Crane Gearboxes
Hanko Crane Gearboxes - Your Reliable Crane Gearbox Manufacturer in China
The crane gearbox is a key power-transmission component used in overhead cranes, gantry cranes, and hoisting systems. It converts the motor’s high-speed rotation into low-speed, high-torque output, ensuring smooth, stable, and safe lifting operations. A gearbox typically includes hardened gears, shafts, bearings, and a durable housing designed to handle continuous heavy-duty work.
Hanko Heavy Industry manufactures high-strength crane gearboxes, overhead crane gearboxes, and gantry crane gearboxes through advanced gear cutting, heat treatment, and CNC machining. These processes deliver excellent torque capacity, low noise, and long service life. With compact designs and multiple reduction ratios available, Hanko crane reducers provide reliable performance for demanding lifting applications.
Different Types of Hanko Crane Gearboxes

Crane Gearmotor
Crane gearmotors are designed for lifting equipment, providing high torque, stable operation, shock resistance, and precise speed control under heavy load working conditions.
Reducer Motor
Reducer motors integrate a motor and speed reducer, ensuring efficient power transmission, reduced speed, increased torque, and long service life in demanding industrial environments.
Crane Reducer
Crane reducers are engineered to withstand heavy loads, frequent starts, and harsh conditions, delivering stable torque transmission, high efficiency, and extended operational reliability.
Motor Reducer
Motor reducers offer compact integration, smooth power delivery, optimized speed reduction, enhanced torque output, and dependable operation for continuous duty mechanical drive systems.
Hanko Heavy Industry Crane Gearbox Features
Crane Gearbox Features
- High Load Capacity for Heavy-Duty Lifting: Carburized and quenched gears in crane gearboxes deliver strong load-bearing performance, ensuring stable operation under heavy crane workloads.
- Compact Design for Easy Installation: With the same load capacity, these speed reducers offer a smaller footprint and lighter weight—ideal for cranes with limited installation space.
- Smooth Operation with Low Noise: Precision-ground gears in crane gearmotors improve transmission efficiency, reduce vibration, and minimize noise for a safer and more comfortable working environment.
- Long Oil Change Interval & Lower Maintenance Cost: Designed for extended lubrication cycles, helping reduce downtime and overall maintenance expenses while increasing crane gearbox lifespan.
Crane Gearbox Applications
Crane gearboxes are widely used in overhead cranes, gantry cranes, hoists, and material-handling systems to provide stable torque and precise speed control. They ensure safe and efficient lifting in steel mills, construction sites, ports, logistics centers, and manufacturing plants.
With high torque output and reliable performance, crane gear reducers are essential for heavy-duty operations, helping cranes handle continuous lifting, trolley travel, and long-term load positioning.
