Cargo Bags / Sling Belts
Belt Slings
Belt Slings is a group of 26 IMPA-coded items (codes 232131–232196) under Cargo Bags / Sling Belts in the Rigging Equipment & General Deck Items section (IMPA 23). All of them are priced per piece. Every item in the list is polyester. The list runs through 4 metric sizes from 25 mm to 75 mm.
Buying guide
Belt slings are flat polyester webbing slings used for lifting stores, spares and finished surfaces that a chain or wire would damage. The IMPA lines in this group are described by webbing width (25, 35, 50 mm and up) and length in metres.
They are raised by the bosun or chief officer for deck and stores lifting, and by the engine department for lifting machinery parts. As accessories for lifting they must carry a marked safe working load and be examined and certified.[1]
How to specify it
The IMPA description gives width and length but not the working load limit, so state the WLL you need, the effective length, the eye type (flat or folded soft eyes) and the number of plies. Polyester webbing and round slings carry a blue sewn-in label giving the maker, year of manufacture, material, working length and WLL; ask for it and for the test certificate.[2]
Polyester slings are colour coded by WLL: 1 t purple (violet), 2 t green, 3 t yellow, 4 t grey, 5 t red, 6 t brown, 8 t blue, 10 t and above orange. Naming the colour and WLL on the requisition stops a supplier quoting a lighter sling of the same width.[2]
Rules and certificates
Each accessory for lifting must be clearly marked with its safe working load, and accessories exposed to deteriorating conditions are thoroughly examined at least every 6 months or under an examination scheme, with a certificate held for each test and thorough examination.[1]
