Australian & New Zealand AS 4497 standard round slings requires traceable label on
each polyester round sling. However,some times we are also required to provide
normal label to dcrease the cost.
Wristrong strongly advise the customers to use the traceable label on the round slings
to totally comply with the AS 4497 standard. Bellow we just example out the two kind
of labels we've ever produced before. Of course, Wristrong could produce other forma
label to meet the customers' unique design requirements.

Wristrong Heavy duty round sli​ng used in Herrenknecht Tunnelling Systems:

Endless round sling is an all-purpose lifting sling, which is both high strong and non-damaging to its load.
Extremely light in weight and infinitely flexible in all directions, it is easy and quick to manipulate even
when awkwardly shaped or fragile loads are being lifted.


The features of endless  round sling

1. Color-coded to international standard for indentification of lifting capacity

2. With special thickness jacket and sleeves  extend working life.

3. Each black strip is equal to 1ton capacity, it is easy to differentiate sling capacity.

4.WLL and length is clearly printed  on surface of sling.

5.Bearing point can be roated for longer working lift

6. The lifting capacity will not be affected if the core load bearing loops are not damaged

7. 100% polyester has less than 3% extension at rated capacity, and will return originally length, and 9-12% extension at break.

8.Clearly tag with serial number and a copy of certificate together with one sling.

9. Working temperature range: -40 -100 .


When using round slings always:

• Store and handle roundslings correctly.

• Inspect roundslings 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).

• Apply correct mode factor for the slinging arrangement.

• Use protection (to avoid cutting, friction etc) and fittings which allow the sling to form smooth radii.


When using round slings never:

• Attempt to shorten, knot or tie roundslings.

• Expose roundslings to direct heat or flames.

• Use roundslings at temperatures above 80°C or below 0°C without consulting the supplier.

• Expose roundslings to chemicals without consulting the supplier.

• Shock load roundslings.

• Use roundslings with cut or damaged outer covers.


Selecting the Correct Sling

Roundslings are available in a range of materials and sizes in endless sling form. 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;
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 to be 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 which may damage the sling are likely, select a 
sling fitted with additional protective sleeves and/or
use suitable  packing. Storing and Handling Roundslings Never 
return wet, damaged or contaminated slings
to storage.  They should be cleaned with clear water and dried naturally. 
Never force dry roundslings.


Store roundslings by hanging on 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
roundsling but 
refer such matters to a Competent Person. NOTE: The material from which the roundsling is
manufactured may be 
identified by the colour of the label or printing on the label: Polyester = Blue, Polyamide
(Nylon) = Green, 
Polypropylene = Brown. The outer sleeve of the sling will also be colour coded to indicate the
SWL in straight pull.


Using Roundslings 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 for correct engagement with fittings and appliances, ensuring smooth radii are formed which allow the

sling to assume its naturally flattened form under load. Do not overcrowd fittings.

• Position the bight for a choke lift at the natural (120°) angle to prevent friction being generated.

• Keep labels away from hooks and 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. Roundslings may be cleaned with clear water. Remember weak

chemical solutions will become increasingly stronger by evaporation Regularly inspect roundslings and, in
the event of the following defects, refer the sling to a Competent Person for thorough examination: illegible

markings; damaged or cut outer cover; damaged stitching; exposed inner core; heat damage; burns;
chemical damage
