Product description
The FWS series is manufactured and testet by CERTEX Danmark A/S, Olievej 4, DK-6700 Esbjerg, Tel. [phone]
The manufacturing, testing and calculation is according to Machinerydirective 2006/42/EC, and has been
witnessed by DNV GL.
The wire slings are solely designed for liing equipment and must be used as shown in the load diagram
below. The wire slings are calculated with a safety factor of minimum 5:1
The wire slings must not be used for basket-li with an angle exceeding 60°.
The wire slings must not be used for liing people.
Load diagram
* The working diameter is determined by test results for u-li and laced li and must be complied with to meet SF 5:1
All FWS wireslings in this series are marked in ferrule with WLL and date of manufacturing. Additional calculations/
tests on WLL are available for documentation of the above load diagram including the 5:1 safety factor.
!IMPORTANT:
Do not exceed the WLL/capacity and follow the instructions on the labeling.

Visualizing bending diameter D/d
Dierent types of lis.
Eye length must not be smaller
than twice the object diameter.
e.g. hook or shackle.
The diameter of the shackle
has to be as wide as possible.
Recommended shackles* for
straight li:
FWS0950 - 1,5 T shackle
FWS1600 - 2 T shackle
FWS2500 - 3,25 T shackle
FWS3200 - 4,75 T shackle
FWS4800 - 6,50 T shackle
FWS5800 - 8,5 T shackle
FWS8000 - 9,5 T shackle
FWS11000 - 12 T shackle
SF: 5:1
* Van Beest GP G-4163
When the li is a hitch li,
then it is very important that
the minimum diameter com-
plies with the table to reach
the sling SF 5:1.
See table on page 2.
If the shackle or other object has
a small diameter, then the max
capacity of the sling is reduced
signicantly.
Fx. hitch li with FWS0950 with
115 mm installation diameter, then
the sling is WLL 1900 kg SF 5:1
Hitch li with FWS0950 with
installation diameter 45 mm, then
the sling has 1900 kg but lower SF.
WLL reduced to 1520 kg, to keep
the SF: 5:1. Se table on page 2.
It’s better to use a larger shackle
or object to get a large working
diameter and therefore get SF
5:1.
Se table on page 2.

When the Flat Braided sling is used as basket sling, with both eyes in the hook, or correct sized shackle,
and it has an angle 0–45
o
from vertical.The max load must not exceed 1,4 x WLL, as marked on the sling.
Protection and distribution of weight
Always make sure to place the load correct in the sling, to prevent chock aect.
It’s always important to protect the edges against sharp edges. It can cause the cuts in the wire, and
damaged the sling lifetime and the slings capacity. It’s also important to have as large round edges as
possible, to have a diameter large enough. Working diameter in Load diagram on page 2 has to be followed
to ensure SF 5:1

1. Two eyes on a hook may
only be done acc. to the illu-
stration.
Recommendations when using flat braided wire sling
4. Liing where the item is
between the eyes may only
take place if the requirements
for working diameter are met:
To avoid creating sharp edges.
3. If there is a need to assem-
ble two wires, then it should
be done acc. to the illustrati-
on.
2. If shackles are to be used
with the wire sling, wide body
shackles should be used.
Also observe the diameter.
Ensure a larger radius around
the wire eyes.
6. Correct, without twist when
liing.

1. Do not hook between the
braids
Is not suitable for the purpose,
and weakens the wire sling.
Improper use of Flat Braided Wire Sling
If the sling is attached to a hook or shackles, the hook MUST be classied as at least 1xWLL flat braided
sling.
2. Do not hook between the
eyes of the sling.
Hook only in the liing eyes
The item you li can slip in
the hook. Can have fatal con-
sequences. May damage wire
sling.
4. Do not li where the item is
standing vertically, as in the
picture
The item may slip out, and thus
be lost.
9. Do not li in such a way
that the wire may cut at an
edge
Damages the wire sling so it can
break.
8. The wire sling must not be
used for personal liing
The wire sling is not suitable
for the purpose. Dangerous.
5. Do not wrap the wire sling
around itself
This damages the wire sling.
7. Do not connect the wire
sling with other slings/
chains/wire sling
Wires, chains or wire slings
can damage each other.
6. Do not make a knot on the
wire sling
This damages the wire sling.
3. The eyes of the sling must
not cross each other, as
shown in the drawing
Under load, the wires can cut
into each other. This will result
in breakage of the wire.

