OPERATING INSTRUCTIONS
CHAIN SLINGS GRADES 80 AND 100
•
The specific safety and operating regulations and standards
issued locally in the country where the items are used must
be observed.
•
The directions given in these Operating Instructions and
specified documentations relating to safety, assembly,
operation, inspection, and maintenance must be made
available to persons operating and using the sling chains.
•
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 13.
•
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 chain slings.
•
Only lift loads that do not exceed the Working Load Limit of
the sling chain assembly.
•
Never expose chains to loads exceeding the specified
Working Load Limits.
•
Position the load hook above the load's center of gravity.
•
Do
not
use
force
attachment components.
•
The load must resist and tolerate the forces to be applied
without suffering deformation.
•
Do not tip-load a hook.
•
Do not twist or knot the chains together.
•
When using shortening elements without additional safety
means (e.g. TWN 0827, TWN 1827, TWN 0851 or TWN
1851), special care must be taken and the correct position of
the chain in the shortening element is to be verified for each
individual lifting operation.
•
Avoid sharp edges. Use edge protectors or reduce the
Working Load Limit by 20 %.
•
The Working Load Limit must be reduced in the following
cases
o if the load is not balanced symmetrically,
o if the chain is used in choke hitch applications,
o when higher temperatures prevail,
o when high dynamic and cyclic loads arise (automated or
multi-shift operation),

when
mounting/positioning the
o when lifting magnets are employed.
•
In case of multi-leg chain slings never allow sling angles of
less than 30° and in excess of 75°.
•
Hooks shall have well-functioning safety latches.
•
Attach unused chain legs to the suspension link.
•
Suspension links must be allowed to move freely in the
crane hook.
•
Only lift loads that are freely movable and not attached or
fastened.
•
Do not bend loads to act on chain links and components.
•
Safety elements must not be stressed or strained
operationally.
•
Use only shortening/grab hooks or claws for chain
shortening purposes.
•
Shortening hooks must not be attached directly to loads, e.g.
metal sheets.
•
For shortening claws, only the chain coming out of the
bottom of the claw pocket must be loaded.
•
Only chain legs and shortening elements of the same
nominal size and grade may be connected.
•
Shortening elements must be allowed to move freely in all
tensile directions.
•
Safeguard chain slings to prevent slipping when using the
basket hitch application method.
•
Do not start lifting before you have made sure the load has
been correctly attached and balanced.
•
No one including you (operator) must be in the way of the
moving load (hazard area).
•
During lifting your hands or other body parts must 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 down only in flat places/sites where it can be
safely deposited.
•
Do not allow the sling chain assembly getting caught under
the load.
•
Assume for sufficient space 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.
