Chain sling Grade 100 DOSL

2-pointsteelalloy

Description
Grade 100 DOSL Chain Sling is a double-leg lifting assembly manufactured from quenched and tempered Grade 100 alloy steel chain and components. The sling is fitted with a Grade 100 oblong master link on the top and two Grade 100 self-locking hooks on the bottom, providing secure two-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.

Introduction
Grade 100 DOSL Chain Sling is suitable for heavy-duty lifting applications requiring secure two-point load attachment and enhanced operational safety. The self-locking hooks automatically close and lock when the load is engaged, reducing the risk of accidental disengagement. The double-leg configuration distributes lifting forces evenly between two lifting points for improved load stability.
