Grade 80 Swivel Self Locking Hook with Bearing SSB type

No.502007

The Grade 80 Swivel Self-Locking Hook with Bearing (SSB Type) is an advanced lifting component that combines a secure locking mechanism with a precision ball bearing. It is specifically designed to rotate smoothly even while under full load, preventing dangerous chain twist and ensuring optimal load alignment.

  • Rotation Under Load: Equipped with an integrated ball bearing that allows the hook to freely and smoothly swivel while fully loaded, significantly reducing torque on the rigging assembly.
  • Automatic Locking: Features a heavy-duty safety latch that automatically closes and firmly locks when tension is applied, preventing accidental load release during operations.
  • High-Strength Material: Forged from premium quenched and tempered Grade 80 alloy steel in strict compliance with EN 1677 standards for overhead lifting components.
  • Certified Safety & Durability: Rigorously proof-load tested to 2.5 times the Working Load Limit (WLL) with a 4:1 safety factor, and finished with a durable, corrosion-resistant powder coating.

Product Features

  • Ball Bearing Swivel: Equipped with a sealed ball bearing mechanism. Allows for smooth, continuous rotation under full load, making it essential for wire rope cranes to prevent rope damage.
  • Self-Locking Safety: Features an automatic locking mechanism. The hook closes and locks immediately when lifted, ensuring the load cannot slip out during operation.
  • Load Positioning: Allows the operator to easily rotate and position heavy loads while they are suspended, improving safety and precision during placement.
  • Heavy Duty Build: Forged from Grade 80 Alloy Steel with a fully enclosed swivel housing to keep grease in and dirt out. Compliant with EN 1677-3.
