OPERATING INSTRUCTIONS
WELD-ON HOOKS TWN 0850/1

1 DESCRIPTION AND INTENDED USE

Weld-on hooks according to this THIELE company standard (TWN) are intended
for lifting and handling loads and are primarily welded onto earth -moving
machinery, e.g. shovels.
They are firmly connected to the load-bearing component by welding.
The weld-on hooks consist of a forged body and a spring-loaded safety latch.
The weld-on hooks are marked with working load limit, manufacturer's mark, CE
mark and traceability code and are not painted.
They are certified by the German Employer's Liability Insurance Association for
Wood and Metal in accordance with the "Principles for the testing and
certification of attachment hooks for earth-moving machinery in lifting
applications" (GS-OA 15-03).
Weld-on hooks may only be used
• within the permissible working load limit and attachment angle,
• within the permissible temperature limits,
• by trained and authorised persons,
• with mounted and functioning securing systems,
• with properly executed weld seams.
Weld-on hooks meet the requirements of Machinery Directive 2006/42/EC and
have a design factor of 4 in relation to their working load limt (WLL).
THIELE weld-on hooks are designed to withstand 20 000 dynamic load cycles at
maximum loading capacity. For higher workloads (e.g. multi-shift and automated
operations) the loading capacity is to be reduced accordingly.
Eine Verwendung zum Zurren oder für den Personentransport ist nicht zulässig!

2 SAFETY NOTES

Risk of Injury!
Never walk or stay under lifted loads!
Make sure to use weld-on hooks and
hoisting means free from defects.
• Operators, fitters, and maintenance personnel must in particular observe the
Operating Instructions of the used vehicle , vehicle assembly and hoisting
means, documentations DGUV V 1, DGUV R 100-500 Chapter 2.8 and DGUV I
209-013 issued by the German Employers' Liability Insurance Association, as
well as the standard specification DIN 15429.
• In the Federal Republic of Germany, the Operational Safety Ordinance
(BetrSichV) has to be implemented and the Technical Rule for Industrial Safety
TRBS 1201, in particular Annex 1, Chapter 2 "Special regulations for the use of
working equipment for lifting loads" must be observed.
• Outside the Federal Republic of Germany the specific provisions issued locally
in the country where the items are used must also be observed.
• Outside the Federal Republic of Germany the specific provisions issued locally
in the country where the items are used must also be observed.
• The
directions given in these Operating
documentations relating to safety, assembly, operation, inspection, and
maintenance must be made available to the respective persons.
• Make sure these Operating Instructions are available in a place near the product
during the time the equipment is used.
• Please contact the manufacturer if replacements are needed.
• When performing work make sure to wear your personal protective equipment!

• Carry out a visual inspection before each use.
• Operators must carry out a visual inspection and, if necessary, a functional
test of the safety equipment before each use .
• Never put to use worn-out, bent or damaged weld-on hooks or hoisting means.
• Only lift loads the mass of which is less than or equal to the working load limit
of the weld-on hooks.
• Never expose weld-on hooks to loads exceeding the specified working load
limits!
• Do not use force when mounting/positioning the weld-on hooks or hoisting
means.
• Check that the load can withstand the forces including proof forces to be
applied without deformation.
• Do not twist or knot the chains together.
• Avoid sharp edges. Use edge protectors or reduce the working load limit by 20
%.
• Only lift loads that are free to move and are not fastened or anchored.
• Do not apply bending stress to chain links and components .
• Shortening of chain sling legs is only permitted with approved shortening
elements.
• 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/hoisting make sure your hands or other body parts do not come
into contact with hoisting means.
• Remove hoisting means only by hand.
• 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 places/sites where it can be safely deposited.
• Do not catch hoisting means under the load.
• Operation without functioning safety devices is not permitted.
• In the event of doubts about the use, inspection, maintenance or similar things
contact your safety officer or the manufacturer!
THIELE will not be responsible for damage caused through non-observance of
the instructions, rules, standards and notes indicated!
Working under the influence of drugs, medications impairing the sense and/or
alcohol (including residual alcohol) is strictly forbidden!
