Chain sling users can help avoid damage and possible accident by recognizing these 5 improper practices and preventing their occurrence.
- Overloading – can lead to rapid wear, elongation and possible sling failure.
- Improper angle of lift – small angles of lift result in excessive loads being imposed on each leg of the sling. The results on the sling are the same as for overloading.
- Faulty hook-up
- Point loading of hooks. Wedging or forcing the hook point into the loads results in the hook bending and failure. Hooks should not face in toward the load.
- Slipping of unbalanced loads.
- Lifting with twisted or knotted chains can impose loads in excess of rated capacity and spin the load dangerously.
- Impact loading – jerking or snatching loads (shock loading) when lifting can impose loads on the chain in excess of the actual weight of the object being lifted. These dynamic forces can break or damage the sling.
- Improper storage of chain slings – chain slings placed in areas where loads may be deposited on the sling, where traffic can run over the sling or in areas where they are exposed to corrosive action can severely damage the slings.
