Description and Intended Use
Master link assemblies are intended to be built in sling chain assemblies for
lifting of loads according to EN 818-4.
They are prevalently used as upper end fittings to connect the sling chain
assemblies to the crane hooks.
Fixed size master link assemblies have integrated ringshackles for easy
attachments of sling chain and therefore they are predestinated for mounted
sling chain assemblies.
These Mounting Instructions apply to following products:

The master link assemblies meet EG Machinery Directive 2006/42/EG
requirements and feature a safety factor of at least 4 based on Working Load
Limit (WLL).
THIELE master link assemblies 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 WLL must be reduced.
Master link assemblies must exclusively be used
within the limits of their permissible Working Load Limit,
within the temperature limits prescribed,
for permissible attachment methods and inclination angles,
by trained and authorized persons.
Master link assemblies are as a rule not permitted for the transportation of
persons.

Safety Notes
Risk of Injury!
Never walk or stay under lifted loads!
Make sure to use hoisting/
attachment means free from defects.
Operators, fitters and maintenance personnel must in particular observe the
Operating Instructions of the sling chain assembly into which the master link
assemblies are to be installed, documentations DGUV V 1, DGUV R 100-
500 Chapter 2.8, DGUV R 109-004, 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, DIN 5688-3, EN 818-4 and EN 818-6.
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.
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. Please contact the
manufacturer if replacements are needed. See chapter 12.
#
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 master link assemblies.
Never expose master link assemblies to loads exceeding the specified
Working Load Limit.
Do not use force when mounting/positioning the master link assemblies.
Master link assemblies must be allowed to move freely in all tensile
directions.
Avoid bending loads to act on master link assemblies.
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 of fixed site master link assemblies without working safety elements
(dowel pins) is not permissible.
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!

Commissioning
Prior to using the parts for the first time make sure that
the parts comply with the order and have not been damaged,
test certificate, statement of compliance and Mounting Instructions are at
hand,
markings correspond with what is specified in the documentation,
inspection deadlines and the qualified persons for examinations are
determined,
#
visibility and functional testing are carried out and documented,
#
documentations are safely kept in an orderly manner.
Dispose of the packing in an environmentally compatible way according to
local rules.
