Swivel crane hooks are forged from high-strength alloy steel, designed for swivel hook heavy duty lifting. With 360° smooth rotation, they prevent rope twisting and improve safety. Precision bearings ensure stability, while heat treatment and anti-corrosion coating extend service life. Certified and tested at 1.5× load, they cover wide crane hook capacity, making them reliable for ports, construction, mining, and steel plants.

Hanko Heavy Industry produces forged swivel crane hooks under strict quality control. Each hook is inspected with magnetic particle testing, ultrasonic checks, and overload verification. We are manufacturers of swivel crane hooks, which gives us full control from raw material to final product. Whether you need a swivel eye hook for light duty or a swivel hook heavy duty model for steel plants, Hanko ensures certified safety and durability.
Swivel crane hooks allow loads to rotate freely, reducing wire rope stress and improving accuracy.
The single crane hook is the most common lifting component in hoisting systems. Compared with double hooks, it provides a simple, cost-effective solution for medium loads.
The overhead crane hook is a vital lifting component for bridge cranes, gantry cranes, and other overhead lifting equipment.
A mobile crane hook is a vital component that connects the crane to the load. Designed for heavy-duty use, it ensures strength, safety, and efficiency.
A forged crane hook is a key lifting component that ensures both operator and load safety.
The eot crane hook connects crane and load, ensuring safety and efficiency during lifting. It works with hoist and trolley systems and supports crane main hook and auxiliary hook lifting.
Hanko products are manufactured using high-strength materials and go through strict quality inspections to ensure durability and operational safety.
