Click:222 Edit: Chuanghe HoistingTime:2026-09-29 11:22:41

Heavy lifting operations require reliable lifting accessories that can handle demanding working conditions.

Whether lifting steel structures, machinery, construction materials, industrial components or heavy equipment, the chain connecting the load to the crane or hoist is an important part of the overall lifting system.

One widely used category of lifting chain is the G80 Lifting Chain, also known as Grade 80 Alloy Steel Chain.

G80 chain is manufactured from high-strength alloy steel and is designed specifically for lifting applications. It is commonly used in chain slings, lifting assemblies and other industrial material-handling applications.

Compared with ordinary general-purpose chains, lifting chains are manufactured and selected according to requirements related to strength, durability, dimensions and working load limits.

For industrial buyers, understanding the characteristics of G80 chain is important when selecting lifting accessories for cranes, hoists and rigging systems.

G80 Lifting Chain

What Is G80 Lifting Chain?

G80 lifting chain is a high-strength alloy steel chain designed for lifting and load-handling applications.

The term G80 refers to the chain's grade classification and its minimum breaking strength relative to its nominal size.

G80 chains are commonly manufactured from alloy steel and heat treated to achieve the mechanical properties required for lifting applications.

Typical uses include:

l Chain slings

l Heavy machinery lifting

l Steel structure handling

l Construction lifting

l Industrial rigging

l Cargo securing applications where specifically permitted

 

l Crane and hoist lifting systems

A G80 chain should not be confused with ordinary hardware chain.

A chain used for lifting suspended loads must be appropriately rated and selected for the intended application.

Why Is G80 Chain Used for Lifting?

The primary reason G80 chain is widely used in lifting applications is its combination of:

Strength + Durability + Flexibility + Wear Resistance

Chain has an important advantage over some other lifting accessories because it can be configured in different ways.

For example, a chain sling can be configured as:

l Single-leg sling

l Two-leg sling

l Three-leg sling

l Four-leg sling

The configuration depends on the load and the lifting arrangement.

G80 Chain Construction

A typical G80 lifting chain consists of interconnected alloy steel links.

Each link is manufactured to specific dimensional and mechanical requirements.

The manufacturing process can include:

· Alloy steel material preparation

· Chain link forming

· Welding

· Heat treatment

· Calibration

· Surface treatment

· Dimensional inspection

· Mechanical testing

· Final inspection

Heat treatment is particularly important because the chain needs to achieve a suitable balance between strength and toughness.

Main Features of G80 Lifting Chain

1. High Strength

G80 alloy steel chain is designed to withstand significant tensile forces.

This makes it suitable for heavy industrial lifting when correctly selected.

The actual working load limit depends on:

l Chain diameter

l Chain configuration

l Sling angle

l Hitch type

l Load conditions

l Manufacturer specifications

2. Durable Alloy Steel Construction

G80 chains are commonly produced from alloy steel.

This provides the mechanical properties required for heavy lifting applications.

Proper material selection is especially important because lifting chains may be exposed to repeated loading and demanding industrial environments.

3. Flexible Configuration

Chain is flexible compared with rigid lifting components.

It can be configured into different sling arrangements and can adapt to various load shapes.

This flexibility makes chain slings popular in:

l Steel fabrication

l Construction

l Shipyards

l Machinery installation

l Industrial maintenance

4. Good Wear Resistance

Lifting chains can experience contact with:

l Steel surfaces

l Hooks

l Shackles

l Load edges

l Other chain links

A properly manufactured and maintained G80 chain can provide good resistance to normal industrial wear.

However, excessive wear can reduce the chain's safe working capacity and must be monitored.

G80 Lifting Chain Applications

Steel Fabrication

Steel fabrication companies frequently move heavy plates, beams and structures.

G80 chain slings can be used as part of lifting systems for suitable loads

Construction

Construction projects often require the lifting of:

l Steel beams

l Machinery

l Pipes

l Structural components

l Construction materials

G80 chain is commonly used in rigging systems for these applications.

Machinery Installation

Heavy machinery may need to be moved into factories or positioned during installation.

Chain slings provide flexible connection options for suitable lifting points.

Shipbuilding

Shipyards handle large steel structures and components.

Heavy-duty chain slings can form part of the rigging equipment used for appropriate lifting operations.

Industrial Maintenance

During equipment maintenance, machinery components may need to be removed, repositioned or installed.

G80 chain can be used with compatible hooks and lifting equipment when the application is properly assessed.

G80 Chain and Chain Slings

A G80 chain is often used as the basic chain component of a chain sling.

A typical chain sling assembly may include:

l G80 chain

l Master link

l Clevis sling hook

l Connecting link

l Shortening hook

Safety latch

The components must be compatible and appropriately rated.

