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 Round 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 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
