What Is a Lifting Chain? A Technical Guide for Industrial Use

Lifting chains are essential components in material handling and rigging operations. Constructed from high-strength alloy steel, these chains are engineered to hoist, secure, and maneuver heavy loads under demanding industrial conditions. Their strength, durability, and adaptability make them indispensable tools across construction, manufacturing, marine, and logistics sectors.

Key Takeaways

• Lifting chains are assemblies made from alloy steel links, designed to handle heavy loads safely.
• They are crucial in industries requiring reliable load handling in extreme environments.
• Chain slings must comply with OSHA 1910.184 and ASME B30.9 standards.
• Proper selection, inspection, and maintenance ensure safety and longevity.
• Different chain grades (Grade 80, 100, 120) determine load capacity and application.

Understanding Lifting Chains

Lifting chains are used in conjunction with lifting slings, hoists, cranes, and other rigging equipment to raise or secure loads. What sets lifting chains apart from alternatives like wire rope or synthetic slings is their ability to withstand harsh conditions, including high temperatures, sharp edges, and corrosive environments.

Advantages Over Other Lifting Devices

• Cut and abrasion resistance: Superior to synthetic options.
• Temperature resilience: Performs well in heat-intensive environments.
• Adjustability: Chain length can be modified via attachments.
• Durability: Longer service life with proper care.

Chain Grades and Standards

Lifting chains are categorized by grades, which indicate their tensile strength and working load limits (WLL). These grades must align with industry standards to ensure safe operation.

Always check that lifting chains meet ASME B30.9 and OSHA 1910.184 requirements before use.

Components of a Lifting Chain Assembly

• Master Links: Primary connection point to the hoist or crane hook.
• Chain Legs: The load-bearing alloy steel links.
• Hooks: Typically grab, sling, or foundry hooks to attach to the load.
• Adjusters or Shorteners: Allow length modification for uneven loads.

Selecting the Right Lifting Chain

Key Selection Criteria:

• Load Weight and Type: Calculate total weight and distribution.
• Environmental Conditions: Consider exposure to chemicals, heat, or moisture.
• Frequency of Use: High-cycle operations may benefit from higher grades.
• Chain Configuration: Choose between single, double, triple, or quadruple leg slings.

We recommend using a qualified rigging expert to determine the appropriate WLL and configuration.

Inspection and Maintenance Best Practices

Daily Visual Checks

• Look for signs of wear, elongation, cracks, or corrosion.
• Ensure components are not deformed or damaged.

Periodic Inspections

• Conducted by a qualified person at regular intervals (at least annually).
• Chains showing excessive wear (typically more than 10% link diameter reduction) must be removed from service.

Maintenance Tips

• Clean chains to remove debris and corrosives.
• Lubricate to prevent rust and reduce friction.
• Store in a dry, temperature-controlled environment.

Evolution of Lifting Chains

Historically, lifting tools were bulky, prone to failure, and lacked standardized testing. The introduction of heat-treated alloy steel and rigorous standards like ASME B30.9 has transformed lifting chains into high-performance tools, improving safety and productivity across industries.

Conclusion

Lifting chains are not just tools; they are critical safety components in industrial rigging. Their proper use, selection, and upkeep can drastically improve operational efficiency and workplace safety.

FAQ

What standards should lifting chains meet?
OSHA 1910.184 and ASME B30.9 are the primary regulatory standards for lifting chain slings.

What’s the difference between Grade 80, 100, and 120 chains?
Each higher grade offers increased strength and working load capacity. Grade 120 is the strongest.

How often should chains be inspected?
Visually before each use and thoroughly by a qualified inspector at least annually.

Can chain slings be used in high-heat environments?
Yes. Lifting chains, especially Grades 100 and 120, perform well in elevated temperatures.

How do I determine the right chain for my task?
Assess load weight, environment, frequency of use, and number of sling legs required. Contact Bishop Lifting for expert guidance.