A chain sling's capacity is determined by more than the chain diameter alone.

The complete assembly must be considered.

Common G80 Chain Diameters

G80 lifting chains are available in different diameters.

Common sizes can include:

l 6 mm

l 8 mm

l 10 mm

l 13 mm

l 16 mm

l 20 mm

l 22 mm

l 26 mm

l 32 mm

Actual available sizes vary according to the manufacturer and standard.

Larger diameter does not automatically mean that the chain is suitable for every lifting application.

The correct chain should be selected according to the required working load limit and configuration.

Understanding Working Load Limit

One of the most important concepts in lifting equipment is the Working Load Limit, commonly abbreviated as WLL.

WLL is the maximum load that the equipment is designed to lift under specified conditions.

For example, the WLL of a chain sling can be affected by:

l Chain diameter

l Number of legs

l Sling angle

l Hitch configuration

l Load distribution

l Hook type

l Connecting components

Therefore, buyers should never select a chain solely based on diameter.

Sling Angle and G80 Chain Capacity

When using multi-leg chain slings, sling angle becomes particularly important.

As the angle changes, the tension in each sling leg can change.

For example, a two-leg sling operating at a relatively small angle from the horizontal can experience greater tension than the same sling operating closer to vertical.

Therefore, the lifting plan should take sling geometry into account.

A qualified lifting professional should determine the appropriate configuration for critical lifting operations.

G80 Chain vs. G70 Chain

G80 and G70 chains are different grades designed for different applications.

How to Choose the Right G80 Lifting Chain

1. Determine the Maximum Load

Start by identifying the heaviest load that needs to be lifted.

For example:

2 tons → 5 tons → 10 tons → 20 tons

The chain and complete sling assembly must have an appropriate WLL for the actual lifting configuration.

2. Select the Correct Chain Diameter

Chain diameter affects the lifting capacity.

However, the diameter should be selected based on the complete manufacturer's rating rather than an assumption that a particular diameter always has the same capacity.

3. Determine the Sling Configuration

Decide whether the application requires:

l Single-leg sling

l Two-leg sling

l Three-leg sling

l Four-leg sling

The configuration affects load distribution and capacity.

4. Consider the Sling Angle

For multi-leg slings, calculate the expected sling angle.

Avoid assuming that increasing the number of sling legs automatically increases lifting capacity.

Load distribution may not be equal between all legs.

5. Select Compatible Fittings

Hooks, master links, connecting links and other fittings must be compatible with the chain.

All components should have suitable ratings.

G80 Chain Safety

Safety is one of the most important considerations when using lifting chains.

Never Exceed the Working Load Limit

The WLL must not be exceeded.

Overloading can result in permanent deformation or failure.

Inspect Before Every Use

Check the chain for:

l Cracks

l Excessive wear

l Bent links

l Elongation

l Corrosion

l Twisting

l Damaged welds

l Deformation

Any chain showing unacceptable damage should be removed from service.

Avoid Shock Loading

Sudden loading can generate forces significantly greater than the static weight of the load.

Operators should avoid:

l Jerking

l Sudden acceleration

l Sudden braking

l Dropping loads onto the chain

Protect the Chain From Sharp Edges

Sharp load edges can damage or deform chain links.

Appropriate edge protection and lifting techniques should be used where necessary.

Do Not Knot the Chain

Chains should not be tied into knots to shorten or modify them.

Use appropriate shortening hooks or approved chain components.

G80 Chain Inspection

Regular inspection is an important part of lifting equipment management.

A basic visual inspection should check for:

Wear

Look for excessive reduction in link diameter.

Elongation

Abnormally stretched links may indicate overloading or damage.

Corrosion

Severe corrosion can reduce the effective strength of the chain.

Deformation

Bent or twisted links should be evaluated before further use.

Cracks

Any visible cracks are serious defects.

Weld Condition

Welded areas should be inspected for visible damage.

For critical lifting operations, inspection should follow applicable local regulations, standards and competent-person procedures.

G80 Chain Maintenance

Proper maintenance can extend service life.

After use:

l Clean excessive dirt

l Inspect the chain

l Remove contaminants where appropriate

l Store in a dry environment

l Prevent unnecessary exposure to corrosive substances

Lubrication requirements depend on the chain design, manufacturer instructions and operating environment.

Storage of G80 Lifting Chain

Proper storage is often overlooked.

Chains should ideally be stored:

l In a dry location

l Away from corrosive chemicals

l Away from excessive moisture

l Protected from unnecessary impact

l Properly organized to avoid deformation

Do not leave lifting chains lying in areas where forklifts, vehicles or heavy machinery can run over them.
