1 Introduction THIELE round link chains and attachment components form part of sling chains and are conducive to the safe transportation of loads.
These operating instructions describe how round short-link chains according to TWN 0805 grade 8 and TWN 1805 grade XL as well as connecting links according to TWN 0829 and TWN 1829 are safely used for hoisting purposes.
TWN = THIELE-Werksnorm (THIELE Shop Standard)
The present operating manual is a translation of the German-language original document within the meaning of 2006/42/EG.
B08182-A Seite 3 EN-180610
2 Intended Use Round link chains according to TWN 0805 and TWN 1805 as well as the pertinent attachment components and connecting links are in-tended for use as chain slings as per EN 818-4 for the purpose of attachment and hoisting of loads.
Chain slings must exclusively be used
� if weight and gravity center of the load are known, � within the limits of their permissible working load limit, � for permissible attachment methods and inclination angles, � within the temperature limits prescribed, � with suitable connecting links, attachment components or short-
ening elements, � by trained and authorized persons. Connecting links must only be used with load-carrying legs.
3 Storage Make sure chain slings are stored properly sorted, suspended and in dry locations at temperatures ranging between 0 °C and +40 °C.
4 Safety Notes
4.1 Personnel
� Operators must in particular observe the instructions for use, the German Employers’ Liability Insurance Association’s regulations BGR 500, chapter 2.8, BGR 150, BGI 556, BGI 622, BGV-D6, regulation PAS 1061 as well as standard specifications DIN EN 818-1, DIN EN 818-2, DIN EN 818-4, DIN EN 818-6 and DIN EN 1677.
� Mounting and removal as well as inspection and maintenance must exclusively be carried out by authorized persons.
Outside the Federal Republic of Germany the specific provisions issued locally in the country where the items are used must also be observed.
B08182-A Page 4 EN-180610
4.2 Product Safety
Risk of Injury
Make sure to use chain slings free from defects.
� Handling chain slings improperly will endanger life and assets. � Never use worn-out, bent or damaged chain slings (see Pt. 10.1). � Never make structural changes to chain slings (e.g. by welding or
bending).
4.3 Use
Risk of Injury
Never walk or stay under lifted loads!
� Only lift loads the weight of which is less than or equal to the working load limit of the chain sling system.
� Never expose chains to loads exceeding the specified working load limit.
� Note that the working load limits will reduce in the following cases: - the load is not spread symmetrically, - chain is used in choked hitch applications (WLL will reduce by 20%), - when higher temperatures prevail, - when high dynamic and cyclic loads arise, - when lifting magnets are employed.
� In case of multi-leg chain slings never allow for inclination angles of less than15° and in excess of 60°.
� Do not use force when mounting/positioning the attachment com-ponents.
� Do not start lifting before you have made sure the load has been correctly attached.
� Make sure nobody enters or stays in the immediate danger zone where suspended loads are handled.
� Never move a suspended load over persons. � When lifting loads make sure your hands or other body parts do
not come into contact with the chain sling. � Never cause suspended loads to swing. � Make sure to consult the respective manufacturers if you intend
to combine chains of different quality grade and/or chains pro-duced by different manufacturers.
� Attach unused chain legs to the suspension link. � Do not twist the chains.
B08182-A Seite 5 EN-180610
� Avoid sharp edges; use edge protectors. � Do not tip-load a hook. � Suspension links must be allowed to move freely in the crane
hook. � Avoid bending loads to act on chain links and components. � Make sure to use shortening/grab hooks or claws for chain short-
ening purposes. � Safeguard chain slings to prevent slipping when using the basket
hitch application method. � Always monitor a suspended load. � Avoid impacts, e.g. due to abruptly lifting loads with chain in slack
condition.

8 Conditions of Use
8.1 Use under Normal Conditions
When attaching components observe correct position of the con-necting link. Relevant forces must act in longitudinal direction.
Never load a connecting link with 2 load-carrying chain legs.
8.2 Use at Elevated Temperatures
Using chain slings at elevated temperatures will cause the working load limit to be reduced as indicated below.
Temperature Range Working Load Limit
-40 °C to 200 °C 100 %
200 °C to 300 °C 90 %
Grade 8
300 °C to 400 °C 75 %
Temperature Range Working Load Limit
-30 °C to 200 °C 100 %
200 °C to 300 °C 90 %
Grade XL
300 °C to 380 °C 60 %
When the chains are to be used within other temperature ranges please get in touch with the manufacturer.
Should the chain slings be exposed to temperatures exceeding the maximum values specified they must no longer be used.
B08182-A Seite 15 EN-180610
8.3 Use under Adverse Environmental Conditions
Never use the chains if adverse chemical conditions exist.

10 Maintenance
10.1 Inspections
Check the chain slings visually at regular intervals. The results of the inspection shall be entered into a register (BGI 879) to be prepared when the chain sling is first used. The register will show characteris-tic data of the chains and components as well as identity details.
An inspection must be carried out at least once a year or more fre-quent if the rings are in heavy-duty service. After three years at the latest the chains must additionally be examined for cracks.
The condition of the chain and other components must be docu-mented during these inspections.
If items require repair the respective cause of damage and remedial steps need to be documented.
Immediately stop using connecting links that show the following de-fects: � limited hinging capability (halves get stuck), � wear in excess of 10%, e.g. in the receiving area of the connect-
ing link halves and of the pin diameter.
Number of legs WLL at max. inclination angle (60° in this case)

Immediately stop using chain slings that show the following defects: � Deformation/expansion. � Cuts, notches, cracks, incipient cracks, pinching. � Chains heated beyond permissible limits. � Severe corrosion. � Wear exceeding 10% (e.g. average chain link thickness). � Identification marks are unreadable. � Impaired safety systems, for example if the hook safety latch is
defect. � Hook widening by more than 10%. 10.2 Repairs
Only use THIELE spare parts. Only use original THIELE pins, sleeves, dowel pins, safety latches etc. for attachment components because these meet the specific requirements prescribed. Replace without delay any chain legs and components that show signs of damage. Do not repair individual links, instead replace complete chain legs only. Make sure welded chain slings are exclusively re-paired by the manufacturer.
