One of the first things Inspection Technicians look for when inspecting a rigging and lifting sling is if it has a missing or illegible identification tag. But what do all those markings mean, and why are they important? Hercules SLR rigging experts from Brampton, Ontario are on-hand to explain it all.

Your sling’s identification tag provides you with a wealth of essential information to ensure you are lifting safe including: The manufacture of the sling or where it was most recently repaired, the material of the sling, the working load limit (WLL) of the sling, the serial number, the manufacture’s code or stock number and the type of sling.

This is all information that should be taken into account when creating a lifting plan in order to choose the best type of sling for the job based on the WLL, hitch configuration, and capabilities and different sling angles.

All types of sling will come with an identification tag provided by the manufacturer. Over the lifetime of the sling, it’s important to maintain the tag as best as possible in order to keep it legible. If your tag does become damaged, missing, or illegible the sling should immediately be removed from service.

Keeping up with regular inspections will ensure you are never using a chain sling without a tag in proper condition. If you notice a damaged, missing, or illegible tag before your required inspections -- Simply have the tag replaced. While it is considered a repair, additional proof testing would not be needed at that time (unless otherwise required).

What are the Identification Tag Requirements?

The experts at Hercules SLR in Brampton Ontario are answering some key rigging questions over on the Hercules Group of Company’s social media platforms—And this is one of those questions!
