It is necessary to ensure that the load is suitable for lifting with a rope sling. The sling must not be able either to damage the load or to suffer damage itself.
If the sling is to be attached to the load, the points used for attachment (e.g. ears and eyelets) must be accessible and suitable for lifting the load.
The mass of the load to be lifted must be determined.
If the mass is not defined, it can be deduced from information from delivery notes, manuals, drawings, etc. If any information is missing, the mass must be determined by the person responsible for lifting.
Once the slinging method and the maximum working load (CMU) have been established, a sling suitable for the load to be lifted and the characteristics of the load itself must be chosen.
As far as possible, the actual diameters of pins, hooks or other components on which non-reinforced eyelets have been used must be no less than twice the diameter of the rope.
You must make sure that the slings are in good condition. Slings found damaged or deteriorated to the extent that they are considered unsafe for use must be removed immediately.
It is necessary to ensure that the load is well balanced for lifting.
Slings should be secured at defined lifting points, when provided.
If the lifting points are not indicated on the load, the position of the centre of gravity must be evaluated.
The type of sling and slinging methods used must ensure that the load does not tip or slip. The grab hook must be positioned directly above the centre of gravity. If this is not possible, special care must be taken when lifting the load.
It must be ensured that the load does not contain loose parts.
If the load includes a certain number of pieces, for example a bundle of tubes, a slinging method must be chosen that ensures all the pieces.
The sling must not be attached to belts or straps unless they are designed in this manner.
