Double Link Chain Grade 80 (Components)
Product Overview
The hqlifting Grade 80 double chain sling is designed to offer superior load support and safety in lifting applications. Its double chain design provides stability and control during lifting operations. With chains ranging from 6 mm to 32 mm, these slings meet various industrial lifting needs.
Each double chain sling has a top master link that connects to a shortening hook for precise length adjustments. The lower end of the chain is equipped with self-locking shackle-type hooks for safe load handling. Our slings can be configured with up to four chain legs, providing additional connection points and greater control.

Each lifting chain is tested with twice the working load limit and receives a unique marking for full traceability.
