A flat webbing sling AS 1353 is a type of lifting sling designed to lift heavy loads safely and efficiently. It is made of high-strength synthetic fibers that are woven together to create a flexible and durable sling.
AS 1353 is an Australian standard that specifies the requirements for flat webbing slings used for general lifting purposes. The standard outlines the materials, construction, and testing requirements for flat webbing slings to ensure their safety and performance.
Flat webbing slings AS 1353 typically have a maximum load capacity ranging from 1 ton to 10 tons, depending on the width and length of the sling. They are designed to be lightweight and easy to handle, making them ideal for use in a variety of industries, including construction, manufacturing, and transportation.
One of the advantages of flat webbing slings AS 1353 is their flexibility, which allows them to conform to the shape of the load being lifted, reducing the risk of damage to the load. They are also resistant to abrasion and UV radiation, which helps to extend their lifespan and maintain their strength over time.
It is important to follow proper lifting procedures and safety guidelines when using flat webbing slings AS 1353 to ensure a safe and successful lift. This includes selecting the appropriate sling for the load being lifted, inspecting the sling for any signs of damage or wear, and using proper lifting techniques and equipment.
• Store and handle webbing slings correctly.
• Inspect webbing slings and accessories before use and before placing into storage.
• Follow safe slinging practices, as given overleaf.
• Position the bight for choke lift at 120° (natural angle).
• Position the sling so that the load is uniformly spread over its width and protect the sling from sharp edges.
• Apply the correct mode factor for the slinging arrangement.
• Attempt to shorten, knot or tie webbing slings.
• Expose webbing slings to direct heat or flames.
• Use webbing slings at temperatures above 80°C or below 0°C without consulting the supplier.
• Expose webbing slings to chemicals without consulting the supplier.
• Shock load webbing slings.
• Use webbing slings which are cut or which have loose or damaged stitching.
• Use a sling with a missing/damaged label or illegible markings
Selecting the Correct Sling
Webbing slings are available in a range of materials and sizes in single leg and endless sling forms. Select the slings to be used and plan the lift taking the following into account:
Material - polyester identified by a blue label is resistant to moderate strength acids but is damaged by alkalis; polyamide (Nylon) identified by a green label is virtually immune to alkalis but is damaged by acids; and polypropylene identified by a brown label is little affected by acids or alkalis but is damaged by some solvents, tars and paints and therefore, suitable for appliances where the highest resistance to chemicals other then solvents is required.
Capacity - the sling must be both long enough and strong enough for the load and the slinging method.
Apply the mode factor for the slinging method.
For use at temperatures exceeding 80°C or below 0°C refer to the suppliers instructions.
For flat woven slings made to BS EN 1492-1:2000 + A1: 2008 *
Polyester And Polyamide -40ºC to 100º
Polypropylene -40ºC to 80ºC
Ranges vary in a chemical environment, in which case the advice of the manufacturer or supplier should be sought.
If the slings are used in multi-leg arrangement the angle formed between the legs should not be less than 30° or greater than 90°.
If abrasion, heat generated by friction or cutting from edges or corners are likely select a sling fitted with protective sleeves and/or use suitable packing.
Slings with grade 8 fittings and multi-leg slings with grade 8 master links should not be used in acidic conditions. Contact with acids or acidic fumes causes embrittlement to grade 8 materials. If exposure to chemicals is likely, the manufacturer or supplier should be consulted.
Storing and Handling Webbing Slings
Never return wet, damaged or contaminated slings to storage. They should be cleaned with clear water and dried naturally. Never force dry webbing slings.
Store webbing slings hung from non-rusting pegs which allow the free circulation of air.
The storage area should be dry, clean, free of any contaminates and shaded from direct sunlight.
Do not alter, modify or repair a webbing sling but refer such matters to a Competent Person.
NOTE: The material from which the sling is manufactured may be identified by the colour of the label or printing on the label: Polyester =Blue, Polyamide (Nylon) = Green, Polypropylene = Brown and the sling may also be dyed with a colour code to indicate SWL.
Using Webbing Slings Safely
Do not attempt lifting operations unless you understand the use of the equipment, the slinging procedures and the mode factors to be applied.
Do not use defective slings or accessories.
Check the correct engagement with fittings and appliances, ensure smooth radii are formed, do not twist or cross slings and do not overcrowd fittings.
Position the sling so that the load is uniformly spread over its width.
Position the bight for a choke lift at the natural (120°) angle to prevent friction being generated.
Ensure that stitching is in the standing part of the sling away from hooks and other fittings.
Take the load steadily and avoid shock loads.
Do not leave suspended loads unattended. In an emergency cordon off the area.
In-service Inspection and Maintenance
Maintenance requirements are minimal. Webbing slings may be cleaned with clear water. Remember weak chemical solutions will become increasingly stronger by evaporation.
Before each use inspect webbing slings and, in the event of the following defects, refer the sling to a Competent Person for thorough examination: illegible markings; damaged, chaffed or cut webbing; damaged or loose stitching; heat damage; burns; chemical damage; solar degradation; damaged or deformed end fittings.
