Chain sling Grade 100 QOF

4-pointsteelalloy

Introduction
Grade 100 QOF 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 foundry hooks on the bottom, providing a large hook opening for heavy-duty lifting applications. 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 (Q) chain sling configuration for balanced four-point lifting
• Quad oblong master link assembly (O) on top
• Grade 100 foundry hooks (F) on the bottom with large throat openings for oversized attachment points
• Manufactured from quenched and tempered Grade 100 alloy steel chain and components
• Approximately 25% higher WLL than Grade 80 for the same chain size
• Permanently identified with serial number, chain size, grade, exact sling length, and WLL for traceability

Standards & Quality
Manufactured in accordance with EN 818-2, EN 1677-1, EN 1677-2, EN 1677-4, ASME B30.9, OSHA 1910.184, AS 2321, and ISO 3077 requirements for Grade 100 lifting chain sling assemblies. Design factor: 4:1. 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. 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, foundry operations, precast concrete installation, offshore lifting, and industrial material handling operations.

Maintenance
Inspect before each use for chain elongation, excessive wear, cracks, corrosion, deformation of foundry hooks, damaged master links or connecting links, and missing identification tags. Remove the sling from service if defects exceed applicable inspection criteria.
