26Q7297_REF DWG.pdf

This is a technical engineering drawing specification for bitts used in synthetic rope applications. The document provides detailed dimensional and design specifications for bitt barrels, webs, and top plates used in maritime rigging systems.

The drawing establishes comprehensive design parameters for multiple bitt configurations, including front elevation, side elevation, bottom view, and detailed cross-sectional specifications. Key specifications include precise measurements for bitt barrel diameters, web thickness, material composition requirements, and structural tolerances. The document references synthetic rope compatibility with WAVEX™ material per specification DSCIS-01-ETM-001 and establishes welding requirements with mandatory magnetic particle inspection. Material specifications include NTS steel designation, and the drawing incorporates a detailed dimension table providing measurements for various bitt sizes and configurations. The document includes general notes addressing maximum moment limitations, contact and chafing surface requirements, micro-inch finish specifications, and structural integrity requirements for bitt barrels and double plates. Additional specifications cover deviation tolerances, padeyе requirements, synthetic chock integration, and minimum safety factor requirements set at three for ultimate tensile loading. The references section cites the Bureau of Ships documentation, and a distribution statement indicates this is an unrestricted distribution document prepared by Superiors, Ohio.
