  • the sleeve(s) (120) can be moved into position to protect the sling from abrasion and cutting which will help to extend the life of the sling (110) and reduce the risk of cutting the sling over sharp edges of a load (L).
  • the protective sleeves (120) are wear sleeves for webbing.
  • the apparatus (100) may include one or more impact indicators (120) such as: pop-stitch impact indicators, formed by folding over and stitching the webbing to form a pop-stitch, which breaks when impacted or loaded; heat signatures or glazing -which can indicate a force and weight applied, melting an area; simple wear indicator with soft metal notches can indicate loading; energy absorbers which after being deployed indicate arrest or loading; deformable indicators can indicate extreme overloading or misapplication of an item (i.e. transversely loaded snaphook).
  • the impact indicators (122) are stitch patterns which hold two pieces of webbing together or capture a metal component. The two sections of webbing are laid together and stitched, usually with a rectangular lock stitch pattern, and the threads used can have a contrasting colour from the webbing. The contrasting thread can provide a visual indication of any damage to the stitch pattern.
  • a user takes the loop formed from the sling (110) and passes it around a load to be lifted such as scaffolding equipment in the form of boards, planks, tubes etc. or the user takes a load and passes it through the loop receiving area (113).
  • the user can then pull the second end (112) further through the fastening device (114) until the loop receiving area is abutting the load (L) holding it securely for lifting.
  • the protective sleeve (120) may be positioned correctly.
