AMC-30A-M2 Special Hydraulic Motor for Keeling Cranes On Ships

AMC-30A-M2 Special hydraulic motor for Keeling cranes on ships

 

 

Keeling cranes on ships are critical equipment for cargo loading and unloading at sea, requiring stable and precise power support to handle heavy loads in complex marine environments. The AMC-30A-M2 Special hydraulic motor for Keeling cranes on ships is engineered to meet these demands, serving as the driving force behind the crane's lifting, luffing, and slewing actions. As a Special hydraulic motor, it integrates high torque output and precise speed control, addressing the unique challenges of marine operations-such as salt spray corrosion, continuous vibration, and sudden load changes. The AMC-30A-M2 motor has been tested in actual shipboard operations, proving its reliability in ensuring smooth and efficient crane movements.​

 

 

The AMC-30A-M2 motor stands out in Keeling crane applications with its ability to deliver strong torque while maintaining stable operation. It can output a continuous torque of 3,500 N·m at 1500 rpm, easily handling the heavy lifting tasks of Keeling cranes (such as hoisting containers or bulk cargo). As a Keeling cranes on ships motor, it adopts a unique oil distribution structure that minimizes pressure fluctuations, ensuring the crane arm moves smoothly without jitter-critical for precise cargo positioning.​

Another key advantage of this Special hydraulic motor is its adaptability to marine environments. Its housing is made of marine-grade alloy steel with anti-corrosion treatment, passing 1,000-hour salt spray tests to resist rust and erosion from seawater. The Keeling cranes on ships motor also features a reinforced bearing design, which can withstand the continuous vibration caused by ship sway, reducing wear and extending service life to over 12,000 hours of operation.​

 

 

• High Torque & Efficient Power: The AMC-30A-M2 motor achieves 94% mechanical efficiency, converting hydraulic energy into mechanical power with minimal loss, ensuring the Keeling crane can lift heavy loads without excessive energy consumption.​
• Precise Speed Regulation: Equipped with a proportional control valve interface, this Special hydraulic motor supports stepless speed adjustment (50-1500 rpm), allowing the crane to switch between fast lifting and slow positioning flexibly.​
• Strong Overload Capacity: It can withstand 150% rated torque for short periods, handling sudden load increases when the crane lifts cargo from the sea surface (such as overcoming initial inertia).​
• Easy Maintenance: The Keeling cranes on ships motor adopts a modular design, enabling quick replacement of wearing parts (like seals and bearings) during shipboard maintenance, reducing downtime

The AMC-30A-M2 motor is specifically designed to power key actions of Keeling cranes:​

• Lifting Mechanism: As a Keeling cranes on ships motor, it drives the winch to lift or lower cargo, ensuring stable speed even when the load changes (e.g., from empty hook to full load).​
• Slewing Mechanism: The Special hydraulic motor provides smooth rotational power for the crane's slewing action, allowing precise positioning of the crane arm over the cargo hold or ship deck.​

In every operation, this motor proves to be an indispensable component for Keeling cranes, combining the specialized performance of a Special hydraulic motor with the reliability of the AMC-30A-M2 motor in marine environments.​
