Wooden Block 2 Sheaves Swiveleye & Shackle 9″ 24 Mm

This wooden block assembly, featuring two sheaves, a swiveling eye, and a 9-inch shackle, is a crucial rigging component for marine vessels. Designed for heavy-duty applications, it facilitates smooth and reliable rope or wire rope guidance in various deck operations and vessel systems. Procurement of this item is essential for maintaining vessel functionality.

Wooden Block — This marine product is a wooden block, specifically designed for rigging applications on vessels. It incorporates two sheaves (pulleys), a swiveling eye, and a 9-inch shackle, all integrated into a single unit. The IMPA code 231654 identifies it within ship supply catalogs, and it is sold per piece (PCE).

Wooden blocks like this are traditionally used to change the direction of pull on ropes or wire ropes, reducing friction and making lifting or hauling operations easier. The two sheaves increase the mechanical advantage, allowing for heavier loads to be managed with less effort. The swiveling eye prevents twisting of the rope, which is particularly important for standing rigging and mooring lines.

The 9-inch shackle provides a secure and reliable connection point for attaching the block to other rigging components or vessel structures. Proper selection of the shackle size is critical to ensure safe operation. Wooden Block — Procurement professionals responsible for vessel maintenance and ship chandlery will find this block essential for various tasks, including mooring, anchoring, cargo handling, and sail handling on sailing vessels.

Wooden Block

Wooden Block — It’s a common item on a ship’s stores list, and readily available through marine supply channels. When selecting a wooden block, consider the anticipated load, the rope or wire rope diameter, and the environmental conditions. Regular inspection and maintenance are crucial for ensuring their continued safe operation. Handling considerations include avoiding sharp impacts that could damage the wood or the sheaves.

Proper lubrication of the sheaves will reduce friction and extend the block's service life. When installing the block, ensure that the shackle is properly secured and that the rope or wire rope is correctly seated in the sheaves. This type of block is often found in older vessels or in applications where a traditional, robust solution is preferred.

Modern synthetic materials are also used for blocks, but wooden blocks retain a place in marine rigging due to their strength and simplicity. Providing detailed specifications will ensure that the supplier provides the correct block for your application. Ultimately, this wooden block assembly represents a reliable and time-tested solution for rigging needs on a wide range of marine vessels, contributing to the safe and efficient operation of deck equipment and vessel systems.
