Grade 100 Chain Sling
Product Overview
The grade 100 chain sling represents the pinnacle of heavy-duty lifting solutions, engineered for the most demanding industrial applications. Fabricated from premium high-tensile alloy steel, our grade 100 chain slings achieve a minimum tensile strength of 1000 N/mm², offering up to 25% greater working load limits (WLL) compared to grade 80 equivalents. This superior strength-to-weight ratio makes them ideal for lifting and rigging operations where safety, reliability, and efficiency are non-negotiable.
Each grade 100 chain sling is meticulously heat-treated and proof-tested to exceed international standards such as EN 818-4, ASME B30.9, and ISO 3076. Available in configurations including single-leg, double-leg, triple-leg, and quadruple-leg assemblies, these slings feature quenched and tempered components for exceptional fatigue resistance and impact toughness. Color-coded blue for easy identification, our grade 100 chain slings ensure compliance and quick visual inspection on job sites worldwide.
Designed for versatility, the grade 100 chain sling supports a broad range of capacities from 1.4 tons for smaller diameters up to over 50 tons in multi-leg setups. Whether you're handling machinery, construction materials, or offshore cargo, this sling delivers unmatched performance while minimizing downtime and replacement costs.

Application Scenarios
The grade 100 chain sling excels in high-stakes environments requiring maximum lifting capacity. In construction and infrastructure, it handles precast concrete elements, steel beams, and bridge components with precision and safety. For manufacturing and heavy machinery, these slings are perfect for transporting engines, transformers, and assembly line equipment, where space constraints demand compact, high-strength rigging.
In the oil and gas sector, grade 100 chain slings support offshore platform maintenance, pipe handling, and rig moves, enduring corrosive marine atmospheres and extreme loads. Mining operations benefit from their abrasion resistance when lifting ore skips, rock drills, and conveyor sections in harsh underground conditions. Additionally, shipbuilding and port logistics rely on them for container securing, crane lifts, and heavy cargo transfers, optimizing throughput while adhering to stringent safety protocols.
Versatile enough for renewable energy projects, such as wind turbine blade installation and solar panel array assembly, the grade 100 chain sling ensures reliable performance across diverse global industries.
Advantages
Opting for a grade 100 chain sling delivers tangible benefits over lower grades. Its enhanced tensile strength allows for reduced chain diameters, slashing weight by up to 20% and enabling use with smaller cranes—directly lowering fuel costs and emissions. The advanced metallurgy provides superior shock load absorption, reducing link deformation and failure risk during sudden stops or impacts.
Longevity is a hallmark: grade 100 chain slings exhibit double the fatigue life of grade 80, minimizing inspections and replacements. Compliance with global standards like DGUV, OSHA, and Australian AS 3775 ensures seamless integration into certified operations. Economically, the higher upfront investment yields ROI through decreased downtime and maintenance, with each sling backed by a unique serial number for full traceability.
Environmental resilience includes options for low-temperature (-40°C) and high-temperature (up to 200°C) applications, broadening usability without compromising integrity.

FAQ
What is the difference between grade 100 and grade 80 chain slings?
Grade 100 chain slings offer 25% higher WLL for the same diameter due to superior alloy composition and tensile strength (1000 N/mm² vs. 800 N/mm²), providing greater safety margins and efficiency.
How do I properly inspect a grade 100 chain sling?
Conduct daily visual checks for nicks, gouges, or stretch exceeding 5% of original length. Measure links for wear (max 10% reduction) and verify tags for WLL. Professional inspections every 6-12 months per ASME B30.9.
Can grade 100 chain slings be used in wet or corrosive environments?
Yes, with optional galvanized or stainless steel finishes. Avoid chemical exposure; rinse with fresh water post-use and store in dry conditions to prevent hydrogen embrittlement.
What is the safe working angle for multi-leg grade 100 chain slings?
Optimal at 60° included angle (120° between legs). Derate WLL by 1.73 factor at 60°; consult charts for precise calculations to avoid overload.
Are custom lengths and configurations available for grade 100 chain slings?
Absolutely. We manufacture to your specifications, from 1m to 20m legs, with matching grade 100 components, ensuring balanced load distribution.
What certifications accompany your grade 100 chain slings?
Each sling includes a test certificate confirming 2.5x proof load, material traceability, and compliance with EN 818-4, ASME B30.9, and relevant regional standards.
