The advantage of textile slings slings compared with other designs and, above all, chain slings and steel wire are:
1. Less weight, in the same capacity. Textile slings much lighter metal. This property is particularly noticeable when working with heavy-duty straps. It is easier to produce movement of the sling under the load easier to start, it's easier to cling to the crane hooks. In this kind of textile slings have no equal. With large-slings can handle one man while the similar lines for the metal it takes a team. In addition, textile slings allow you to save not only human resources but also time spent loading and unloading.
2. Can be used in dealing with sensitive cargo. Goods (especially with soft edges or carefully prepared surfaces) less damaged by the rise. It is this property - the best characterization of textile slings. Metal straps have a small cross-section. Therefore, belt slings for lifting lumber, particle board, metal products made of them cut into the product lines and spoil their appearance. It is also not applicable metal slings and lifting products, with carefully prepared surface (yachts, boats, etc.), as it is left on grooves and notches. Textile slings are much better able to cope with this task, they carefully skirted the goods and do not spoil it, because have considerable flexibility.
3. Safety. In the textile slings are no metal protruding hairs (as in the slings of wire rope), which can lead to injury. Therefore, the use of textile sling helps to solve a very important issue - the safety of workers. As a consequence - the savings for payment of temporary disability and reduce downtime in the workplace.
4. Compactness. Textile slings easy to fold and store. Typically, the metal straps are woven into the storage bulky knot. Metal straps are also impossible to turn gently, as they have resilient properties, they are very difficult to move from place to place. All these shortcomings textile slings are deprived. They can roll up as you like, do they straighten and intertwine with each other. Textile slings take up little space and transportation. They can curl up under the compact size and extended to occupy any vacant niches. These lines can easily be placed, for example, in the cab and always have on hand. Additional space for textile slings just do not want to.
5. The low price of textile slings. It is also not a little important. Compared with the straps of metal, textile slings is much cheaper.

CAUTIONS:
- Do not attempt to use sling above rated lifting capacity.
- When selecting a sling,it is very important to consider the angles at which the sling will be used.
- Slings are subject to cutting when ifting items with sharp egeds.In this case,always use protective sleeves
- Do not use a damaged sling,and se only if trained.
- Do not tie knots in sling webbing as strength is greatly reduced.
- Never drag a sling beneth from a load which is resting on it.
- Chemical active environments can affect the strength of slings
- Inspect slings weekly or more frequently depending on the sling use conditions.
- Always strore slings in a cool,dry and dark place to extend the working lift.
- Always read and understand the operating instructions before use.
- Failure to comply with this warning may result in serious load damageand death or injury.
When using flat woven webbing slings always:
• Store and handle belt slings correctly.
• Inspect belt 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.
When using flat woven webbing slings never:
• Attempt to shorten, knot or tie belt slings.
• Expose belt slings to direct heat or flames.
• Use belt slings at temperatures above 80°C or below 0°C without consulting the supplier.
• Expose belt slings to chemicals without consulting the supplier.
• Shock load belt slings.
• Use belt slings which are cut or which have loose or damaged stitching
Selecting the Correct Sling
Belt 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 is resistant to moderate strength acids but is damaged by alkalis; polyamide (Nylon) is virtually immune to
alkalis but is damaged by acids; and polypropylene is little affected by acids or alkalis but is damaged by some
solvents, tars and paints.
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. 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.
Storing and Handling Belt Slings
Never return wet, damaged or contaminated slings to storage. They should be cleaned with clear water and dried
naturally. Never force dry belt slings. Store belt 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 belt 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 Belt 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, Maintenance and Replacement
Inspect slings each day before use, looking for:
Do not use worn or damaged slings or attachments. Discard or repair them. Use damaged slings only after they are repaired, reconditioned, and proof tested by the sling manufacturer or a qualified person. Keep certificates of proof test.
Maintenance requirements are minimal. Belt slings may be cleaned with clear water. Remember weak chemical
solutions will become increasingly stronger by evaporation. Regularly inspect belt 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.
