Grade 100 Lifting Assemblies

Chain connectors & master links form critical connection points within compatible lifting-chain assemblies. Whether selecting a master link for a chain sling or replacing an approved connector assembly, the correct chain grade, nominal diameter, working load limit & connection geometry must be confirmed.

Industrial Shed's Chain Connectors & Links collection includes Grade 100 master links, multi-link assemblies & chain-connector configurations for Australian lifting, rigging, manufacturing & industrial maintenance applications.

Compare the available products by chain size, number of connector positions, internal link dimensions & manufacturer specifications.

Choose the Right Chain Connector or Link

• Master Links: Provide the upper connection point for a compatible lifting-chain assembly.

• Master Links With Two Connectors: Combine a master link with two specified connector positions.

• Multi-Link Assemblies: Provide multiple connection points for approved multi-leg chain sling arrangements.

• Four-Connector Assemblies: Suit specified four-leg configurations where approved by the manufacturer.

• Super-Large Master Links: Offer larger internal dimensions for compatible lifting connections.

• Grade 100 Connectors: Are designed for specified G100 lifting-chain systems.

The correct component depends on the complete assembly design, not the number of connectors alone.

Grade 100 Chain Connectors

Grade 100 (G100) lifting components are designed for compatible high-strength alloy chain assemblies.

The collection includes selected G100 master-link & connector configurations in different nominal chain sizes.

Before ordering, confirm the chain grade, diameter, connection geometry & the manufacturer's stated working load limit.

A G100 connector should not automatically be fitted to a G80 assembly or a different manufacturer's chain without documented compatibility.

Master Links for Lifting Chain Slings

A master link provides the upper connection point between a compatible lifting sling & an approved crane hook or lifting attachment.

Its internal dimensions must allow correct seating without crowding, tip loading or side loading.

Industrial Shed lists master-link assemblies with different internal sizes, including selected 110 × 60 mm, 260 × 140 mm & 430 × 220 mm configurations.

These dimensions are product-specific & must be checked against the intended hook & lifting arrangement.

A larger master link is not automatically suitable for a heavier load.

Two-Connector Master Link Assemblies

Two-connector master link assemblies provide specified connection points for compatible chain legs.

The collection includes selected G100 configurations for different chain diameters & master-link sizes.

When selecting a two-connector assembly, check:

• Chain Size: Must match the specified chain.

• Connector Compatibility: Must suit the approved chain & fitting system.

• Master-Link Dimensions: Must fit the intended lifting hook.

• Working Load Limit: Must be verified for the complete assembly.

• Sling Geometry: Must suit the planned lifting arrangement.

The number of connectors does not determine capacity by itself.

Four-Connector Multi-Link Assemblies

Multi-link assemblies with four connector positions are used in compatible multi-leg lifting arrangements.

Industrial Shed's collection includes selected G100 four-connector designs in different sizes.

A four-leg lifting arrangement requires assessment of sling angles, load distribution & the number of legs effectively carrying the load.

Never assume that adding more legs increases capacity in direct proportion.

Use the manufacturer's rating tables & competent lifting guidance.

Super-Large Master Links & Multi-Links

Some lifting arrangements require larger master-link openings to suit particular lifting hooks or connection geometries.

The collection includes super-large G100 master-link & multi-link assemblies with published internal dimensions.

Before selecting one, check the hook bowl, available clearance, loading direction & complete assembly rating.

Oversized links should not be chosen simply because they appear more robust.

Choosing the Correct Chain Size & Link Dimensions

Connector selection should begin with the original lifting assembly specifications.

Important details include:

• Chain Grade: G100 components must match the approved assembly requirements.

• Nominal Chain Diameter: Must suit the connector design.

• Internal Link Dimensions: Must accommodate the intended hook or attachment.

• Connector Count: Must suit the sling configuration.

• Working Load Limit: Must be appropriate for the complete lift.

• Identification & Traceability: Must satisfy applicable inspection requirements.

Chain Connectors vs General-Purpose Links

Rated lifting-chain connectors are different from general-purpose chain links, repair links or hardware connectors.

A general-purpose link may be suitable for specified utility applications, but it must not be substituted into a rated lifting assembly.

Similarly, a connector that physically fits the chain may still be unsuitable because of its grade, dimensions or design.

Chain Connector Inspection & Replacement

Lifting-chain connectors require inspection before use & periodic examination according to applicable requirements.

Check for cracking, deformation, excessive wear, corrosion, damaged connection points & missing identification.

Replacement components must match the approved assembly design.

Do not weld, machine, heat-treat or modify a lifting connector unless expressly authorised through an applicable approved process.

Safety & Care

• Verify chain grade, nominal diameter & connector compatibility before assembly.

• Check the working load limit of the complete lifting system.

• Inspect links & connectors for cracks, wear, distortion & corrosion.

• Confirm correct hook seating without side loading or tip loading.

• Assess sling angles & load distribution for multi-leg assemblies.

• Never mix unapproved components or improvise repairs.

• Remove damaged, unidentified or incorrectly fitting components from service.

Chain Connectors & Links FAQs

What Is a Grade 100 Chain Connector?

A G100 chain connector is designed for compatible Grade 100 lifting-chain systems. Its suitability depends on chain size, connection geometry & the complete assembly rating.

What Is the Difference Between a Master Link & a Multi-Link?

A master link provides an upper connection point, while a multi-link assembly includes additional connection elements for specified multi-leg arrangements.

Can I Use a G100 Connector With G80 Chain?

Only if the complete combination is specifically approved & rated for the intended application. Do not assume compatibility based on size or physical fit.

Does a Four-Connector Assembly Have a Higher Load Capacity?

Not necessarily. Capacity depends on the approved assembly, chain size, sling angle, load distribution & manufacturer rating.
