Chain sling 80 DOG

2-pointsteelsteel alloy

Product Overview
Grade 80 DOG Chain Sling is a double-leg lifting assembly manufactured from quenched and tempered Grade 80 alloy steel chain and components. The sling is fitted with a Grade 80 oblong master link on the top and Grade 80 grab hooks on the bottom, allowing quick chain length adjustment and balanced two-point lifting for overhead applications. Each sling is permanently identified with a serial number, chain size, grade, exact sling length, and Working Load Limit (WLL) to ensure complete product traceability.

• Testing Standards: Minimum design factor 4:1. Each sling is proof tested, visually inspected, dimensionally verified, and checked for component compatibility. Chain complies with EN 818 fatigue requirements and withstands 20,000 cycles at 1.5 times the WLL. Every sling is supplied with an individual serial number, identification tag, written certification, and full traceability records.
• Application Standards: Suitable for overhead lifting, two-point lifting, heavy machinery handling, structural steel erection, equipment installation, construction projects, mining maintenance, and industrial material handling.
• Maintenance: Inspect before each use for chain elongation, wear, cracks, corrosion, grab hook wear or deformation, damaged master links or connecting links, and missing identification tags. Remove from service if defects exceed inspection criteria.
