Custom Lifting Chain Sling
Product Overview
Our custom lifting chain sling is engineered for superior performance in demanding industrial lifting applications. Designed to meet the highest safety standards, these slings provide unmatched durability, flexibility, and load-bearing capacity. Whether you require single-leg, double-leg, or multi-leg configurations, our custom lifting chain slings are tailored to your specific needs, ensuring optimal safety and efficiency in every lift.
Manufactured from premium alloy steel chains, each custom lifting chain sling undergoes rigorous testing to comply with international regulations such as EN 818-4, ASME B30.9, and ISO 3076. Ideal for heavy-duty operations, these slings excel in environments where wire rope or synthetic slings fall short, offering exceptional resistance to abrasion, cutting, and high temperatures up to 400°C. With customizable lengths, fittings, and end terminations—including hooks, shackles, and master links—our slings adapt seamlessly to diverse rigging requirements.
From construction sites to manufacturing facilities, a custom lifting chain sling delivers reliable performance across global industries. Its compact design minimizes downtime during storage and transport, while color-coded tags provide instant identification of working load limits (WLL). Investing in our custom solutions means prioritizing worker safety, reducing operational risks, and enhancing productivity.

Note: WLL values are for new slings only. Actual capacities vary with sling angle and configuration. Custom sizes up to 32mm diameter available for WLL exceeding 50 tons.
Application Scenarios
A custom lifting chain sling is the go-to solution for high-risk, heavy-load lifting across multiple sectors. In construction, they securely hoist steel beams, precast concrete panels, and machinery components, thriving in rugged outdoor conditions. Shipyards rely on our slings for maneuvering massive anchors, propellers, and hull sections, where saltwater exposure demands corrosion-resistant builds.
Manufacturing plants use custom lifting chain slings for die handling, engine block transfers, and assembly line rigging, benefiting from their low stretch and precise control. In oil & gas, they lift valves, pipes, and subsea equipment under extreme pressures and temperatures. Mining operations deploy them for ore buckets and conveyor components, enduring abrasive materials without failure.
Other key scenarios include automotive production for lifting chassis and transmissions, power generation for turbine blades and generators, and warehousing for palletized heavy goods. Their versatility extends to entertainment rigging for stage equipment and military logistics for armored vehicle components. No matter the scenario, our custom lifting chain sling ensures compliance with OSHA, EU Machinery Directive, and other global standards.
Advantages
Choosing our custom lifting chain sling offers distinct edges over standard slings. First, unparalleled customization allows exact matching to load shapes and weights, minimizing stress points and extending lifespan. Unlike nylon or polyester slings, chain slings resist cuts, chemicals, and UV degradation, reducing replacement frequency by up to 40%.
Grade 100 options provide 25% higher WLL than Grade 80 equivalents at the same size, optimizing payload without added bulk. Rigorous manufacturing processes—including automated welding and non-destructive testing—eliminate defects, backed by a 7:1 safety factor. Lightweight yet robust, they enhance crane efficiency and operator mobility.
Environmental adaptability shines: operational in temperatures from -40°C to 400°C, with optional coatings for acidic or marine settings. Compliance documentation and RFID tracking ensure audit-ready traceability, simplifying inspections and insurance claims.
