Influence of Temperature
The respective temperature range limits must be considered
for all components used. Using chain slings in high
temperatures will cause the Working Load Limit to be reduced
as indicated below.

If the chain slings have been exposed to temperatures
exceeding the maximum values specified they must not be
used furthermore.
7.3
Environmental Influence
Chain slings 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.
7.4
Special Hazardous Conditions
The degree of danger when used in offshore applications, 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.
For applications in abrasive blasting environments short
inspection intervals must be scheduled. Selecting a welded
sling chain assembly of the next bigger nominal size increases
the permissible wear allowance.

GENERAL NOTES ON ATTACHMENT
COMPONENTS
8.1
Connecting Links
In mounted chain slings the chains are, for example, joined to
other components by the use of connecting links. In this way,
components can be mounted the nominal size of which
deviates from that of the chain.
Sizes and grades of sling chains and connecting links must
always coincide!
8.1.1
ASSEMBLY
Install the connecting link halves in the components to be
connected and join both halves.
1. Position split sleeve as shown.
2. Push pin up to the split sleeve,
align pin bevels to suit split
sleeve and drive the pin in using
a hammer.
3. Check to make sure split sleeve
safely embraces the pin
centrally.
8.1.2
DISASSEMBLY
1. Use drift to drive pin out.
2. Remove the split sleeve.
3. Separate connecting link halves from the components they
joined.
A set of drifts according to TWN 0945 is available by Article No.
Z03303.
The split sleeves must only be installed once.
The components to be connected must be able to move freely
within the connecting link half they are placed in.
8.2
Shortening Elements
A shortening element within a chain leg is intended only to
shorten the effective length to optimize the balance of the
whole system.
When using shortening elements, such as for example
shortening hooks or claws, please read the respective
separate operating and/or assembly instructions.
