2. General description
The SA shackle is a lifting shackle consisting of a
U-shaped body, a bolt, a nut and a safety cotter
pin.
The SA shackle is designed, manufactured and
tested to be a sling component in accordance to
EN 1677-1. Type tests include deformation test,
static tensile test and fatigue test. Gunnebo
Industries manufacturing test regime includes
proof loading 100% of the lot.
The SA shackle is marked as follows.
On the bow:
manufacturer identification (GBO or GBO SWE)
product name, size and material grade (8)
CE mark
WLL1in tonnes
batch/traceability code2
On the bolt:
material grade (8)
batch/traceability code
Detailed technical data as dimensions, working
load limits (WLL) etc. can be downloaded from
www.gunneboindustries.com.
Shackles can be used for lifting only when the
user has a valid certificate. Gunnebo Industries
issues a manufacturer´s certificate according to
EN 1677-1 and a 3.1 material certificate acc. to
EN 10204. Authorized resellers may provide their
own documentation, but will be able to provide
the original certificates upon request.
1The maximum working load a lifting accessory or lifting
assembly can be subjected to. For the SA shackle the
stated WLL is valid when the shackle is loaded in a
straight direction.
2 The traceability code consists of letters and numbers
that identifies exactly which plant the product was
made in, the year and the batch. This gives the ability to
trace the product back through the manufacturing
process, all the way back to the specific raw material.

3. Intended use and restrictions
Intended use
Bolt, nut, and cotter pin type shackles like the
SA Shackle provide the most secure pin (bolt)
arrangement. They are suitable for applications
where the shackle is semi-permanent with
infrequent removal.
The SA range is designed to be a sling
component and applies to the normal sizes and
WLLs for grade 8 chain slings according to EN
818-4. The SA Shackle can also be used in steel
wire rope slings and textile slings.
The SA shackle can be used as an end
component in slings or lugs.
It can also be used as a connecting component in
different constructions, provided that the
necessary technical calculations have been
taken, with regards to load and environmental
factors.
This instruction primarily covers use of shackles
for lifting.
General limitations in the use of the SA Shackle
Never modify, repair or reshape the product
by welding, heating or bending as this will
affect the nominal WLL.
Never heat treat the product as this may
affect the WLL.
The product must not be galvanized or
subject to any plating process without the
approval of the manufacturer.
The product must not be used in alkaline or
acidic conditions.
The product must not be exposed to
aggressive chemicals, acids and vapours.
Use in exceptionally hazardous conditions
The rating of lifting accessories in European
Standards assumes the absence of exceptionally
hazardous conditions. Exceptionally hazardous
conditions include offshore activities, the lifting
of persons and lifting of potentially dangerous
loads such as molten metals, corrosive materials
or fissile materials. In such cases the degree of
hazard should be assessed by a competent
person and the working load limit adjusted
accordingly.
WLL reduction at elevated temperatures
The general service temperature is -40 °C to
+200 °C. For temperatures higher than +200° C,
the following apply:
Service
temperature
New load capacity in % of
original WLL
200-300 °C
90%
300-400 °C
75%
> 400 °C
Not allowed
If the service temperature exceeds 200 °C, the
corrosion protection of the bolt will be lost.
Side loading is not allowed
The SA shackle is designed to carry the load at
the center/bottom of the bow, and evenly
distributed on the shackle bolt.
Fatigue
It is important to realize that fatigue failure can
occur even if the shackle’s WLL has not been
exceeded. Scenarios, in which the shackle is
subjected to variable load over a prolonged
period of time, will carry the risk of inducing
fatigue. Consider this when dimensioning and
deciding service intervals.
Additional marking
If markings such as project code, serial number
etc. are added it must be done in a way that
does not reduce the shackles strength, corrosion
resistance or the legibility of the manufacturer's
own marking. Provided these conditions are met,
we recommend the following methods of
marking: marking tape, engraving tool or low
stress punches.

4. Assembly
When the SA product is incorporated as a part of
a sling it must be part of the certification and
WLL rating of the complete sling.
The assembly of the SA shackle may only be
executed by a qualified person.
When assembling the SA shackle observe the
following:
Verify that all markings are readable and that
all parts of the shackle are of the correct type
and size.
The bolt should not be tightened in a way
that prevents the bolt from rotating freely. In
most cases, hand tightening will be sufficient.
Ensure that the bolt and nut is properly
secured with the safety cotter pin attached.
A poor-fitting between the shackle bow and
bolt may be due to the bolt being bent,
damaged threads or misalignment of the bolt
holes. Under these circumstances the
schackel must not be used.
5. User instructions
The SA shackle is only to be used after reading
and understanding this manual.
For further recommendations regarding safe use
of the shackle in sling applications, the user is
referred to Gunnebo Industries’ instruction for
safe use of slings.
Verification prior to first use
Before first use ensure that:
the SA Shackle is precisely as ordered.
the manufacturer’s certificate is in order.
the identification and working load limit
marking on the SA Shackle correspond to the
information on the certificate.
full details of the shackle are recorded.
Inspection prior to each use
Before each use the SA Shackle must be
inspected for obvious damage or deterioration.
The inspection should be done in accordance
with local regulations but the items listed in
section 6 Inspection should as a minimum always
be controlled. If there is any doubt with regards
to these criteria being met, the shackle must not
be used for a lifting operation.
Before loading
Know the weight of the load and the centre
of gravity.
Check the conformity of the load with the
WLL of the lifting equipment for the specific
working configuration.
Ensure that the SA shackle has been correctly
assembled in accordance with section 4.
Ensure that no obstacles will obstruct the lift
and prepare the landing site.

