Foreword
This document (EN 13889:2003) has been prepared by Technical Committee CEN /TC 168, "Chains, ropes,
webbing, slings and accessories - Safety" the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by December 2003, and conflicting national standards shall be withdrawn at the latest
by December 2003.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EC Directive(s).
For relationship with EC Directive(s), see informative annex ZA, which is an integral part of this document.
Annexes A and C are informative. Annex B is normative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
This European Standard has been prepared to be a harmonised standard to provide one means of conforming with
the essential safety requirements of the Machinery Directive and associated EFTA regulations.
The extent to which hazards are covered is indicated in the scope. In addition, lifting equipment will conform as
appropriate to EN 292 for hazards that are not covered by this standard.
The designation system given in annex C for recording the identifying features of forged steel shackles has been
included in this first edition of this standard as an informative annex. However, should its use become accepted
then the status of the annex will need to be reviewed.
1 Scope
This European Standard specifies requirements for forged steel Dee and bow shackles of grade 6 for general lifting
purposes in a range of working load limits 0,5 t to 25 t maximum.
This standard applies only to those shackles with threaded pins.
Annex A gives information on the safe use of shackles, annex B gives information on types of pins, and annex C
gives an example of a designation system for forged steel shackles.
The hazards covered are identified in clause 4.
2 Normative references
This European Standard incorporates by dated or undated reference provisions from other publications. These
normative references are cited at appropriate places in the text, and the publications are listed hereafter. For dated
references, subsequent amendments to, or revisions of, any of these publications apply to this European Standard
only when incorporated in it by amendment or revision. For undated references the latest edition of the publication
referred to applies (including amendments).

3 Terms and definitions
For the purposes of this European Standard the terms and definitions given in EN 10025: 1990 and the following
apply:
3.1
shackle
a lifting accessory comprising a body and pin as shown in Figures 1 and 2 which are readily separable and can be
used to connect a load to a lifting machine directly or in conjunction with other lifting accessories.
3.2
body
a part of the shackle formed to the shape of a dee or bow and terminating in eyes as shown in Figures 1 and 2.
3.3
pin
a component of circular section which passes through the eyes of the shackle, as shown in Figures 1, 2 and B.1
and which can be readily disassembled.
3.4
dee shackle
a shackle the crown of which forms a semicircle of internal radius half the width, W, between the eyes as shown in
Figure 1.
3.5
bow shackle
a shackle the crown of which forms more than a semicircle of internal radius more than half the width, W, between
the eyes as shown in Figure 2.
3.6
working load limit WLL
maximum mass that a shackle is authorized to sustain in general service
NOTE This term has the same meaning as the term maximum working load used in EN 292-2: 1991, annex A.
3.7
manufacturing proof force MPF
force applied to the shackle during the manufacturing proof test
3.8
breaking force BF
maximum force reached during the static tensile test of a shackle at which the shackle fails to retain the load
3.9
traceability code
series of letters and/or numbers marked on a shackle that enables its manufacturing history, including identity of
the cast of steel used, to be traced
3.10
lot
number of shackles of the same type and dimensions, manufactured during the same production run from the
same cast of steel and subjected to the same heat treatment process
3.11
type W pin
screwed pin with eye and collar and which screws into one eye of the shackle body
3.12
type X pin
bolt type pin with hexagon head, hexagon nut and split cotter pin
3.13
competent person
designated person, suitably trained, qualified by knowledge and practical experience, and with the necessary
instruction to enable the required test and examination to be carried out
NOTE EN ISO 9001 gives guidance on training.
4 Hazards
Accidental release of a load, or release of a load due to failure of shackle puts at risk, either directly or indirectly the
safety or health of those persons within the danger zone.
In order to provide the necessary strength and durability of shackles EN 13889 gives requirements for the design,
manufacture and testing to ensure the specified levels of performance are met.
Since failure can be caused by the incorrect choice of grade and specification of shackle EN 13889 also gives the
requirements for marking and the manufacturer's certificate.
Errors of fitting can also lead to failure and EN 13889 contains dimensional requirements to allow correct fit.
Risk of injury due to sharp edges, sharp angles or rough surfaces when handling is also covered by this standard.
Those aspects of safe use associated with good practice are given in annex A.
Table 1 contains those hazards, which require action to reduce risk identified by risk assessment as being specific
and significant for shackles.
