OPERATING INSTRUCTIONS
RAPID SHORTENING CLAWS
GRADE 100
• These operating instructions must be available in a place
near the product during the time the equipment is used.
Please contact the manufacturer if replacements are
needed. Also see chapter 11.
• During operation work, wear your personal protective
equipment!
• Improper assembly and use may cause personal injury
and/or damage to property.
• Assembly and removal as well as inspections and
maintenance must exclusively be carried out by skilled,
qualified, trained and authorized persons only.
• Structural changes are impermissible (e.g. welding,
bending).
• Operators must carry out a visual inspection and, if
necessary, a functional test of the safety equipment
before each use.
• Never use worn-out, bent or damaged shortening claws.
• Only lift loads that do not exceed the working load limit of
the sling chain assembly.
• Never expose chains and claws to loads exceeding the
specified working load limits.
• Do not use force when mounting/positioning the
attachment components.
• Do not twist or knot the chains together.
• Never guide shortening claws over edges or load them
sideways.
• Avoid sharp edges. Use edge protectors or reduce the
working load limit by 20 %.
• In case of multi-leg sling chain assemblies never allow for
sling angles of less than 30 ° and in excess of 75 °.
• Avoid bending loads to act on shortening claws.
• Do not start lifting before you have made sure the load has
been correctly attached.
• Make sure no one including you (operator) is in the way of
the moving load (hazard area).
• During lifting make sure your hands or other body parts do
not come into contact with lifting means. Only remove
lifting means manually (use your hands).
• Avoid impacts, e.g. due to abruptly lifting loads with chain
in slack condition.
• Never move a suspended load over persons.
• Never cause suspended loads to swing.
• Always monitor a suspended load.
• Put the load only down in flat places/sites where it can be
safely deposited.
• Avoid parts of the sling chain assembly to get caught under
the load.
• Operation without functioning safety devices (dowel pins,
springs, safety latches) is not permitted.

• The shortened part of the chain legs must not be loaded
and not used as an endless chain.
• Shortening claws must be able to align themselves freely in
the loading direction.
• Take care for sufficient place for the personnel to move
when choosing the route of transportation and storage
location. Danger to life and risk of injury by crushing
hazards!
• In the event of doubts or concerns about the proper and
safe use, inspection, maintenance or similar things contact
your safety officer or the manufacturer.
THIELE is not responsible for damage caused by non-
observance of the instructions, rules, standards and notes
indicated!
As regard grade 100, THIELE does not give its approval to the
assembly

manufacturers!
As a rule, RAPID shortening claws are not permitted for the
transportation of persons.
3. DESCRIPTION AND INTENDED USE
RAPID shortening claws according to TWN 1852 are exclusively
intended for shortening individual chain legs of sling chain
assemblies of grade 100 according to ASTM A 906/A 906M.
They can be used anywhere in the chain leg as a permanent or
non-permanent connection.
They are constructed symmetrically in terms of safe handling
and have safety latches against unintentional release of the
chain.
RAPID shortening claws should only be used within one loaded
chain leg and only together with chains according to the
marked nominal size and grade 100.
They are not intended for connecting different chain legs.
RAPID shortening claws must exclusively be used:
•
within the limits of their permissible working load limit,
•
for permissible attachment methods and sling angles,
•
within the temperature limits prescribed,
•
by trained and authorized persons.
Failure to do so may cause serious injury or property damage.
When using RAPID shortening claws within sling chain
assemblies observe their operating instructions. In particular,
the working load limits as a function of the number of chain
legs and angle of inclination are documented here.
