Color Coding of Lifting Web Slings: A Comprehensive Guide
Description
Know the Color Coding of Lifting Web Slings and SWL of lifting web slings according to EN 1492-1 and EN 1492-2 standards. The guide highlights various web sling color codes, WLLs, and capacities that make it easy for users to select safe and efficient web slings for their lifting operations.
Introduction
Lifting web slings are necessary equipment used in many industries to lift different heavy loads safely. The use and safety requirements of these slings are ensured by following specific color coding per EN 1492-1 (webbing slings) and EN 1492-2 (round slings). This manual will enable you understand the colour code, Safe Working Load (SWL) and Working Load Limits (WLL) of lifting web slings.
Methods to Identify SWL of Web Sling
There are three primary methods to identify the SWL of a web sling:
1. Color Code
The SWL of a lifting web sling is indicated by the color hence ensuring that you can easily differentiate between one type of sling from another. The table below shows how different colors correspond with the weight limits that can be lifted using a given kind of web sling as provided by EN 1492-1 & EN 1492-2:
- One-ton web sling: Violet
- Two-ton web sling: Green
- Three-ton web sling: Yellow
- Four-ton web sling: Grey
- Five-ton web sling: Red
- Six-ton web sling: Brown
- Eight-ton web sling: Blue
- Ten tons or above: Orange
2. Black Stitches
- One back stitch means: 1 ton
- Two back stitches: 2 ton
- Three back stitches: 3 ton
- Four back stitches: 4 ton
- Six back stitches: 6 ton
- Seven back stitches: 7 ton
- Eight back stitches: 8 ton
- Nine black stitches : 9 tons
- Ten warm color stitches:10 tons
- Twelve black stitches : 12 tons
3. Manufacturer Tag
For web slings rated at a WLL of 12 tonnes and above, there are no black strips on the sling itself. Instead, the SWL can be identified by the manufacturer’s tag which is attached to these slings. This label contains all necessary information about the capacity of your web sling so that you can choose it for your work safely.
Understanding SWL and WLL of Web Slings
Safe Working Load (SWL)
The SWL or Working Load Limit (WLL) refers to maximum loads which a web sling can carry without any damage to it. The safe working load is determined for each type of web sling on the basis of its material, construction, and in accordance with EN1492-1 and EN1492-2 norms.
Conclusion
To ensure safety and efficient lifting operation, it is essential to understand the color coding as well as SWL associated with lifting web slings. By following EN14921 and EN14922 set guidelines, you will be able to ascertain that you have a proper web sling for your specific load-lifting needs; thus avoiding accidents and securing your working operations. To know their capacity, check out the manufacturer’s tag on web slings with a WLL of 12 tons and above.
