Marine crane hook swivel

What Is a Marine Crane Hook Swivel?

A marine crane hook swivel is a rotating device that connects the crane’s hoist line to the lifting hook, allowing the load to rotate freely without twisting the wire rope. In marine applications, this feature is essential to prevent tangling and reduce stress on lifting components caused by wave motion, wind, or vessel movement.

Marine Crane Hook Swivel Product Features

• 1. High-Strength Steel Construction: The Weihua marine crane hook swivel is forged from high-grade alloy steel to ensure superior load-bearing capacity and resistance to deformation under heavy stress.

• 2. Corrosion Resistance: Designed for marine use, all surfaces are treated with anti-corrosion coatings or made of stainless materials to withstand harsh saltwater environments.

• 3. 360-Degree Rotation: The swivel mechanism allows for full 360° rotation, preventing the wire rope from twisting and ensuring smooth load alignment during lifting and lowering.

• 4. Heavy-Duty Hook with Safety Latch: Equipped with a robust crane hook safety latch to prevent accidental unhooking, ensuring safe and reliable operation.

• 5. Load-Tested & Certified: Every Weihua marine crane hook swivel is rigorously tested and certified in accordance with international maritime standards such as ABS, DNV, or CCS.
