Intended use
Load capacity: working load limit according to test
certificate or working load limit table in the given
directions of tension – see picture 1.
Admissible operating temperature: -20° to 200°.
Impacts: impacts which occur because of e.g.
acceleration during lifting and lowering can be
unconsidered.
Other: Lifting points have to be mounted only with
the included screw. The body is rotatable 360° and
must be aligned in the permitted direction of tension
before use.
Picture 1: permitted Picture 2: not permitted
Information for use
• Lifting points should be used by a competent
authorised person.
• Visual inspection before first usage (see main-
tenance instruction)
• Before every usage check for damages on screw
and thread – lifting points must be rotatable.
• Load only in the specified direction (see picture 1)
with WLL acc. to table.
• Make sure before each use that the lifting point
is hand tight (by the lock system or an Allen key).
• Please note restriction in application for eventually
appearing difficulties in load.
• Connected lifting gear (e.g. hook) must be flexible
in the ring.
• Lifting points must be stored in a clean and dry
area.
• SN1598 lifting points are not designed to be
rotated under load.
• Do not overload lifting points. A falling down load
may lead to injuries or death!
• Do not use damaged lifting points (see maintenance
instruction) – they can fail in operating conditions –
load can fall down!
Limits of use
When lifting points are used under other conditions
than the one mentioned in Intended use (see above),
restrictions on used must be applied.
• Do not use lifting points in connection with acids,
bases or their steams.
For application in chemical environments, please
contact our technical service.
•Do not load lifting points when they come into
contact with corners or sharp edges!
• Do not lift people!
• If the load distribution is asymmetrical (sling legs
subtend different angles to the vertical), only load
the 2-leg sling with the WLL of a 1-leg sling.
In the case of a 3- or 4-leg lifting sling, it is only
allowed to load it with a maximum WLL of a 2-leg
lifting sling. In case of doubt, it must be supposed
that only one of the legs will carry the entire load.

Mounting instruction
Mounting only by competent authorized person.
Tool-free assembly and disassembly
The cap in pos. 1 (assembly position) has contact with
the screw:
0°
The cap in pos. 2 (input position) does not have any
contact with the screw:
360°
• The equipment, where the lifting points are
mounted on, has to meet the requirements of the
Machinery Directive 2006/42/EC.
•Choose adjustment of lifting points so that you
have a symmetric load. Center of gravity must be
under the lifting point.
• The base material must be of sufficient strength
that the force induced can be absorbed without
deformation.
• Choose lifting points with adequate WLLs –
see table.
• The screwing area must be flat and be provided
with a diameter not smaller than the bottom part
of the lifting point. The threaded hole with
adequate depth must be in the middle and in a
square to ensure that the screw can be screwed
in correctly (blind hole).
Operating manual -- Safety ring bolts, rotatable SN1598
• Minimum screw penetration:
1 x M in steel (M = thread size e.g. M20 =
20 mm)
1.25 x M in cast steel
2 x M in aluminum
• Threaded hole must be cleaned before screwing.
• SN1598 lifting points can also be fixed with an
Allen key.
• If necessary (e.g. if vibrations occur), use liquid
thread adhesives (please note manufacturer’s
instructions).
• Make sure that the adjustment of the lifting point
will not lead to improper loading, e.g. if:
– There is no possibility to align in the direction
of tension
– The direction of tension is not in the foreseen
area acc. to picture 1
• Use only original parts – recognizable by the
marking (WLL, thread).
• It is not allowed to modify the lifting point, e.g.
welding, heat treatments and surface treatments
(galvanising) are prohibited. Also shortening of
screw is forbidden.
• Mount only lifting points free from defects.
• Check used lifting points acc. to maintenance
instruction before application.
• After assembling, lifting points must be able to
rotate properly.
•Do not use any extension when assembling.
Maintenance, Checks, Repairs
• An inspection in accordance with the national
standards must be carried out annually by a tech-
nical expert. If used frequently under a full load
these inspections can be implemented regularly.