General instructions for safe use
Avoid side loading
The SA shackle should be fitted to the load in
a manner that allows the shackle body to take
the load in a true line along its centreline to
avoid undue bending stresses which will
reduce the load capacity of the shackle.
Avoid eccentric load distribution
It is recommended to distribute the load
evenly across the total length of the shackle
bolt. Loose distance spacers may be used on
both ends of the bolt.
However, under no circumstances should the
opening be forced together, or parts be
welded onto the bolt to facilitate centering of
the load Such actions will have a negative
impact on the shackles mechanical
properties.
Avoid unstable loads
Avoid contact with sharp edges that could
damage the shackle.
Avoid rotation of the shackle bolt
Avoid applications where, due to load
movement, the shackle bolt can roll and possible
unscrew.
When securing the load, the bow of the
shackle should be put into the running side of
a choke.
Use of shackle with multi-leg slings
Multiple sling legs should be applied to the
shackle body. Due consideration should be
given to the effect of the angle between the
sling legs. The stated WLL is valid for leg
angles up to 120°. Larger leg angles should be
avoided.
The illustration to the left is taken from the book Sikker
bruk av løfteredskap (Safe Use of Lifting Equipment),
and are used with the publisher’s permission (www.Lsi-
bok.no ).
Use of two connecting shackles
If two shackles are fitted together, it is
generally recommended to connect the bows.
Use of shackle with fiber and textile slings
When fitting shackles together with fiber and
textile lifting slings, ensure that the contact
diameter is according to the sling
manufacturer’s recommendations. If
necessary, use a bushing on the shackle bolt
to achieve the necessary contact diameter.
Hoisting effect
When a shackle is used to secure the top
block of a set of rope blocks the load on this
shackle is increased by the value of the
hoisting effect.
End of use/Disposal
The SA shackle shackles shall be sorted /
scrapped as general steel scrap.

6. Maintenance
Inspection
During service lifting equipment are subjected to
conditions which affect their safety. It is
therefore necessary to ensure that the
equipment should be safe for continued use.
The SA shackle should be withdrawn from
service and referred to a competent person for
thorough examination if any of the following are
observed:
The schackle markings are illegible, i.e.
information about the identification and/or
the working load limit.
More than 10% reduction of the original bow
or bolt diameter dimension at any point.
Incomplete bolt engagement.
The threads of the bolt and/or the shackle
body are damaged.
Cuts, nicks, gouges, cracks, excessive pitting
or corrosion, heat discoloration, bent or
distorted components or any other defects.
Thorough examination
A thorough examination should be carried out by
a competent person at intervals not exceeding
six months. The inspection interval should be
less where deemed necessary taking into
consideration:
local-, national-, or branch-specific regulation.
the service condition of the shackle.
eventual use in demanding environments
(e.g. corrosive or extreme temperature).
eventual use where the shackle is subjected
to repeated loads that may induce metal
fatigue.
Records of such examinations should be
maintained.
Prior to the examination the SA Shackle should
be cleaned so it is free from oil, dirt and rust.
Any cleaning method which does not damage
the parent metal is acceptable. Methods to avoid
are those using acids, overheating, removal of
metal or movement of metal which may cover
cracks or surface defects.
Repair
Repairs must only be done by a competent
person who has the knowledge and technical
skills. The shackle shall only be returned to
service after approval by a designated person.
Records of repairs should be maintained.
Any replacement component or part of the chain
sling should be in accordance with the
appropriate European Standard for that
component or part. Use only original Gunnebo
spare parts.
Components that are cracked, visibly distorted
or twisted, severely corroded or have deposits
which cannot be removed should be discarded
and replaced.
Minor damage such as nicks and gouges may be
removed by careful grinding or filing. The surface
should blend smoothly into the adjacent
material without abrupt change of section. The
complete removal of the damage should not
reduce the thickness of the section at that point
to less than the manufacturer’s specified
minimum dimensions or by more than 10 % of
nominal thickness of the section.
