Classification by Operation and Drive Method
Manual marine winch: With an extremely simple structure and no power source required, it offers convenient operation and low maintenance costs. Suitable for small vessels and auxiliary mooring/lifting tasks, it is a cost-effective choice for light-load, high-frequency scenarios.
Mechanical transmission winch: Features a heavy-duty gear transmission structure, offering strong load-bearing capacity and stable operation. It can be adapted for power drive, meeting the demands of heavy-duty operations such as lifting and mooring for large vessels.
Classified by application scenarios
Mooring winch: Specifically designed for ship berthing, it efficiently retracts and extends ropes to ensure stable mooring at ports and anchorages, suitable for various mooring operations of different vessels.
Cargo winch: Services for ship cargo loading and unloading, deck lifting, enabling efficient transfer and hoisting of onboard materials, suitable for cargo needs of ocean-going vessels, engineering ships, etc.
Classification by protective process
• Galvanized Corrosion-Resistant Type: The entire body undergoes hot-dip galvanization, offering exceptional resistance to salt spray and corrosion, making it perfectly suitable for high-humidity, high-salt marine environments and significantly extending the equipment's service life.
•Industrial Coating Protection Type: Professional marine-grade anti-corrosion coating, balancing protective performance with aesthetic texture, suitable for conventional maritime working environments, with fully optimized structural strength.
Classified by load capacity
Lightweight Series: Primarily manual models, flexible and lightweight, suitable for small vessels and auxiliary operations.
Heavy-duty series: Featuring mechanical transmission as the core, it delivers high load capacity and exceptional reliability, meeting the demands of large vessels and heavy engineering operations.
