HOW CHAIN SLINGS SHOULD BE STORED & MAINTAINED: EXPERT GUIDE

When it comes to lifting operations, chain slings are among the most durable and reliable lifting accessories available. But even the strongest Grade 80 or Grade 100 chain sling can quickly become unsafe if it’s poorly maintained or stored incorrectly.

Over the years, I’ve seen perfectly good chain slings fail inspections simply because they were left outside, tangled on workshop floors, or never properly checked between jobs. In many cases, the damage was avoidable. Good storage and maintenance practices not only improve safety but also extend the working life of lifting equipment and help businesses stay compliant with UK lifting regulations.

In this guide, I’ll walk through exactly how chain slings should be stored, maintained, inspected, and handled to keep them safe, compliant, and operational for as long as possible.

Why Proper Chain Sling Maintenance Matters

Chain slings operate under extreme loads and harsh working environments. Whether they’re used in construction, manufacturing, offshore lifting, or industrial rigging, they’re constantly exposed to:

Abrasion
Shock loading
Corrosion
Chemicals
Dirt and contamination
Moisture and weather exposure

Without regular maintenance, these factors can weaken the sling and significantly increase the risk of lifting failure.

Correct maintenance helps to:

Reduce workplace accidents
Meet LOLER and PUWER compliance requirements
Improve lifting safety
Reduce replacement costs
Increase equipment lifespan
Prevent failed inspections and downtime

If a sling shows signs of excessive wear or damage, it should be replaced immediately with a properly certified alternative from our chain slings collection.

How Chain Slings Should Be Stored

Storage is often overlooked, but it plays a major role in the longevity of lifting chains.

Store Chain Slings in a Clean, Dry Environment

Moisture is one of the biggest causes of corrosion and premature wear. Chain slings should always be stored indoors in a dry, well-ventilated area away from standing water or damp conditions.

Avoid storing chain slings:

Outside exposed to weather
Directly on concrete floors
In chemically contaminated areas
Near excessive heat sources
In corrosive atmospheres

Ideally, lifting chains should be kept on dedicated storage racks or hanging systems.

Hang Chain Slings Correctly

One of the best ways to store chain slings is by hanging them individually from purpose-built sling racks.

This helps prevent:

Tangling
Twisting
Impact damage
Uneven wear
Kinking

Chains left in piles or thrown into storage bins are far more likely to suffer damage to hooks, master links, and shortening clutches.

Proper hanging also makes inspection easier before use.

Separate Damaged or Quarantined Slings

Any sling awaiting inspection, repair, or disposal should be clearly separated from serviceable equipment.

A common best practice is using:

Red tags for defective slings
Quarantine areas
Lockable inspection cages

This prevents damaged lifting equipment accidentally being returned to service.

Avoid Chemical Exposure

Certain chemicals can seriously damage alloy chain slings. Acids, alkalis, and harsh industrial cleaning agents may weaken the material or accelerate corrosion.

If chain slings are used in chemical environments:

Clean them immediately after use
Inspect regularly for signs of corrosion or discolouration
Follow manufacturer guidance carefully

How Chain Slings Should Be Maintained

Good maintenance is about consistency. Small routine checks often prevent major failures later.

Carry Out Pre-Use Inspections

Before every lift, operators should visually inspect the chain sling for defects.

Key things to check include:

Chain Damage

Look for:

Cracks
Gouges
Bent links
Excessive wear
Stretching
Heat damage
Corrosion

Hook Condition

Inspect hooks for:

Bent tips
Cracks
Excessive throat opening
Missing safety catches

Identification Tags

The sling ID tag should always remain legible and securely attached. Missing tags can make the sling non-compliant because the working load limit (WLL) can no longer be verified.

Clean Chain Slings Regularly

Keeping chain slings clean makes inspections easier and reduces corrosion risks.

After use:

Remove dirt, grease, mud, or debris
Wipe down chains if exposed to moisture
Allow wet chains to fully dry before storage

Avoid aggressive cleaning methods that may damage the chain surface.

For heavily contaminated chains, use manufacturer-approved cleaning products only.

Lubricate When Necessary

Some chain sling assemblies benefit from light lubrication, particularly around moving components like shortening clutches or couplings.

However, avoid excessive lubrication because:

Dirt and grit can stick to oily surfaces
Inspections become more difficult

Always use lubricants recommended by the manufacturer.

Monitor Wear and Stretching

Over time, chain links naturally wear down through repeated use.

Excessive wear reduces the chain diameter and weakens lifting capacity.

As a rule:

Any reduction in chain diameter beyond manufacturer tolerance requires removal from service
Stretched chain links are a serious warning sign of overload

If you notice elongated links, the sling should be immediately quarantined and inspected by a competent person.

LOLER Inspection Requirements for Chain Slings

Under UK regulations, chain slings used for lifting operations must undergo regular thorough examinations.

Under LOLER:

Lifting accessories typically require inspection every 6 months
Inspections must be completed by a competent person
Records must be maintained

A thorough examination goes beyond a visual check and may include:

Wear measurements
Crack detection
Dimensional checks
Identification verification

Failure to maintain inspection records can lead to compliance issues and potential prosecution following an incident.

Common Chain Sling Mistakes to Avoid

Even experienced lifting teams sometimes develop poor habits over time.

Leaving Slings Outside: Rain, frost, UV exposure, and contamination all accelerate deterioration.
Dragging Chains Across Floors: Dragging chain slings across rough surfaces causes unnecessary wear and may damage links or hooks.
Using Damaged Slings “One More Time”: This is one of the biggest safety risks in lifting operations. If there’s any doubt about the condition of a chain sling, remove it from service immediately.
Ignoring Minor Damage: Small cracks, worn hooks, or distorted links rarely improve over time. Early intervention prevents bigger problems later.

When Chain Slings Should Be Removed from Service

Chain slings should be immediately removed from use if they show signs of:

Cracking
Severe corrosion
Heat damage
Bent or twisted links
Missing safety catches
Excessive wear
Chain stretch
Illegible ID tags
Weld repairs not approved by the manufacturer

Never attempt unauthorised repairs on lifting chains.

Only qualified specialists should repair or re-certify chain sling assemblies.

Best Practices for Extending Chain Sling Lifespan

If you want chain slings to last longer while staying compliant and safe, these practices make a huge difference:

Train staff properly
Store chains indoors
Inspect before every use
Follow LOLER schedules
Avoid shock loading
Keep chains clean and dry
Use edge protection where needed
Never exceed working load limits

Simple routines consistently outperform reactive maintenance.

Maintaining Chain Slings for Safety, Compliance, and Reliability

Chain slings are designed to handle demanding lifting tasks, but their safety and lifespan depend heavily on how they’re treated between lifts.

Proper storage prevents unnecessary deterioration. Regular inspections catch early signs of damage. Good maintenance habits improve reliability, support LOLER compliance, and reduce the risk of lifting incidents.

In my experience, businesses that take sling maintenance seriously not only create safer workplaces but also save considerable money over time through reduced equipment replacement and downtime.

When lifting operations are involved, prevention is always cheaper - and safer - than failure.
