This news post focuses on our newly upgraded 15-ton fishing boat hydraulic winch (150kN rated pull), developed per official engineering drawings. We answer core buyer questions around its three key patented components: proportional electro-hydraulic valve, emergency manual handwheel, and automatic rope spooling device.
Q1: What advantages does the electric proportional valve bring to this 15T fishing winch?
A: The integrated electric proportional valve is the precision control heart of this marine winch, connected to Port A (hoisting) and Port B (lowering) hydraulic circuits.
1. Stepless speed regulation: It adjusts oil flow proportionally via electric signals, allowing fishermen to seamlessly shift from ultra-slow creeping speed for delicate net deployment to fast winding speed for full-load trawl recovery, rated at a maximum 40 m/min single-layer line speed.
2. Shock-free load handling: It eliminates sudden hydraulic surges, preventing sharp jerks that tear fishing nets or fatigue Φ18 steel wire ropes under the 150kN working pull force.
3. Stable performance at sea: Matched with the A2FE160 hydraulic motor and 35Mpa working pressure, it maintains consistent tension amid rough ocean waves, reducing equipment wear and improving crew safety.
4. Simple operation: Operators fine-tune hauling speed remotely without manual valve manipulation, greatly lowering labor intensity during long fishing shifts.
Q2: Why is the top-mounted handwheel an indispensable safety feature for marine fishing winches?
A: The horizontal handwheel assembly serves as a dual-purpose emergency and fine-tuning system, a mandatory safety design for offshore fishing vessels:
1. Power failure emergency backup: If the vessel’s main hydraulic power or electric proportional control malfunctions at open sea, crew rotate the handwheel to manually lift/lower heavy nets or catch. It avoids losing expensive fishing gear or creating dangerous deck load hazards when electrical systems break down.
2. Micro-adjustment for precise operation: When deploying nets near reefs, seabed obstacles or fish cages, the handwheel delivers ultra-fine incremental rope movement that electronic control cannot replicate. This drastically reduces snags, rope abrasion and net damage.
3. Direct valve manifold linkage: The handwheel mechanically connects to the main valve block, controlling both hoisting and lowering oil paths reliably without hydraulic power support.
Q3: How does the matched rope spooler (rope arranging device) extend winch & wire rope service life?
A: Designed to match the 793mm wide drum with a 500m Φ18 wire rope capacity, the automatic spooler solves the biggest pain point of ordinary fishing winches: messy rope winding.
1. Uniform layered winding: It guides steel wire to stack neatly across the Q355 drum, preventing overlapping, squeezing or rope piling under heavy 150kN tension. Uneven winding would quickly fray wire ropes and scratch the drum surface.
2. Full drum capacity utilization: Orderly rope arrangement maximizes the drum’s storage space, supporting the full 500m rope length as marked on the drawing, without sacrificing load capacity.
3. Maintenance cost reduction: Neat winding cuts wire rope replacement frequency by over 40% and lowers daily maintenance downtime for fishing fleets. It also stabilizes output torque (rated 41100 N·m) across all winding layers.
Q4: What other marine-grade technical specs support long-term offshore fishing use?
A: This 150kN fishing hydraulic winch is built to withstand harsh saltwater marine environments:
- Static brake torque reaches 1000 N·m, with 2–2.5 MPa brake release pressure to hold full loads stationary; an extra manual band brake adds secondary safety lock.
- Working temperature range: -20℃ ~ 70℃, compatible with 220# industrial gear oil for year-round global fishing waters.
- Compact integrated base dimensions optimized for limited fishing boat deck space; fully sealed valve blocks resist salt fog corrosion.
- Test load up to 125/150 kN dynamic/static for reliable heavy-duty trawling, longline fishing and aquaculture cage lifting.
Q5: Which fishing vessel customers is this 15-ton hydraulic winch suitable for?
A: It targets medium and large commercial offshore fishing boats, trawlers and aquaculture workboats. Vessel owners prioritizing precise control, emergency safety and low maintenance will benefit most from the triple design advantages of proportional electric control, manual handwheel backup and automatic rope spooling. It balances efficiency, safety and durability for unpredictable open-sea working conditions.
