Components 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 suitable connecting links or attachment components,
• by trained and authorized persons.
Failure to do so may cause serious injury or property damage.
THIELE components meet EC Machinery Directive 2 6/42/EC
requirements and feature a safety factor of at least 4 based on
the working load limit.
They are signed with the corresponding chain size, grade,
manufacturer’s symbol and traceability code.
THIELE components are designed to withstand 2 dynamic
load changes under maximum load conditions. In the event of
higher loads (e.g. multi-shift/automatic operation) the working
load limit must be reduced.
Ringshackles TWN 812 and TWN 1812 as well as swivels TWN
845 may be used in lashing chain assemblies. When used within
a lashing system the lashing capacity (LC) is obtained by doubling
the working load limit.
Any alternating use for lifting and lashing purposes is
impermissible!
4. COMMISSIONING
Prior to using the components for the first time assure that
•the components comply with the order and have not been
damaged,
