks or removal preventing guards.
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).
8.1 Inspection service
THIELE offers inspection, maintenance and repair services by
trained and competent personnel.
8.2 Maintenance
Maintenance and epai wo k must only be pe fo med by
competent and t ained pe sons.
Minor notches and cracks may be eliminated by careful
grinding observing the maximum cross section reduction
requirement of 1 % and avoid making more severe cuts or
scores. All maintenance and repair activities must be
documented properly.
8.3 Disposa
All components and accessories of steel taken out of service
must be scrapped in accordance with local regulations and
provisions.
