Lifting slings are among the most versatile and widely used tools in material handling. Whether you're lifting a delicate machine part, a concrete pipe, or a steel beam, the right sling can make the job safer, faster, and more efficient.

In this comprehensive guide, we'll cover everything you need to know about lifting slings: types, capacity ratings, color coding, inspection, and safe usage practices.

What is a Lifting Sling?

A lifting sling is a flexible device used to attach a load to a lifting hook or crane. Unlike chains or wire ropes, slings are soft and conform to the shape of the load, distributing pressure evenly and avoiding damage to the lifted object.

Types of Lifting Slings

1. Round Slings

Round slings are endless-loop slings made from high-tenacity polyester fibers encased in a protective tubular cover. They are the most popular type of sling for general lifting because of their flexibility, strength, and load-protective properties.

• Infinite adjustment: Can be wrapped around any shape
• Flexible: Conforms to irregularly shaped loads
• Non-marring: Will not scratch or damage painted or polished surfaces
• Lightweight: Easy to carry and position

2. Webbing Slings

Webbing slings are flat-woven polyester straps with sewn eyes at each end. They offer better stability for certain loads and are commonly used in construction and heavy rigging.

• Stable load control: Wide flat surface prevents load rotation
• Easy inspection: Flat surface makes wear visible
• Standard lengths: Available in fixed lengths with eye ends

International Color Coding System

Lifting slings follow a standardized color code based on capacity (EN 1492). This allows operators to instantly identify the safe working load:

Color	Capacity (kg)	Common Uses
🟡 Purple	1,000	Light machinery, tools
🟩 Green	2,000	Motors, pumps, equipment
🟨 Yellow	3,000	Steel beams, heavy parts
🟦 Blue	5,000	Industrial machinery
🟧 Orange	8,000	Heavy construction
🟡 Red	10,000	Large structures, concrete

Sling Configuration & Capacity Reduction

The way you rig a sling affects its effective capacity. Always check the capacity chart for different configurations:

• Vertical (Straight): 100% of rated capacity —the maximum load for a single sling leg
• Choker: ~75% of rated capacity —the load is choked around the object
• Basket (90°): 200% of rated capacity —the sling passes under the load and both ends attach to the hook
• Basket (60°): 170% of rated capacity —angle reduces effective capacity
• Basket (45°): 140% of rated capacity — lower angle = lower capacity

Inspection & Retirement Criteria

Lifting slings must be inspected before each use. Remove from service immediately if you see:

• Cut or torn core yarns (visible through the cover)
• Frays, cuts, or worn areas on the webbing
• Heat or chemical damage (melted, glazed, or hardened areas)
• Missing or illegible capacity tag
• Knots or kinks in the sling body
• Broken or deformed fittings (eyes, rings, hooks)

Storage & Care

• Store slings in a cool, dry place away from direct sunlight
• Hang slings on racks — do not pile them on the floor
• Avoid contact with acids, alkalis, and harsh chemicals
• Clean with mild soap and water; dry before storing
