Round Slings
What Is A Round Sling
A round sling, also called an endless round sling, is a flexible lifting sling used to safely lift and move heavy loads using cranes, hoists and other lifting equipment. It is typically made from high-strength polyester or nylon fibres encased in a durable tubular cover. The internal yarn carries the load while the outer cover protects the sling from wear and abrasion.
Unlike chain or wire rope slings, polyester round slings provide a soft, flexible lifting surface that adapts to the shape of the load, helping reduce damage to both the sling and the item being lifted.
Key Features Of Round Slings
- Excellent strength-to-weight ratio
- Suitable for vertical, choker and basket lifts
- Flexible design that rotates 360° around loads
- Gentle, non-abrasive lifting surface
- Lightweight and easy to handle
Applications For Endless Slings
-
Round slings are used across many industries, including:
- Construction: lifting beams, concrete and building materials
- Manufacturing: moving machinery and heavy components
- Marine & Shipping: loading cargo and containers
- Aviation: handling delicate aircraft parts
- Oil & Gas: lifting pipes and drilling equipment
Why Choose Polyester Round Slings?
- Lightweight and easy to transport and store
- Flexible design wraps easily around loads
- Colour-coded capacities for quick identification
- Non-conductive and safer around electrical hazards
- Protective outer sleeve guards against UV, moisture and abrasion
FAQs
How are round slings measured?
Round slings are measured by their effective working length (EWL). This is the usable length of the sling when it’s laid flat and ready to lift. Because they’re endless (looped), you measure the full loop and divide by two. Always choose a length that allows the load to be lifted safely without stretching or forcing the sling into tight angles.
How should endless round slings be stored when not in use?
Slings must be stored in a dry, clean area away from direct sunlight, chemicals, extreme temperatures, and mechanical damage to preserve their performance and prevent premature deterioration.
What signs indicate that an endless round sling should be removed from service?
A sling should be withdrawn from use if it shows cuts, abrasions, chemical damage, heat degradation, exposed internal fibres, or an illegible identification label.
How often should endless round slings be inspected?
Endless round slings must undergo a visual inspection before each use and a thorough examination at least every six months by a competent person, or more frequently depending on the severity of use or environment.
