6. REMOVAL
6.1 Preparations
All components to be installed or used must be in perfect
condition and the relevant working load limits of all parts must
accommodate the respective load to be handled.
6.2 Clevis fastening system
The clevis fastening system only
permits attachment of the nominal
chain size that suits the attachment
component.
6.2.1 ASSEMBLY
•
If necessary, remove dowel pin and
pin.
•
(A) Place end of chain leg between
the lateral clevis elements.
•
(B) Push pin from the side fully
into the clevis and through the
last chain link of the leg.
•
(C) Drive dowel pin fully in (must
not project) to secure the pin. The
slot must face away from the pin.
Check whether the chain runs smoothly!
The dowel pins must only be installed once.
Only connect pins and attachment components of identical
grades. Starting with Ø ½" the pins are marked on the front
end.

•
(A) Drive dowel pin out using
hammer and drift punch
•
(B) Push pin out using a drift
punch.
•
(C) Remove the chain.
1) Suitable drift punches are available by Article No. Z03303.
6.3 Shortening device
One of the short chain legs has to be connected
to the master link, may by a ring shackle as part
of a fixed size master link assembly or by a
connector.
The second short chain leg has to be connected
to a shortening claw or shortening hook with
clevis-type fastening system.
A longer chain leg with a hook or other device
at its end to carry the load has to be mounted
to the ringshackle. This chain leg can be
shortened by the usage of the mounted
shortening claw or shortening hook.
7. CONDITIONS OF USE
7.1 Normal use
A shortening element is only used to shorten a single chain leg
and never to transfer the load to additional chain legs. The
shortened part of the chain leg must remain unloaded.
Therefore, it is not allowed to create a 4-leg chain sling assembly
made of a 2-leg chain sling assembly by adding shortening
devices.
Shortening individual chain legs is indicative of a non-
symmetrical load distribution. In this case, attention is to be paid
to working load limit reductions.
7.2 Shortening hooks
Assembly and disassembly are only carried out in unloaded
condition.
7.2.1 ASSEMBLY
Push the chain link of the chain leg to be shortened past the
hook tip into the slot. If a safety bolt is present, push it back with
the chain or pull it back by hand at the rear edge nut. Make sure
that the lower leg of the chain link inserted into the slot is
positioned near the bottom of the hook and, if present, that the
safety pin above the upper leg of this chain link returns
automatically to its extended safety position.
The chain leg to be loaded can be located either to the right or
left of the central longitudinal plane of the hook.
