At Hanko Heavy Industry, every overhead crane gearbox is engineered with precision. Gears are modeled and calculated to minimize cracking, stress, and wear. Each unit undergoes ultrasonic inspection, load testing, and dynamic balance verification. We are manufacturers of overhead crane gearbox, delivering standard models and customized designs. For overhead crane hoist gearbox, our products meet global requirements. Our team also provides modernization services, ensuring compliance with the latest standards.
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.
We offer custom manufacturing services for non-standard parts based on customer drawings or specific requirements.
Our products meet international standards and are exported worldwide, earning the trust of clients across Asia, the Middle East, Europe, and beyond.
