Polyester Round Slings for Industrial Rigging
Synthetic round slings are the preferred rigging solution for teams requiring high-capacity lifting without the abrasive weight of wire rope slings or chain slings. Available in vertical capacities from 2,600 lb to 100,000 lb, these synthetics slings utilize a "floating" core of polyester yarn that distributes the load pressure evenly across the lifting surface.
Manufactured from 100% high-tenacity polyester fibers, Holloway round slings resist UV degradation, rot, and mildew. The soft, seamless cover conforms to the shape of the load, making them the ideal choice for lifting machined parts, painted pipe, valves, and fragile structural components where metal slings would cause surface damage.
Key Benefits of Polyester Round Slings
Holloway Lifting Round Slings provide functional advantages that support safe and efficient industrial rigging.
Non-Marring Surface Contact
The soft, double-wall cover protects finished, painted, or polished surfaces from scratches and crushing damage.
High Strength-to-Weight Ratio
Significantly lighter than chain or wire rope of equal capacity, reducing rigger fatigue and back strain during setup.
Load Stability
The flexible body flattens against the load, increasing surface area grip and reducing slippage.
Low Stretch Characteristics
Polyester yarns offer approximately 3% elongation at rated capacity, providing better load control than nylon web slings.
Visual Safety Indicators
Color-coded jackets allow for instant capacity verification from a distance, while internal red core yarns provide a "Go/No-Go" inspection warning.
Rotatable Wear Points
The hook and load contact points can be rotated with every lift, significantly extending the service life of the sling.
Design & Engineering Considerations
Round slings perform best when paired with hardware that maximizes their efficiency. Proper selection of connection points is critical to prevent fiber damage.
- Connection Hardware : Pins and trunnions should have a sufficient diameter to prevent "crimping" the internal yarns.
- Edge Protection : While durable, polyester can be cut by sharp edges. Always use wear pads or corner guards when lifting loads with sharp 90-degree edges.
Environmental Awareness
- Temperature : use between -40°F and 194°F (-40°C to 90°C).
- Chemicals : Resistant to common acids and bleaching agents but can be degraded by concentrated alkalis (ethers/strong soaps).
- UV Exposure : Store away from direct sunlight to prevent long-term strength loss.
Round Sling Types
Holloway Houston manufactures the two primary round sling configurations used in global construction and oil & gas operations. Both are produced in-house with strict quality control.
Endless Round Slings (HHERS)
The most versatile configuration, featuring a continuous loop design.
Application : Ideal for vertical, choker, and basket hitches.
Advantage : Allows the user to rotate the sling, preventing repetitive stress on a single point of the cover.
Eye & Eye Round Slings (HHEER)
Designed with a protective sleeve that creates reinforced lifting eyes at both ends.
Application :
Best for connecting directly to shackles or crane hooks.
Advantage : Provides a distinct connection point with extra abrasion protection in the eye.
Holloway Houston’s round slings are not imported resells; they are manufactured in our Houston, Texas facility to make sure consistent quality and rapid availability.
High-Strength Load-Bearing Core
Each sling contains continuous loops of high-tenacity polyester yarn that carry 100% of the lifting load.
Protective Double-Wall Jacket
The core is enclosed in a seamless polyester cover that protects against abrasion and UV exposure without contributing to load strength.
Proof Tested and Fully Traceable
Every sling is proof tested to 200% of its vertical Working Load Limit and tagged with a unique serial number for complete manufacturing traceability.
Precision Length and Capacity Configuration
Slings are manufactured to exact length and Working Load Limit requirements, ensuring accurate fit, consistent performance, and compatibility with specific lift plans.
Inspection & Care Criteria
Per ASME B30.9 standards, round slings must be inspected before every lift.
Visual Inspection Indicators
- ASME B30.9 – Slings (Current Edition).
- OSHA lifting and rigging regulations for workplace safety and inspection practices.
- ISO 4878 — Textile slings — General safety requirements.
- EN 1492-2 — European standard for textile round slings made from man-made fibers.
Remove from service immediately if:
Red Core Yarns are Visible: This indicates the protective cover has been breached.
Missing Tag: Identification tag is illegible or missing.
Heat Damage: Evidence of melting, charring, or weld splatter.
Knots: The sling has been tied in a knot (this reduces capacity by up to 50%).
Chemical Damage: Fibers appear brittle, stiff, or discolored.
