Portalkrangetriebe

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.

Produktmerkmale und Anwendungen

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.

Produktdetails

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.
