is a somewhat subjective term. A 3/8" diameter 6x19 wire rope has
the same 'construction flexibility' as a 1" diameter 6x19 rope yet,
for us humans, the 1" diameter rope appears to be far 'stiffer';
it just requires more 'muscle' to bend it around an object.
The requirement for
wire rope sling 'flexibility' may also depend on the application and
may even be dependent on the sling type. A simple single leg sling which
is constantly used in a choker hitch requires more 'flexibility' than
a multiple leg sling with a master link which may get used in a straight
connection between the hook and the load only. On the other hand a 'stiffer'
sling can easily be pushed though under loads, steel bundles, pallets,
Unirope slings come in the following flexibility grades (in order from
'flexible' to 'stiff'):
54 strands, GATOR-FLEX®, 3x3x6x19/36 (Steel Core)
18 strands, TRI-FLEX®, 3x3x6x19/36 (Steel Core)
6 strands, 6x37 Fiber Core
6 strands, 6x36 Steel Core
6 strands, 6x19/26/25 Fiber Core
6 strands, 6x19/26/25 Steel Core
Depending on sling diameter we also carry 8x19 Steel Core, 19x7 and 34x7
rotation resistant types, and various high strength Python® constructions.
Aside from flexibility the other difference between sling rope constructions
is the way the end terminations (or splices) are done. See next page for
