Common Issues Discovered During a Rigging Inspection
During a rigging inspection, problems or issues with the machinery are thoroughly sought-out. That’s the point of inspection, right? However, there are many common issues discovered that aren’t easily identified and it’s important to point them out because of their commonality.
1- Illegible Identification Tags
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.
2- Damage to Synthetic Slings
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.
3- Broken Wires and Deformed Wire Ropes
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 and although OSHA doesn’t provide proper or clear guidelines for inspections on wire ropes, the person performing the inspection should be able to identify damage.
Performance, Reliability, and Safety
An initial rigging inspection is important because it, first of all, ensures safety. You’ll know whether any of the parts require repair or replacement before damage lets you know. OSHA has clear guidelines as to how and when your rigging needs to be inspected. As a construction company, it’s important to remain compliant with these guidelines. Depending on how frequently rigging is performed, you’ll want to have the hardware inspected to ensure its safe for use.
