DISASSEMBLY
•
Slacken the respective chain leg.
•
(A) Drive dowel pin out using
hammer and drift punch
1)
.
•
(B) Push pin out using a drift
punch.
•
(C) Remove the chain.
Suitable drift punches are available by article no. Z03303.
6.3
Bolt assembly TWN 0861
A)
Move the bolt (1) through both
holes in the shackle ends and see
to it that the two grooves in the
bolt are positioned concentrically
with the dowel pin holes in the
shackle body.
B)
Insert the dowel pins (2). Make
sure the slot faces away from the
bolt towards the shackle bow.
6.4
Bolt assembly TWN 0862 and TWN 0897
A)
Fully insert the bolt (1) through both
shackle boreholes.
B)
Retain the bolt with a suitable nut
(2) and tighten the nut so as to be
hand-tight using an appropriate tool.
Make sure bolt and nut are evenly
seated against the shackle body.
C)
Finally, insert the cotter pin (3) in
the respective hole in the bolt
to secure the connection.

CONDITIONS OF USE
7.1
Normal use
Shackles must not be exposed to bending loads; make sure
eccentric loads are avoided.
Shackles must be able to move freely. Supporting of shackles
on other parts is not permitted.
Take care that
•
incorrect arrangements are avoided, e.g. eccentric loads,
•
damage of lifting or lashing accessories, e.g. by sharp edges,
is not possible,
•
the shackles can be reached easily for fitting/unhinging
lifting or lashing accessories.

Influence of temperature
The respective temperature range limits must be considered
for all components used.
Using chain coupling shackles in high temperatures will cause
the working load limit to be reduced as indicated below.
Temperature range
Remaining WLL
-40 °C ≤ t ≤ 205 °C
-40 °F ≤ t ≤ 400 °F
100 %
205 °C < t ≤ 300 °C
400 °F < t ≤ 572 °F
90 %
300 °C < t ≤ 400 °C
572 °F < t ≤ 752 °F
75 %
If a shackle has been exposed to temperatures exceeding
the maximum values specified, it must not be used
furthermore.
7.3
Environmental influence
Chain Coupling Shackles must not be used in environments
where acids, aggressive or corrosive chemicals or their fumes
are present.
Hot-dip galvanizing or a galvanic treatment is prohibited as
well. Chain coupling shackles are not intended for applications
in abrasive blasting environments.
7.4
Especially hazardous conditions
The degree of danger when used for the lifting of hazardous
loads, such as for example liquid metal or similar, risk
potentials must be assessed by a competent person in the form
of a risk analysis. Any additional rules and directives must be
followed in this case.
