Grade 80 Clevis Sling Hook with Ridge CSR Type

No.502039

The Grade 80 Clevis Sling Hook with Ridge (CSR Type) is a high-strength, premium lifting hook engineered for secure load attachment in demanding industrial and construction material-handling operations.

  • Enhanced Safety Design: Features a specialized protective ridge built directly into the hook body that shields the safety latch, significantly reducing the risk of accidental unhooking during complex lifts.
  • Direct Clevis Connection: Designed with a precision clevis pin attachment that allows for fast, secure, and direct integration into Grade 80 chain sling assemblies without the need for additional coupling links.
  • Heavy-Duty Construction: Forged from expertly quenched and tempered Grade 80 alloy steel, providing exceptional durability, wear resistance, and long-term reliability in harsh operating environments.
  • Certified Performance: Rigorously proof-load tested to meet strict international lifting standards, ensuring a robust 4:1 safety factor for confident, heavy-duty load management.

Grade 80 Clevis Sling Hook with Protective Ridge

*Ridge protects safety latch from ground impact

Product Features

  • Protective Ridge: Engineered with a raised ridge on the hook body. When dragged across floors (a common practice), this ridge hits the ground first, shielding the latch mechanism from crushing or shearing.
  • Clevis Connection: Features an integral clevis pin that connects directly to the chain link. This eliminates the need for a separate Hammerlock (Connecting Link), reducing weight and cost.
  • Heavy Duty Latch: Equipped with a strong, spring-loaded safety latch to ensure the load remains securely captured, even during slack conditions.
  • Standard Compliance: Forged from high-strength Grade 80 Alloy Steel (Quenched & Tempered) in accordance with EN 1677-2.
Design Advantage: The "Ridge" & Clevis
Feature Real-World Benefit
Protective Ridge Latch Durability. Shields the latch from damage when the hook is dragged or dropped. Result: The safety latch lasts significantly longer.
Clevis Pin Cost & Weight Saving. Connects directly to the chain. Result: Eliminates the need for a separate Hammerlock.
