Gear couplings are precision-engineered mechanical devices that transmit torque between two shafts while compensating for misalignment. They provide high torque capacity, durability, and smooth power transmission. With compact design and strong gear teeth engagement, gear couplings reduce vibration and protect connected equipment. They are widely used in cranes, heavy machinery, and industrial drives. Simple maintenance and long service life make them a cost-effective choice.

1.High transmission efficiency:
The gear couplings can effectively transmit power to the drive wheel to ensure the normal operation of the mechanical equipment.
2.Compact structure:
The gear couplings are small in size, light in weight, take up less space, and are easy to install and maintain.
3.Wear resistance:
The gear couplings are made of wear-resistant materials and can maintain high wear resistance during long-term operation.
4.High reliability:
The gear couplings have high working reliability and stability, and can meet various harsh working environment requirements.
Gear couplings transmit torque between crane motors, gearboxes and shafts (hoist/travel mechanisms), accommodate misalignment, and ensure reliable power transfer for stable heavy-load lifting in overhead, gantry or swivel cranes.
1.Gear Coupling Hub: Precisely machined hub ensures secure shaft fit.
2.Gear Teeth: Hardened gear tooth couplings provide wear resistance.
3.Flexible Element: Allows angular and parallel misalignment.
4.Protective Coating: Anti-rust coating extends service life.
5.Assembly Parts: Easy-to-maintain gear coupling parts reduce downtime.
Hanko Heavy Industry focuses on the design and manufacturing of crane couplings, including high-performance gear couplings. Every unit is made from forged alloy steel, tested for torque capacity, and inspected with ultrasonic testing and dynamic balance. We strictly follow ISO and DIN standards. We are manufacturers of Gear couplings, offering both standard models and customized solutions. Our catalogue also includes gear motor couplings, and geared variable speed couplings to support different industries.
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.
