IntroductionGrade 100 QOSL Chain Sling is a four-leg lifting assembly manufactured from quenched and tempered Grade 100 alloy steel chain and components. The sling is fitted with a quad oblong master link assembly on the top and four Grade 100 self-locking safety hooks on the bottom, providing secure multi-point load attachment and enhanced lifting safety. Compared with Grade 80 slings, the Grade 100 design offers approximately 25% higher Working Load Limit for the same chain size. Each sling is permanently identified with a serial number, chain size, grade, exact sling length, and Working Load Limit to ensure complete product traceability.
Key Features- Quad-leg configuration for even load distribution and excellent load stability.
- Quad oblong master link assembly on top for multi-point attachment.
- Four Grade 100 self-locking (safety) hooks on the bottom to reduce risk of accidental disengagement.
- Manufactured from quenched and tempered Grade 100 alloy steel for higher WLL compared to Grade 80.
- Each sling permanently identified with individual serial number, chain size, grade, exact sling length and WLL for traceability.
- Proof tested, visually inspected and dimensionally verified prior to shipment.

Standards & Testing- Manufacturing Standards: Manufactured from quenched and tempered Grade 100 alloy steel chain and components in accordance with EN 818-2, EN 1677-1, EN 1677-3, EN 1677-4, ASME B30.9, OSHA 1910.184, AS 2321, and ISO 3077 requirements for Grade 100 lifting chain sling assemblies.
- Design Factor: Minimum design factor 4:1.
- Testing: Each sling is proof tested, visually inspected, dimensionally verified, and checked for component compatibility before shipment. The chain complies with EN 818 fatigue requirements and withstands 20,000 load cycles at 1.5 times the WLL.
- Supply: Every sling is supplied with an individual serial number, identification tag, written certification, and complete traceability records.
- Applications: Suitable for overhead lifting, multi-point lifting, heavy machinery handling, structural steel erection, offshore lifting, precast concrete installation, wind power projects, and industrial material handling.
- Maintenance: Inspect before each use for chain elongation, excessive wear, cracks, corrosion, self-locking hook operation, deformation, damaged master links or connecting links, and missing identification tags. Remove from service if defects exceed inspection criteria.
