WLL values given in the chart apply to steel wire ropes class
6x36 and 6x19 with fiber core with nominal wire durability of
1770 N/mm2
according to EN-PN 12385 standard. Change
of the tensile strength for 1960 N/mm2
increases the WLL
by 10,7%. Using a rope with a steel core will increase the
WLL by another 7,8%. When steel core and rope of bigger
tensile strength is combined, as a result there is an almost
19,5% increase of the WLL.
Spliced slings need at least 5 splices. Length of the splice
should equal at least 15 times the diameter of the rope.
Endings of spliced slings can be additionally secured with
a thermo-shrinkable plastic material. Please ask at the
marketing department for more details.
Rope slings should be conserved in a similar way as ropes,
or other metal tools. We recommend Unolit Spray Oil, for more
information about corrosion click here.
Under no circumstances it is allowed to exceed the WLL. This
value is given on a tag on each loop. Slings with an illegible
tag must not be used, and have to be decommissioned.
User is obliged to inspect slings periodically according to
the PN-EN 13414-2 standard.
See this page where you can find safe temperature ranges
for working with slings, depending on how they are
constructed. Following those directives is obligatory.
When placing an order for slings it is crucial to provide
sling’s length measured according to the criteria from
this page, the WLL (alternatively, after consulting
with the marketing department – construction and diameter
of rope). Sling loops are made according to standards
– all departures from the standard must be indicated while
ordering.
