Its outstanding reliability and environmental adaptability make it a core transmission component for heavy-duty port equipment.

Main technical characteristics:
Rated power range of 200–3000 kW, meeting the needs of cranes of different tonnages; input speed typically 750–1800 rpm, compatible with motor or diesel engine drive; output torque up to 500 kN·m or more, with strong heavy-load starting capability; Gear ratio range of 5–100, supporting multi-speed control; equipped with a forced circulation lubrication system, maintaining operating oil temperature between -20°C and 90°C; protection rating of IP65 or higher, offering excellent dust and water resistance; housing constructed from high-strength cast iron or welded steel structure, providing robust impact resistance; gear precision meeting ISO 6 grade or higher, ensuring smooth transmission; Equipped with temperature and vibration sensor interfaces, supporting intelligent monitoring; designed for a service life exceeding 100,000 hours, with a maintenance cycle of up to 5,000 hours. These parameters fully meet the high-intensity and high-reliability operational requirements of port cranes.

Main application areas:
Port crane gearboxes are primarily used in various port handling equipment, including container gantry cranes, portal cranes, and tyre-mounted gantry cranes, among other large-scale lifting machinery. At container terminals, it provides reliable power for the hoisting, trolley, and gantry travel mechanisms of gantry cranes; at bulk cargo terminals, it drives grab buckets, ship unloaders, and other equipment to handle bulk goods such as ore and coal; at general cargo terminals, it provides smooth speed control for portal cranes, floating cranes, and other equipment. Additionally, it is widely used in heavy-duty lifting equipment such as gantry cranes in shipyards and offshore platform cranes, as well as in the transmission systems of port mobile machinery like reach stackers and stackers. Its excellent impact resistance, corrosion resistance, and long service life make it perfectly suited for the harsh operating conditions of ports, including high-intensity continuous operations and high salt fog corrosion, making it a core transmission component in modern port logistics equipment.

Important Tips:
When using port crane gearboxes, strict adherence to operating procedures is mandatory. Overloading (instantaneous load exceeding 200% of the rated value) and frequent rapid starts and stops (starting intervals must exceed 3 minutes) are strictly prohibited. Regular maintenance is critical, including checking oil levels and quality every 500 hours using specified lubricants, cleaning the breather valve monthly to ensure proper ventilation, and inspecting and replacing aged seals quarterly. For professional maintenance, gear meshing conditions must be inspected every 2,000 hours, and annual vibration spectrum analysis must be conducted to predict bearing condition, with only original manufacturer parts permitted. For special operating conditions, the base must be reinforced before typhoon season, low-temperature lubricant rated for -30°C must be used in winter, and seals must be inspected immediately after water-related operations. Safety precautions: If oil temperature exceeds 90°C during operation, the unit must be shut down. Abnormal vibration (exceeding 7.1 mm/s) requires immediate diagnosis. Unauthorised modifications or welding repairs are strictly prohibited. It is recommended to establish a digital maintenance record system for predictive maintenance to ensure the gearbox achieves its designed service life of over 15 years in the harsh port environment.
