4-Leg or Quadruple Leg Chain Sling

• Alloy chain slings are designed for overhead lifting and offer unmatched durability. They provide excellent performance in harsh environments. Grade 80(T) Chain is manufactured from heat treated alloy steel, and is ideal for heavy duty lifting applications.
• Available in lengths up to 8 metres and adjustable by means of grab hooks, our grade 80 chain slings are supplied with either clevis self-locking hooks or clevis sling hook as terminal fittings, alternaative fittings are also available.
• Extreme care should be taken when using the Grade 80 Chain Slings in close proximity of high temperature.
• Alloy Grade 80 slings should not be used in acidic or lyes solutions nor in any other corrosive environment.
• The assemblies include a load plate
• Finish: Powder coated
• Safety Factor: 4:1
• Standard: EN 818-4
• The last two numbers of the product code refer to the chain size, when ordering, e.g. a 4-leg assembly with a 10mm chain and a safety hook, the product code is 503001410. If you want to include cradle eye grab hooks in the assembly, the product code is 503002410.

A 4-leg chain sling is a type of lifting sling commonly used in industrial and construction settings to lift and transport heavy loads. It consists of four individual chains that are attached to a master link or a central ring at the top. The other ends of the chains are fitted with hooks or other attachments to secure the load.

The primary advantage of a 4-leg chain sling is its ability to distribute the load evenly across four points, as opposed to just two points in a 2-leg sling. This even distribution helps to reduce stress on each individual chain and on the load being lifted. As a result, 4-leg chain slings are well-suited for lifting irregularly shaped or sensitive loads, as well as loads that are prone to tilting or spinning during lifting.

A four leg sling comprises four legs permanently connected at their upper ends by a suitable link assembly and marked as an assembly. Four leg slings are mainly used to handle square or rectangular (four cornered) loads.

The key characteristics that make a 4-leg chain sling different from other types of slings are:

• Number of Legs: As the name suggests, a 4-leg chain sling has four individual chains, whereas other slings might have two or even more legs.
• Load Distribution: The four-leg configuration allows for better load distribution, providing increased stability during lifting operations. This feature makes it particularly useful for lifting large, unwieldy, or unevenly balanced loads.
• Versatility: 4-leg chain slings are versatile and can be used in various lifting scenarios. They can accommodate different hitch configurations and adapt to a range of load sizes and shapes.
• Strength and Durability: Chain slings are typically made of high-strength alloy steel, making them robust and capable of handling heavy loads in harsh environments.
