Wooden Block 2 Sheaves Swiveleye & Accessories 5″ 14 Mm

This marine supply offers a wooden block with two sheaves and a swiveling mechanism, along with associated accessories. The 5-inch block, featuring a 14mm pin diameter, is essential for rigging and general deck operations on vessels, facilitating smooth rope or wire movement.

Wooden Block — This wooden block, complete with two sheaves and a swiveling eye, is a vital component of a ship's rigging equipment. The IMPA code 231651 identifies it within marine supply catalogs, ensuring accurate procurement for vessel maintenance. The unit of measure is 'PCE' (Piece), indicating it is sold individually. Wooden blocks are traditionally used to change the direction of pull on ropes or wires, reducing friction and easing handling.

The two sheaves (pulleys) increase mechanical advantage, making it easier to manage heavy loads. The swiveling eye prevents twisting of the rope or wire as it passes through the block, a critical feature for dynamic loads and rotating systems. Selection of a wooden block depends on the load it will bear and the environment it will operate.

Wooden Block — While modern vessels increasingly use metal blocks, wooden blocks remain suitable for certain applications, particularly where corrosion is a concern or where a softer material is preferred to avoid damage to delicate lines. The 5-inch size suggests a medium-duty application. Ensure that any connecting hardware is appropriately sized to match the pin diameter to prevent slippage or failure under load.

Wooden Block

Wooden Block — Incorrect sizing can compromise the integrity of the entire rigging system. Procurement of this block is typically part of a broader ship chandlery order, often triggered by routine inspections or the need to replace worn or damaged blocks. Regular inspection for cracks, splinters, or wear is also essential to maintain its safe operating condition. Proper lubrication of the sheave bearings can also extend its service life.

This type of block is commonly found in various deck operations, including sail handling, mooring lines, and general cargo securing. Its versatility makes it a valuable addition to a ship's inventory of essential rigging equipment. The inclusion of accessories suggests a complete package for immediate installation and use. Marine engineers and deck officers should familiarize themselves with the block's specifications and limitations to ensure its proper application and maintenance.

Understanding the load-bearing capacity and potential failure modes is crucial for safe vessel operations. This block represents a reliable solution for many rigging needs.
