40 Ton Heavy Duty Manual Marine Winch

Heavy Duty Manual Marine Winch for Barge Connection

Our heavy duty manual marine winch is purpose-built for barge connection, temporary mooring, and towing operations on inland waterways, workboats, and classical vessels.

Featuring a fully enclosed single-layer drum design, stainless steel anti-corrosion shaft system, and optional gravity handle, this marine manual winch delivers faster operation, reduced wear, and single-person control — even under maximum load up to 40 tons.

Perfect for traditional sailboats, mid-sized fishing boats & workboats, and remote sites lacking power infrastructure.

Key Design Advantages

🌀 Single-Layer Drum Design Prevents coil springing, debris accumulation, and uncontrolled tangling. Achieves up to 50% higher winding efficiency compared to conventional multi-layer or ratchet systems. Ideal as a manual winch single layer drum solution for consistent performance.

🔐 Double Pawl Structure + Built-in Spring Coil Enables simple, safe tensioning to maximum line pull with minimal effort. The integrated spring coil reduces rope “memory” damage and extends rope life — critical for frequent manual mooring winch applications.

🛠️ Stainless Steel Anti-Corrosion Shaft System Maintenance-free smooth operation — no additional lubrication required. Ensures long-term reliability in high-humidity, saline marine environments.

⚡ Optional Gravity Handle Dramatically increases make/break speed, reduces operator fatigue and component wear, while further improving overall safety during barge connection and disconnection.

🛡️ Fully Enclosed & Robust Construction Protects internal components from dirt and damage. Combined with marine-grade materials, this heavy duty manual winch is engineered for continuous heavy-duty use on barges and work vessels.

Application Scenarios

Barge fleets & inland towing — Secure and fast manual winch for barge connections without power dependency.

Temporary mooring & emergency tie-up — Reliable holding in remote or power-free locations.

Traditional sailboats & classic vessels — Functional upgrade that respects historical aesthetics.

Mid-size fishing boats & workboats — Effortless single-person operation for daily mooring tasks.
