​Every type of rigging device is required to have a tag or form of identification. This includes sling hooks, shackles, chain slings, synthetic slings, and wire rope slings. The tags provide users with the capacity or Working Load Limit (WLL), which tells the user the manufacturer, serial number for traceability, product specifications (material, diameter, and design category), working load limit, and lifting capabilities. It’s no surprise that with use these tags will get dirty, grimy, and possibly fall off. However, in some cases, such as the case with slings, once a tag rips off, it’s no longer useable and must be removed from service.    

​

Synthetic slings have a low heat-resistance, which means they’re not recommended for use in high-heat applications. If there’s evidence of heat damage such as from the sun, the sling will need to be removed and discontinued from use during service. There are special, high-heat resistance slings available but if you have a synthetic sling made from nylon or polyester, you may notice greater damage.  

​

A broken wire rope includes distortion, corrosion, or normal wear and tear. Deformations also fall under the category of damaged and will require servicing. Wire ropes require adequate inspections.​
