SUPERFLEX SINGLE SLING WLL

Superflex single slings are used for general lifting purposes where a flexible steel sling is needed.
The WLL is shown in the table in tonnes on 1000kgf – the standard safety factor is 5.

These WLL figures are derived in accordance with AS 1666.1.high quality Ferrules and conforms to DIN 3039.

NOTES ON THESE CALCULATIONS: to conver the list MBF of Superflex cable in kNs to WLL of a Superflex sling in tonnes (1000kgsf) made from that cable, use the following proceedure – divide the MBF by 49.05 (9.81 x 5), then multiply this result by 0.95 to allow for the 5% reduction for sling assembly as required by AS 1666.1 (the all up dividor = 51.5). This provides the WLL for a sling in single fall configuration, and from this all the other configurations
are calculated.
