Gantry Crane Gearbox

The gantry crane gearbox powers lifting by reducing motor speed and increasing torque. Built from high-strength alloy steel, the gantry crane gearbox resists wear, handles frequent start-stop cycles, and performs reliably in ports, factories, shipyards, and construction sites. Its compact design saves space, while flexible installation ensures compatibility with different crane models. With stable power transfer and customized options, the gantry crane gearbox delivers efficiency, durability, and long service life.

Product Features and Applications

1.Strong torque output: Reduces speed, increases torque, and ensures stable lifting.

2.Durable structure: Alloy steel with quenching and tempering for long service life.

3.High adaptability: Customizable for different crane models and environments.

4.Low noise: Noise-absorbing housing keeps noise ≤ 85 dB.

5.Easy maintenance: Extended oil-change cycle lowers maintenance costs.

It’s used for container handling (rail-mounted/rubber-tired gantry cranes) in ports, heavy machinery/raw material movement in factories/warehouses, steel structure/prefab lifting in construction, and large ship section handling (heavy gantries) in shipbuilding.

Product Details

1.Gear Design: High-precision gears (Grade 5–6), ground for smooth meshing, reduce friction, and extend lifespan.

2.Cooling System: Natural cooling for light duty; forced cooling for heavy continuous duty, preventing overheating.

3.Installation Options: Supports foot-mounted and flange-mounted setups; customizable for special gantry crane requirements.

4.Oil System: Works with long-life gantry crane gearbox oil, minimizing oil change frequency.

5.Safety Protection: Strong housing with oil level indicators for easy inspection, ensuring safe operation.

Product Support

Hanko Heavy Industry has decades of experience in manufacturing crane components. Each gantry crane gearbox goes through raw material inspection, heat treatment, and precision machining. Before delivery, sampling inspections by batch are conducted, including ultrasonic testing, magnetic particle inspection, and a load test with no less than 1.1 times the rated load. We are manufacturers of gantry crane gearbox, offering both standard and customized solutions. Our ISO-certified factory, strict quality control, and professional engineering team guarantee safety, durability, and international compliance.

Swivel Crane Hooks

Swivel crane hooks allow loads to rotate freely, reducing wire rope stress and improving accuracy.

Single Crane Hook

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.

Overhead Crane Hook

The overhead crane hook is a vital lifting component for bridge cranes, gantry cranes, and other overhead lifting equipment.

Mobile Crane Hook

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.

Forged Crane Hook

A forged crane hook is a key lifting component that ensures both operator and load safety.

Eot Crane Hook

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.