We also recommend a crack test every two years.
The screw must be taken out from the body.
• The parts must be free from oil, dirt and rust for
inspection and crack test. Adequate cleaning pro-
cedures are the ones, which do not overheat, hide
failures on surface and cause hydrogen embrittle-
ment or stress crack corrosion.
• During inspection check all parts which can influence
safety and function, – e.g.:
– Cracks, notches, deformation, noticeable signs of
excessive heat
– Abrasion resp. corrosion of more than 10 % of the
cross section
In case of doubt, if the lifting points are damaged,
stop using them and have them examined by an
expert.
Repairs
• Maintenance of the lifting points should only be
carried out by technical experts.
• If small defects like notches or score marks are
visible, they can be carefully removed by using
grinders or files. The repaired area has to merge
smoothly without sudden changes of the cross-
section. When repairing, the cross section must not
decrease of thickness by more than 5 %.
• Welding procedures and heat treatments are pro-
hibited.

4. Distortion of the ring caused by excessive lateral
stress
In case of any noticeable distortion, the lifting point
must be decommissioned.
5. Checking the flap function
Check the flaps for distortion, wear and fault-free func-
tioning. Both flaps must be fully functional – it must
be possible to tighten and disassemble the lifting point
by hand. When fully assembled, it must be possible to
turn the ring smoothly (towards the loading direction).
The flaps must be held in position by the spring and
the pins must not be bent.
In case of malfunctioning exchange the flap set.
6. Screw cracking test
Disassemble the lifting point in accordance with the
opera-ting instructions. The screw must be cleaned and
the thread must be checked for damage, distortion and
correct functio-ning (thread gauge). The marking must
be clearly legible and a magnetic surface crack test
must be performed. Smaller cracks on the screw head
may be repaired by filing, grinding etc. Care must be
taken not to reduce the cross-section by more than
10 %. If in doubt, the screw must be replaced.
7. Checking the sleeve
Check the sleeve for distortion and wear. If any doubts
remain regarding functionality or safety of the lifting
point, we suggest to exchange the sleeve or decommis-
sion the lifting point.
Check that all parts have been mounted correctly and
that the lifting point may once again be released for
safe operation.
Service instructions
General information
The lifting point SN1598 operator must perform a
risk assessment test and take measures to ensure the
safe use of the safety ring bolt, including the deter-
mination of the kind of test to be performed on the
safety ring bolt and its scope. STRACK NORMA recom-
mends that such a test is carried out annually by a
qualified person.
Depending on the conditions of use, tests may also
be performed more frequently. In case of frequent use,
we recommend to perform a cracking test every two
years.
To perform this test, the screw must be removed
from the main casting. For regular checks and for the
cracking test, all parts must be free from oil, dirt and
rust. Only choose a cleaning procedure that does not
overheat, cover up surface defects or cause hydrogen
embritt-lement or stress-corrosion cracking.
When performing a test, all parts must be checked
for damages that could impair safety or function;
e.g. breakages, notches, cracks, distortion, improper
heat impact, wear and tear and/or corrosion of more
than 10 % of the cross-section.
If any doubts remain with regard to functionality or
safety, the lifting point must be decommissioned.
Checking
Safety ringbolts SN1598 must be checked as follows:
1. Check that all parts are in their original condition
--- may be seen from the stamping (load capacity,
screw, thread).
Check that the condition of the product upon delivery
has remained unchanged; i.e. no soldering, heat
treatments or surface treatments have been carried
out. Check that the screw has not been shortened.
In all cases, changes must be agreed to determine
whether the lifting point remains suitable for use.
2. Mount the lifting point according to the operating
instructions
Check that the screw-on surface is in full contact with
the mounting surface. If in doubt, check the screw
and the sleeve for distortions or other signs of over-
stressing and exchange if necessary.
3. Distortion of the ring caused by excessive
vertical stress
If the ring exceeds the measure “e” (inside dimen-
sion of the screw head ring), the lifting point must
be decommissioned.
