TT Club, along with ICHCA International, has issued new guidelines on safe slinging of cargo on and off vessels.
Though now more and more cargoes are moved through containers and roll-on roll-off (ro-ro) system. Slings are used less for moving goods on and off vessels.
However, many cargoes in various parts of the world still require individual lifting, and engineering divisions at terminals will continue to use slings in the normal course of their work.
"This is a feature of cargo handling that is often ignored from the safety point of view, yet there are some simple guidelines that can ensure safe cargo handling using slings," said Mr Peregrine Storrs-Fox, TT Club’s Risk Management Director.
The guidelines explain that all slings, whether made from wire rope, chain, fibre rope and man-made fibres or webbing, are marked with a safe working load (SWL).
This refers to the sling being used in a single straight pull, but single slings can also be wrapped around a load in a choke hitch, basket hitch or parallel basket hitch.
It is also possible to have two, three or four-legged sling assemblies.
To determine what the SWL is in each of these slinging applications, a mode factor is applied to the straight pull safe working load.
The guidelines also set out various other principles relating to sling handling, according to Exim News Service.
