Regular inspection and maintenance of lifting slings are essential to ensure their safety and longevity. Properly maintained slings are less likely to fail, which helps prevent accidents and injuries. Here are the steps to perform inspection and maintenance of lifting slings:
Inspection:
Pre-Use Inspection:
Before each use, visually inspect the sling for any visible signs of damage or wear.
Look for cuts, tears, fraying, abrasions, broken stitching, knots, or any other irregularities.
Check the sling's identification tag for information such as the WLL, manufacture date, and inspection history.
During Use Inspection:
While lifting a load, monitor the sling for any sudden changes in appearance or behavior, such as stretching, twisting, or unusual noises.
If you notice any abnormalities, stop the lift immediately and inspect the sling further.
Regular Formal Inspection:
Perform a more detailed inspection of the sling at regular intervals, as specified by industry standards or the manufacturer.
This formal inspection involves a thorough examination of the sling's entire length and all components, including fittings and attachments.
Cleaning:
Keep slings clean from dirt, debris, chemicals, and contaminants that can weaken the fibers or corrode metal components.
Follow manufacturer recommendations for cleaning methods, which may include mild detergents and warm water.
Storage:
Store slings in a dry, cool, and clean environment to prevent exposure to moisture and UV radiation.
Avoid storing slings on the ground or in areas where they can be stepped on or run over.
Avoid Sharp Edges:
Protect lifting slings from sharp edges and abrasive surfaces during use. Use protective sleeves or edge guards when necessary.
Proper Handling:
Avoid dragging slings on rough surfaces or using them to drag loads.
Do not twist or kink slings during use, as this can damage the fibers.
Repairs and Maintenance Records:
If damage is detected during inspection, remove the sling from service immediately.
Repairs should only be performed by qualified personnel or professionals with expertise in sling repair.
Keep detailed records of inspections, repairs, and usage history.
Retire Sling When Necessary:
Slings have a finite lifespan, and they should be retired when they reach the end of their service life or when they exhibit irreversible damage.
Follow manufacturer recommendations for retirement criteria.
