INSTRUCTIONS & CAUTIONS
Check the Working Load Limit
Before using your trawl block, always verify its working load limit (WLL). Ensure that the block is rated to handle the load it will bear during your operation. Using the block beyond its WLL can lead to failure, damage to equipment, and potential accidents. If you’re ever unsure about the limits, refer to the product specifications or consult a professional.
Regular Inspection and Maintenance
Inspect your trawl block regularly, especially before and after each use. Look for wear, cracks, or corrosion on key parts like the sheave, swivel eye, and bearings. Keep all moving parts clean and lubricated to ensure smooth operation. Regular maintenance helps extend the lifespan of your equipment and reduces the risk of unexpected breakdowns in the middle of a job.
Avoid Sudden Impact or Shock Loads
Try to avoid shock loading when using the trawl block. Sudden, jerky movements can stress the block beyond its capacity and cause damage over time. Always ensure a smooth and steady load is applied to avoid unnecessary strain. Operating your block with a consistent load prevents early wear and helps keep your gear in top condition.
Protect from Corrosion
Corrosion is a major concern, especially in marine environments. After each use, rinse the trawl block with freshwater to remove salt and debris. For long-term protection, store the block in a dry area, away from extreme weather conditions. Consider using a corrosion-resistant coating or check if your block is galvanized for added protection against saltwater exposure.

OUR REVIEWS
FAQ
How should I maintain trawl blocks?
-
Regular Inspections:
Inspect your trawl blocks regularly for signs of wear, corrosion, or damage. Ensure that all components are in good working order before each use. -
Clean After Use:
After each operation, clean your blocks to remove saltwater and any debris that might have accumulated. This prevents corrosion and extends the lifespan of the block. -
Lubricate Moving Parts:
Use marine-grade grease to lubricate the moving parts, especially bearings and sheaves. This reduces friction and improves the efficiency of the block. -
Check Bearings and Sheaves:
If exposed to harsh conditions, pay extra attention to the bearings and sheaves. Look for any signs of wear or damage and replace parts as needed to ensure smooth operation.
How do I choose the right trawl block for my operation?
When selecting a trawl block, consider the working load limit (WLL), the type of operation (e.g., commercial fishing, offshore mooring), and the environment (e.g., saltwater exposure). Ensure the block is made from high-strength materials and has the necessary corrosion resistance for your specific application. If in doubt, consult our team for expert advice on the best block for your needs.
What should I do if my trawl block is damaged?
If your trawl block shows signs of significant wear, such as cracks or a damaged sheave, it’s important to replace it immediately to prevent further issues. Don’t use a damaged block, as it can cause equipment failure or accidents. Contact us for replacement parts or a new block, and always make sure to use blocks that meet the working load limit (WLL) of your operation.
