Marine Hydraulic Slewing Motor
The IHI HVN Series Hydraulic Slewing Motors are specially engineered for crane rotation applications in marine and offshore environments. These motors are responsible for rotating the crane structure smoothly and accurately during cargo handling operations. The HVN family has earned an excellent reputation for durability, smooth rotational control, and dependable performance aboard commercial vessels worldwide.
The HVN series is commonly found on bulk carriers, container ships, offshore support vessels, multipurpose vessels, and heavy-lift ships where accurate crane positioning is essential. Their rugged construction enables continuous operation under demanding marine conditions while maintaining excellent efficiency and reliability.
The IHI HVN Series is a hydraulic vane motor family designed specifically for slewing applications. The motor converts hydraulic pressure into rotational movement, allowing the crane to rotate safely and smoothly while handling cargo or equipment.
Unlike hoisting motors that lift loads vertically, slewing motors focus on controlled horizontal rotation. This makes them a critical component of any hydraulic deck crane system.
The HVN Series includes several configurations developed to suit different crane capacities and operational requirements:
The standard HVN motor is widely installed on conventional marine deck cranes and cargo handling systems.
The HVN-SS model provides improved stability and smooth rotation characteristics for continuous-duty operations.
Designed for enhanced rotational precision and positioning control.
A heavy-duty version developed for larger crane installations requiring greater torque output.
An advanced configuration commonly found on specialized offshore lifting systems and high-capacity marine cranes.
These features have made the HVN family one of the most trusted slewing motor solutions used in marine crane systems throughout the world.
The IHI HVN Series Hydraulic Motor typically consists of:
Each component is engineered to withstand the harsh operating conditions encountered in marine and offshore environments.
HVN motors are extensively used in marine deck cranes where smooth and accurate crane rotation is essential.
Cargo vessels rely on HVN motors to position loads safely during loading and unloading operations.
Offshore support vessels frequently use HVN-D and HVN-A motors due to their robust construction and dependable performance.
The HVN family is also installed in specialized hydraulic rotating machinery and deck handling systems.
