1 Description and Intended Use
THIELE-Shortening elements (Shortening hooks, Shortening claws,
Shortening devices) are exclusively intented to shorten individual chain legs
within several sling chain assemblies according to EN 818-6.
Shortening elements must only be used within a single loaded chain leg.
Shortening elements must exclusively be used
within the limits of their permissible Working Load Limit,
for permissible attachment methods and inclination angles,
within the temperature limits prescribed,
by trained and authorized persons.
Shortening hooks with safety device can also be used within lashing chain
assemblies according EN 12195.
Any alternating use for lifting and lashing purposes is impermissible!
Shortening elements are as a rule not permitted for the transportation of
persons.
THIELE-Shortening elements meet EG Machinery Directive 2006/42/EG
requirements and feature a safety factor of at least 4 based on Working Load
Limit (WLL).
The shortening elements 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 (WLL) must be reduced
before the parts are put to use.
Shortening elements are marked with nominal chain size and quality grade,
manufacturer’s symbol and traceability code.
2 Safety Notes
Risk of injury!
Never walk or stay under lifted loads!
Make sure to use lifting or lashing
means free from defects.
Operators, fitters, and maintenance personnel must in particular observe the
Operating Instructions of the sling chain assembly into which the shortening
elements are to be installed, documentations DGUV V 1, DGUV R 100-500
Chapter 2.8, DGUV I 209-013 and DGUV I 209-021 issued by the German
Employers’ Liability Insurance Association as well as standard specifications
DIN 685-5 and DIN EN 818-6.
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 Mounting Instructions and specified
documentations relating to safety, assembly, operation, inspection and
maintenance must be made available to the respective persons.
Make sure these Mounting Instructions are available in a place near the
product during the time the equipment is used.
When performing work make sure to wear your personal protective
equipment!
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 and authorized persons.
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 put to use worn-out, bent or damaged shortening elements.
Never expose shortening elements to loads exceeding the specified Working
Load Limit.
When using shortening elements without additional safety elements (e.g.
TWN 0827, TWN 1827 or TWN 0851), special care must be taken and the
correct position of the chain in the shortening element is to be verified for
each individual hoisting operation.
Shortening hooks must not be attached directly to loads, e.g. metal sheets.#
Only chain legs and shortening elements of the same nominal size and
grade may be connected.#
Safety elements must not be excessively stressed or strained operationally.
Do not use force when mounting/positioning the shortening elements.
Do not twist or knot the chains together.
In case of multi-leg sling chain assemblies never allow for inclination angles
of less than 15 ° and in excess of 60 °.
Avoid bending loads to act on chain links and shortening elements.
Make sure to use shortening/grab hooks or claws for chain shortening
purposes.
In case of shortening claws only put loads on the chain exiting the claw
pocket bottom.
During lifting/hoisting make sure your hands or other body parts do not come
into contact with hoisting means. Only remove hoisting means manually (use
your hands).
Avoid impacts, e.g. due to abruptly lifting loads with chain in slack condition.
Usage without working safety elements (cotter pins, dowel pins) is not
permissible.
Shortening elements must be allowed to move freely in all tensile directions.
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!
As regards quality grade 10 THIELE does not give its general approval to
the assembly of components stemming from different manufacturers!
Working under the influence of drugs or alcohol is strictly forbidden!

