The following mounting instructions must always be
followed to avoid the risk of personal injury or property
damage.
Do not use a hook before reading these mounting
instructions.
1. ABOUT THIS INSTRUCTION
These mounting instructions describes in particular how sling
hooks according to TWN 1340/1, TWN 1840/1, TWN 0855/1,
TWN 0858/1, TWN1841/1, TWN 0859, TWN 0856, TWN 1856,
TWN 0854, TWN 0887, TWN 0889 (TWN = THIELE Works
Standard) are to be safely used for lifting purposes.
The instruction applies analogously to components of identical
design.
To comply with these instructions is essential to help avoid
hazards and increases the reliability and service life of the hooks.
DANGER! Indicates a hazardous
situation which, if not avoided, will
result in death or serious injury.
WARNING! Indicates a hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTION! Indicates a hazardous
situation which, if not avoided, could
result in minor or moderate injury.

not related to physical injury.
Safety Instructions signs indicate
specific safety-related instructions or
procedures.
Chains and accessories marked with the American nominal size
7/32” already corresponded to European nominal size mm.
In order to achieve a better match, the previous nominal size
7/32" is now converted to the new nominal size 1/4”.
The working load limits have now also been adjusted.
DEFINITIONS
Clevis
A U-shaped fitting with pin.
Working load limit (WLL)
The maximum load which a hook is designed to support without
shock-loading.
Read ASME B30.10 „Hooks“.
2. BASIC SAFETY REQUIREMENTS
To prevent the risk of injury never walk or stay under lifted
loads!
The working load limit must not be exceeded!
Hooks as well as lifting and attachment means to be used
must be free from defects!
Working under the influence of drugs, medications
impairing the sense and/or alcohol is strictly forbidden!
•Operators, fitters and maintenance personnel must in
particular observe the mounting and operating instructions
of the chain slings into which the hooks are to be installed as
well as standards ASTM A 906/A 906 M (Standard
Specification for Grade 80 and Grade 100 Alloy Steel Chain
Slings for Overhead Lifting), ASTM A 952/A 952 M (Standard

•The directions given in these mounting instructions and
specified documentations relating to safety, assembly,
operation, inspection, and maintenance must be made
available to persons operating and using the hooks.
•These mounting 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.
•Improper assembly and use may cause personal injury
and/or damage to property.
•Assembly and removal as well as inspection 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 hooks.
•Only lift loads that do not exceed the working load limit of
the corresponding chain sling.
•Never expose hooks to loads exceeding the specified
working load limit.
•Do not use force when mounting/positioning the hooks.
•No one including you (operator) must be in the way of the
moving load (hazard area).
•Do not tip-load a hook.
•Hooks shall have well-functioning safety latches.
•Avoid bending loads to act on chain links and hooks.
•Avoid sharp edges. Use edge protectors or reduce the WLL
by 20 %.
#
•Only lift loads that are freely movable and not attached or
fastened.
•Always monitor a suspended load.
•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 shock loads, e.g. due to abruptly lifting loads with
chain in slack condition.
#
•Usage without working safety elements (cotter pins, dowel
pins) is not permissible.
•Make sure the load can take the forces to be applied without
suffering deformation.
•Hooks must be allowed to move freely in all tensile
directions.
•Put the load only down in flat places/sites where it can be
safely deposited.
•Avoid hooks to get caught under the load.
#
•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 regards grade 100, THIELE does not give its approval to the
assembly of components sourced from different
manufacturers!
As a rule, hooks and chain slings are not permitted for the
transportation of persons.
3. DESCRIPTION AND INTENDED USE
THIELE hooks are exclusively intended as end fittings for the
usage in chain slings according to ASTM A 906/A 906M.
The connection to the sling chain is made directly by the clevis
or indirectly by using connecting links which are assembled to
the eye.
Hooks with eye can also be used within welded chain slings.
Hooks must exclusively be used
•within the limits of their permissible working load limits,
•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.
THIELE hooks meet EC Machinery Directive 2006/42/EC
requirements and feature a safety factor of at least 4 based on
the working load limit.
THIELE hooks are designed to withstand 20 000 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.
They are marked with the corresponding chain size, grade,
manufacturer’s symbol and traceability code.
Hooks with safety device can also be used within lashing chains.
When used within a lashing system the maximum lashing
capacity is obtained by doubling the working load limit.
Any alternating use for lifting and lashing purposes is
impermissible!

6.3 Safety latch
Disassembly by driving the dowel pins out.
Assembling by correct positioning of safety latch together with
spring and driving in the thicker dowel pin by a hammer.
Afterwards the thinner dowel pin has to be driven in, taking care
that the slots positioned adverse. Check the correct operability
of the safety latch.
7. CONDITIONS OF USE
7.1 Normal use
Hooks must always be freely movable when attached to the load
and must not rest on or be supported by other structural parts.
When using hooks without safety ok, e.g. due to operational
necessities, special care is to be taken, and a separate risk
analysis must be prepared.
7.2 Influence of temperature
Using hooks at elevated temperatures will cause the working
load limit to be reduced as indicated below.
Grade Temperature range Remaining WLL

If a hook has been exposed to temperatures exceeding
the maximum values specified, it must not be used
furthermore.
7.3 Environmental influence
Hooks must not be used in environments where acids,
aggressive or corrosive chemicals or their fumes are present.
Hot-dip galvanizing or a galvanic treatment is prohibited.
Hooks with clevis are not intended to be used for abrasive
blasting environments.

9. INSPECTION, MAINTENANCE, DISPOSAL
Inspections and maintenance must be arranged by the owner!
Inspection intervals must be determined by the owner!
Visual inspections must be regularly carried out and
documented by competent and trained persons, at least once a
year or more frequently if the hooks are in heavy duty service.
After three years at the latest they must additionally be
examined for cracks. A load test is not a substitute for this
examination.
The results of the inspection shall be kept in a file that has to be
set up for each chain sling
#
before first use. The register shall
show characteristic data of the chain slings
#
and components as
well as identity details.
Immediately stop using hooks that show the following defects:
•missing or illegible identification/marking,
•deformation, elongation or fractures,
•cuts, notches, cracks, incipient cracks, pinching,
•heating beyond permissible limits,
•severe corrosion,
•broken springs,
•not sufficient working safety devices,
•wear in excess of 10 %, e.g. in the receiving area of the pin
diameter,
•missing or damaged pin locks or removal preventing guards.
Cleaning (e.g. prior to inspections) must not take place by using
flames or methods that might cause hydrogen embrittlement
(e.g. pickling or immersion in acidic solutions).
9.1 Inspection service
THIELE offers inspection, maintenance and repair services
performed by trained and competent personnel.
9.2 Maintenance
Maintenance and repair work must only be performed by
competent and trained persons.
Minor notches and cracks may be eliminated by careful grinding
observing the maximum cross section reduction requirement of
max. 10 % and avoid making more severe cuts or scores.
All maintenance and repair activities must be documented
properly.
9.3 Disposal
All steel components and accessories taken out of service must
be scrapped in accordance with local regulations and provisions.
10. STORAGE
Hooks must be stored properly sorted and in dry conditions at
temperatures between 32 °F and 104 °F.
Do not store in a manner that cause mechanical damage.
