Lifting chain
Lifting Chain
Product Overview
Our lifting chain is engineered for superior performance in demanding industrial lifting operations. Crafted from premium alloy steel, these chains meet international standards such as EN 818-2, Grade 80, ensuring exceptional strength, durability, and safety. Designed for overhead lifting, towing, and rigging applications, our lifting chains provide reliable load handling capacities up to 50 tons or more, depending on configuration.
Each link in our lifting chain undergoes rigorous heat treatment processes, including quenching and tempering, to achieve high tensile strength and resistance to wear. Available in various diameters from 6mm to 34mm, these chains are ideal for use with chain hoists, cranes, and other lifting equipment. We prioritize precision manufacturing to minimize elongation under load, guaranteeing consistent performance even in harsh environments like marine, construction, and manufacturing sites.
Compliance with ISO 3077 and ASME B30.9 standards underscores the reliability of our lifting chain products. Whether you're securing heavy machinery, transporting cargo, or performing maintenance lifts, our lifting chains deliver unmatched safety and efficiency, reducing downtime and operational risks.

Application Scenarios
In construction and infrastructure projects, our lifting chain excels in hoisting steel beams, precast concrete elements, and heavy formwork. Its robust design ensures safe vertical and horizontal lifts on towering cranes, minimizing risks in high-altitude operations.
Within manufacturing facilities, lifting chains are integral to assembly lines for moving engines, transformers, and machinery components. Paired with electric chain hoists, they facilitate precise positioning, boosting productivity while adhering to OSHA safety protocols.
Shipping and logistics sectors rely on our lifting chains for container handling, cargo securing, and port crane operations. The corrosion-resistant finishes make them perfect for marine environments, where exposure to saltwater demands unyielding performance.
In mining and oil & gas extraction, these chains handle abrasive materials and extreme conditions, supporting dragline buckets, drilling rigs, and personnel lifts with proven reliability under dynamic loads.
Other uses include theater rigging, automotive production, and warehouse automation, where the lifting chain's versatility supports diverse rigging configurations for optimal efficiency.

FAQ
What is the difference between Grade 80 and Grade 100 lifting chain?
Grade 80 lifting chain offers a working load limit with a 4:1 safety factor, suitable for most industrial uses. Grade 100 provides higher strength (up to 25% more WLL) for specialized heavy-duty applications, both fully compliant with EN 818 standards.
How often should a lifting chain be inspected?
Visual inspections are recommended before each use and thoroughly every 6-12 months, or after exposure to shock loads. Follow ASME B30.9 guidelines, retiring chains showing wear over 10% or cracks.
Are your lifting chains suitable for overhead lifting?
Yes, our Grade 80 and higher lifting chains are specifically designed and certified for overhead lifting when used with compatible components and proper rigging techniques.
What finishes are available for corrosion protection?
Options include black oxide, galvanized (zinc-plated), and stainless steel variants, tailored to environmental demands from indoor dry settings to offshore marine exposure.
Can lifting chains be repaired if damaged?
No, damaged links must be replaced entirely. Welding repairs compromise strength; always use factory-welded assemblies for safety.
What is the maximum temperature for lifting chain operation?
Standard alloy steel lifting chains perform up to +200°C short-term; consult us for high-temperature alloys exceeding this limit.
