Soft (textile) lifting slings
Round slings, webbing slings (eye/eye) and endless webbing slings are mainly used without other lifting components although they can, when needed, with advantage be used in combination with grade 80, grade 100 or other approved lifting components. Textile lifting slings has the advantage of low weight in comparison with their strength and also a soft surface against the item to be lifted. The advantage is less risk for damage on delicate surfaces on the item being lifted. The webbing slings are also more flexible and can be applied a variety of ways. Soft lifting slings produced in accordance with EN 1492-1 and -2 are color-coded for working load limit (WLL).
Round sling with our without seam?
At Forankra AB you find round slings with or without side seam. Round slings with double coating (double layer of protective fabric) are up to 40% more resistant to ware and tear. Round slings with side seam are a bit tighter and stiffer which can be of advantage if e.g. the sling is to be inserted under a pallet. A seamless round sling is in general a bit softer and floats out a bit more to widen the contact surface.
CE-marked lifting sling
Lifting accessories produced after January 1st 1995 must be CE-marked. The CE-marking is a proof of the compliance with the European Machine Directive. User manuals and declaration of conformity must be attached to each delivery.
What is EN 1492-1 and -2?
Lifting slings marked with EN 1492-1 or -2 are produced according these European norms. They are among other things color-coded, tested and in compliance with high requirements. If a sling is in accordance with these norms it is also in compliance with the machine directive.
Calculation of working load limit
Soft lifting slings are color-coded based on the working load (WLL) they are rated for. The WLL is reduced or increased based on how the sling is applied on or around the item to be lifted. See table.
