Quick answer

What is an oblong ring?

An oblong ring, often called a master link, is an elongated steel ring used at the top of a sling assembly. It gathers one or more sling legs and sits on the crane hook, giving a single, well-shaped connection point for the lift.

Key takeaways

  • Acts as the top link connecting sling legs to the hook.
  • Inside dimensions must fit the crane hook and sling fittings.
  • Number of legs and sling angle affect the rating needed.
  • Rated, marked and documented for lifting use.

How Oblong Rings Work in Practice

In a multi-leg chain or wire-rope sling, every leg terminates at the master link. Its oblong shape seats properly in the hook bowl while leaving room for the leg connections, so the load is shared as designed.

Specify the inside length and width so the ring fits the crane hook, the section diameter, and the number of legs and required working load limit. For four-leg assemblies, a master link assembly with intermediate sub-links is often used.

Common Oblong Ring Forms

01

Single master link

For single- and two-leg sling assemblies.

02

Master link assembly

Master link with two sub-links for three- and four-leg slings.

03

Pear-shaped link

Narrower at one end to help keep fittings positioned.

04

Welded or forged construction

Production route confirmed against the rating requirement.

How to Choose the Right Oblong Ring

01

Working Load Limit

The master link must be rated for the full assembly load, including the effect of leg angles.

02

Hook Fit

Inside dimensions must allow the ring to seat freely in the hook bowl without binding.

03

Sling Angle

Wider leg angles increase force in each leg; state the intended angle range.

04

Assembly Compatibility

The ring must suit the connectors on each leg; share the sling details.

Safety note

Lifting and load-bearing products must be selected against a confirmed working load limit, the applicable standard and the actual rigging arrangement. Never use a part beyond its marked or documented rating, and inspect before every use.
