INSTRUCTIONS & CAUTIONS

Check Load Limits Before Use

Always verify the working load limit (WLL) of your single sheave marine cargo block before use. Exceeding the WLL can result in block failure, risking damage to your equipment and creating safety hazards. Make sure to stay within the specified load range for smooth and safe operation, even if the block can handle a higher ultimate load in testing.

Secure the Block Properly

When installing the marine cargo block, ensure it is securely fastened to a stable mounting point. The block should be aligned with the load direction to avoid unnecessary stress on the system. Loose or improperly mounted blocks can lead to misalignment, which may damage the block and reduce the efficiency of your rigging setup.

Inspect Regularly for Wear

Before each use, inspect the block thoroughly for any signs of damage, including cracks, corrosion, or wear on the sheave and bearings. Regular checks are crucial, especially after heavy lifting tasks or use in saltwater environments. Addressing wear early prevents costly repairs and ensures the block performs optimally for longer.

 

Lubricate and Maintain

For smooth operation, lubricate the sheave pin and head fitting regularly. This reduces friction, prevents premature wear, and ensures the block rotates freely. In marine environments, where salt and debris can accumulate, cleaning and re-lubricating the block is especially important. A well-maintained block runs efficiently and extends its lifespan, saving you time and money on replacements.
