Grade 80 Swivel Sling Hook

Grade 80 Steel EN 1677 Compliant Overhead Lifting

⚠️ CRITICAL WARNING INFORMATION

This hook is a positioning device and is not intended to rotate under load. For a swivel sling hook designed to rotate under load, please refer to our Grade 80 Swivel Sling Hook with ball bearing.

Product Overview

The Grade 80 Swivel Sling Hook is a forged alloy steel rigging component engineered for heavy-duty overhead lifting applications. Manufactured from high-tensile Grade 80 steel and finished with a durable yellow powder coating, it is designed to work seamlessly with Grade 80 chain slings or wire rope assemblies fitted with a swivel eye connection.

Key Features

  • Free-rotating 360-degree swivel eye for effortless load alignment and positioning before lifting begins.
  • Spring-loaded latch (visible in the polished steel tongue) that automatically secures once the load is applied, preventing accidental disengagement.
  • Drop-forged, quenched and tempered alloy steel construction for a superior strength-to-weight ratio.
  • Individually proof-load tested and magnetic-particle (magnaflux) crack inspected after heat treatment to ensure structural integrity.
  • Compliant with EN 1677 performance requirements, with a standard safety factor of 4:1.
  • Bright yellow painted finish for high visibility on the job site and corrosion resistance.

Applications and Uses

This swivel hook is widely used in construction, ports, shipyards, mining, and heavy manufacturing wherever chain slings or wire rope slings need a reliable, rotatable connection point to a crane hook or lifting fixture. The self-locking latch design makes it especially suited for overhead lifting where operator safety and load security are critical, such as steel coil handling, precast concrete lifting, and machinery rigging.

Engineering & Quality Assurance

  • Material: Quenched and Tempered Alloy Steel.
  • Proof Load: Tested at 2.5 times WLL with certification for each batch manufactured.
  • Fatigue Rated: Tested for over 20,000 load cycles to ensure long-term durability.
  • Inspection: Magnaflux crack detection is performed 100% on each batch.
