Home / Adjustable Chain Slings

Adjustable Chain Slings

Our range of adjustable chain slings are available in 1-leg, 2-leg, and 4-leg variations, safely catering for loads of up to 47,900lbs.

Each adjustable chain sling comes equipped with a high-quality engineered grab hook that is fitted to the top Masterlink or Sublinks (dependent on leg quantity selected) via chain connector links providing users with easy adjustment of each chain length.

Simply drop the desired chain link into the grab hook to shorten an individual leg to suit your requirements – perfect for multi-purpose lifting of loads where the centre of gravity is offset.

Added Options With Adjustable Chain Slings

As with all Hackett chain slings, lengths of up to 30ft are available to purchase online, with all assemblies and components capable of withstanding the rigours of operating temperatures from 40°C/F to +200°c  (392°F) – quality and versatility rolled into one!

Every component has been individually tested to 2.5 times the stated safe working load limit, and once assembled in Texas, your fully complaint chain sling assembly has once again been tested to 2 times the working load limit.

Adjustable Chain Slings for Total Lifting Flexibility

When the job demands precision, adjustable chain slings give you unmatched versatility in the field. Built with quality Grade 80 or Grade 100 alloy chain, each sling is engineered for strength, safety, and on-the-fly length adjustment. Whether you're lifting irregular loads or working in confined spaces, our adjustable chain slings help you lift smarter—every time.

What Is an Adjustable Chain Sling?

Unlike fixed-length slings, adjustable chain slings use grab hooks or shortening clutches that allow operators to modify leg lengths to suit different lift scenarios. This makes them ideal for lifting uneven or unbalanced loads and reduces the need to stock multiple sling lengths.

Available Configurations

  • 🔩 1-leg to 4-leg assemblies
  • ⚙️ Shortening clutches or grab hooks for adjustability
  • 🔗 Grade 80 or 100 chain, assembled & tested in the USA using imported components
  • 🧪 Proof-tested & tagged to OSHA and ASME B30.9 standards
