Heavy Duty Trawl Block for Commercial Fishing Net Hauling Systems

Purpose-Built Trawl Block for High-Load Fishing Net Towing Systems  

The trawl block is engineered specifically for commercial trawl operations where consistent tension control and smooth net towing are critical. 

It supports heavy fishing nets and trawl doors under dynamic offshore loads, making it an essential component in marine trawl pulley block systems and fishing deck rigging. 

Designed for stability and efficiency, this block enhances operational safety while improving net handling performance in demanding fishing environments.  

The rated working load is 2-30tons] under single-line configuration.

Precision Sheave Groove for Trawl Wire and Synthetic Ropes  

The sheave groove is optimized to accommodate both wire rope and high-strength synthetic lines used in modern trawl systems. 

This reduces rope wear, improves line tracking, and maintains stable hauling speed during continuous fishing cycles. 

Such performance is essential in marine trawl block applications where rope longevity and operational efficiency directly impact vessel productivity.  

Suitable for rope diameters 16–88mm.  

Send us your rope details to ensure precise groove matching.

Reinforced Frame Structure for Offshore Dynamic Loads  

The trawl block frame is fabricated from heavy-duty steel plates designed to withstand shock loading, vibration, and constant movement at sea. 

Reinforced load-bearing areas ensure structural integrity during trawl net deployment and retrieval, making it dependable for offshore fishing pulley systems and marine rigging hardware.  

Side plate thickness is 110-198mm with reinforced stress points.

Corrosion Protection Designed for Saltwater Environments  

Operating in harsh marine conditions requires superior surface protection. 

The trawl block is treated with corrosion-resistant coatings to withstand salt spray, humidity, and prolonged exposure to seawater, ensuring durability in marine pulley block and fishing deck equipment applications.  

Available surface treatments include [hot-dip galvanizing / marine epoxy paint / powder coating.  

Let us know your environment to recommend the optimal protection.

Versatile Connection Options for Fishing Vessel Rigging  

The block can be equipped with eye, hook, or shackle attachments to suit different trawl rigging layouts and vessel deck configurations. 

This flexibility allows seamless integration with winches, booms, and net handling systems used in commercial fishing operations.  

Connection type is eye.  

Provide your rigging layout so we can match the correct connection design.

Engineered for Continuous Commercial Fishing Duty Cycles  

Unlike general-purpose pulley blocks, the trawl block is designed for high-frequency, long-duration operation typical in trawl fishing. 

Its heavy-duty sheave system, reinforced body, and marine-grade corrosion protection ensure dependable performance during repeated net deployment and recovery.