5 Assembly and Disassembly
5.1 Clevis-type Fastening System
Only chain and component of same nominal size and grade belong
together!
Assembly
If necessary, remove dowel pin and
pin.
(A) Place end of chain leg between
the lateral clevis elements.
(B) Push pin from the side fully into
the clevis and through the last chain
link of the leg.
(C) Drive dowel pin fully in (must not
project) to secure the pin. The slot
must face away from the pin.
Check the chain runs smoothly!
Only connect pins and attachment
components of identical quality grades
(starting with Ø 13 mm the pins are
marked on the front end).
The dowel pins must only be installed once.
Disassembly
Slacken the respective chain.
(A) Drive dowel pin out using hammer
and drift punch.
(B) Push pin out.
(C) Remove the chain.
Suitable drift punchs are available by Article No. Z03303.
5.2 Shortening Device
One of the short chain legs has to be connected to the
master link, may by a ring shackle as part of a fixed sized
master link assembly or by a connector.
The second short chain leg has to be connected to a
shortening claw or shortening hook with clevis-type fastening
system.
A longer chain leg with a hook or other device at its end to
carry the load has to be mounted to the ringshackle. This
chain leg can be shortened be the usage of the mounted
shortening claw or shortening hook.
6 Conditions of Use
6.1 Normal Use
A shortening element is only used to shorten a single chain leg and never to
transfer the load to additional chain legs. The shortened part of the chain leg
must remain unloaded.#
Therefore t is not allowed to create a 4-leg chain sling assembly made of a 2-
leg chain sling assembly by adding shortening devices.
Shortening individual chain legs is indicative of a non-symmetrical load
distribution. In this case, attention is to be paid to WLL reductions.
6.2 Shortening hook #
Assembly and disassembly are only carried out in unloaded condition.
Assembly
Push the chain link of the chain leg to be shortened past the hook tip into the
slot. If a safety bolt is present, push it back with the chain or pull it back by
hand at the rear edge nut. Make sure that the lower leg of the chain link
inserted into the slot is positioned near the bottom of the hook and, if present,
that the safety pin above the upper leg of this chain link returns automatically
to its extended safety position.
The chain leg to be loaded can be located either to the right or left of the
central longitudinal plane of the hook.
Disassembly
If present, pull back the locking pin on the rear knurled nut and lift the
shortened chain leg completely out of the slot of the shortening hook to
remove it.

B10357-B 3 EN-190918
6.3 Shortening claw #
Assembly and disassembly are only carried out in unloaded condition.
Assembly
Push the piece of chain selected for shortening the chain leg to be shortened
into the pocket of the shortening claw. Make sure that the lower curve lies
firmly in the bottom of the pocket. The chain leg area to be loaded with the
component located thereon for attachment to the load (e.g. hook) extends
downwards when the chain is correctly inserted.
Check the correct positioning of the chain link in the pocket for each individual
lifting operation!
Disassembly
Move the chain link in the claw completely out of the claw pocket by lifting the
afore loaded chain leg and pulling it away from the shortening claw. If
necessary, carry out a supporting tilting movement of the shortening claw.
6.4 Influence of Temperature
Using shortening elements at elevated temperatures will cause the Working
Load Limit to be reduced as indicated below.

If the sling shortening elements have been exposed to temperatures
exceeding the maximum values specified they must no longer be used.
6.5 Environmental Influence
Sling chain assemblies 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 as well.

Afterwards remove spring and safety pin.
Assembly
Before working on new assembly please clean the hole.
First put in the spring, afterwards take the safety pin with its thin end into the
spring and push it until the thread is shown on the other side of the hook body.
Check pin and spring can move easily.
Assemble knurled screw and secure it by three punch marks on the thread
against unintended opening.
8 Inspections, Maintenance, Disposal
Inspections and maintenance must be arranged for by the Owner!
Inspection intervals shall be determined by the Owner!
Inspections must be carried out and documented by competent persons
regularly but at least once a year, or more frequently in case of heavy-duty
service. After three years at the latest they must additionally be examined for
cracks. A load test shall never be considered a substitute for this examination.
The results of the inspection shall be entered into a register (DGUV I 209-062
or DGUV I 209-063) to be prepared when the sling chain assembly is first
used. The register will show characteristic data of the chains and components
as well as identity details.
Immediately stop using shortening elements that show the following defects:
missing or illegible identification/marking,
deformation, elongation or fractures of chains or components,
cuts, notches, cracks, incipient cracks, pinching,
heatment beyond permissible limits,
severe corrosion,
reduction of the averaged pin diameter by more than 10 % as mean value
of measurements taken perpendicularly towards each other,
impaired or missing safety elements,
missing or damaged dowel pins.
Inspection Service
THIELE offers inspection, maintenance and repair services by trained and
competent personnel.
Maintenance and Repair
Maintenance and repair work must only be performed by competent persons.
Minor notches and cracks may be eliminated by careful grinding observing the
maximum cross section reduction requirement of 10 % and avoid making more
severe cuts or scores.
All maintenance and repair activities are to be documented.
Disposal
All components and accessories of steel taken out of service are to be
scrapped in line with local regulations and provisions.
9 Storage
Make sure sling chain components are stored in dry locations at temperatures
ranging between 0 °C and +40 °C.