Improper use of Flat Braided Wire Sling
10. Do not li so that a shack-
le is squeezed around an item
Large stress occurs, which re-
sults in the wire being dama-
ged. The item being lied may
slip in the shackle.
11. Do not kink when liing
The wire sling is damaged and
thereby loses strength.
Warnings when using wire sling
11. When liing, make sure
that all personnel have a safe
distance
And also that there are no
objects under the liing zone.
12. Do not twist when liing
The wire sling is damaged and
thereby loses strength.

Instructions for use and safety
All lis using the wire slings must be planned, possibly, according to the individual instructions.
The personal who is using the liing gear, should be trained and instructed in safe use and safe work.
The user is obliged to familiarise himself with the national requirements.
This document must be available to users for planning the li.
As a minimum planning must include:
1. Choosing the correct wire sling, according to the load diagram.
(when using more than one wire sling WLL and length must be the same).
2. Checking the WLL as well as the date on the sling (must be present).
3. Checking the weight of the load and the balance.
4. Checking for no sharp edges and that it is installed with correct working diameter.
5. The condition of the wire sling (must be checked for defects before and aer use).
6. Securing and the actual li (make sure if there are special requirements to training).
7. No twisting of the sling (see page 6 and 8)
At no time during use must the wire sling be:
• Overloaded.
• Twisted.
• Exposed to shock impacts .
• Exposed toor to very sharp edges.
If this can not be avoided, the sling must not be used again until it has been inspected by an expert
IOne must use an appropriate protection if the sling is used around sharp edges. One must show caution
during use and pay attention to whether the protection or sling slides.
Steel wires, in general, must not be unnecessarily exposed to damaging chemicals, e.g. acid, lime etc.
General visual control must be carried out before every use of the wire sling. If the sling is signicantly
damaged or worn it must be discarded immediately.
The wire sling must be discarded when, the following points apply:
• the individual strands are worn and this has an eect on the nominal diameter of the strands in relation
to the liing capacity. Check for wear due to friction on the individual wires. Especially where the sling is
bent
• the individual strand is not worn or there are wire breaks that aect the strap’s liing capacity
• the number of breaches on a rotation length exceeds 10
• there are kinks (i.e. a loop that is pulled out )
• the sling is flattened or edged
• the wires in a strand are bend, e.g. due to exposure to sharp edges
• the sling is damaged by rust or chemical exposure
And / or other damages that questions the ability of the wire sling.

Maintenance
Liing slings must be kept in a good condition and undergo thorough examination by a competent person
at least every 12 months. Local regulations might stipulate more frequent examination interval.
When inspecting and maintaining the wire sling it is important to pay attention to the critical places e.g.
eye /sling deformation.
If a wire sling has been exposed to damaging chemicals a particularly thorough examination may be ne-
cessary to reveal possible damages.
Wire slings must, if possible, be kept in a dry, airy place.
Information
Instructions should be according to this “instruction for use” and should include all safety actions deman-
ded on how to hook.
Before using the liing gear, the instructions for use should be read and understood. It’s attended as help
to get a well and safe use of the gear. The instructions of use are containing information on how the liing
gear is working in a safe and correct way.
If the Liing gear is used in correct compliance with these instructions, then danger and accidents can be avoided.
Every personal using the liing gear should read and act in correct compliance to instructions for use.
We also refer to all national instructions and laws on sites.
IMPORTANT! – WLL CAPACITY MUST NOT BE EXCEEDED AND INSTRUCTIONS ON THE MARKING HAS TO BE FOLLOWED.
