Simple Anchor Chain Releaser for Inland and Small Vessels | CB 531-66 Chain

Product Specification

Simple Anchor Chain Releaser for Inland and Small Vessels | CB 531-66 Chain Cable Clench Release

Product Overview

The CB 531-66 simple anchor chain releaser is a compact chain cable clench release device used in the anchor chain arrangement of inland vessels, small ships, workboats, and similar small marine applications. It is selected by nominal anchor chain diameter and is intended to hold the matching anchor chain size in the normal arrangement and allow chain release when the release device is operated.

This simple type is suitable where the vessel requires a straightforward anchor chain release fitting with easy installation, simple operation, and a size range from 17 mm to 37 mm nominal chain diameter. Material, surface treatment, installation interface, certificate scope, and any customized detail should be confirmed according to the vessel drawing and project requirement.

Quick Specifications

• Application focus: inland vessels and small vessels → simple installation and operation are the main selection advantages.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm CB 531-66 simple anchor chain releaser and select the size group according to nominal chain diameter: 17–19, 22–25, 28–31, or 34–37 mm.

Step 2: Confirm anchor chain grade, normally Grade 2 or Grade 3 according to the supplied specification, and provide the chain drawing or certificate if available.

Step 3: Confirm the vessel type and application position, especially for inland vessels, small ships, workboats, barges, or repair replacement projects.

Step 4: Confirm material requirement: C-Mn steel, stainless steel, or special material to be confirmed according to project specification.

Step 5: Confirm surface treatment: Sa 2.5 blasting + epoxy shop primer, galvanized finish, or customized coating according to vessel corrosion-protection requirement.

Step 6: Confirm certificate scope, quantity, delivery destination, required delivery time, installation drawing, and product photo if the order is for replacement.

Anchor Chain Release and Installation Advantages

• The simple configuration is suitable for inland vessels and small vessels where compact arrangement, easy operation, and straightforward installation are important.
• Four nominal chain diameter groups from 17 mm to 37 mm make the product convenient for small vessel newbuilding and replacement orders.
• The chain-contact area should be finished smoothly to reduce sharp local contact with the anchor chain links during holding and releasing.
• C-Mn steel is suitable for common marine equipment applications, while stainless steel can be discussed when higher corrosion resistance or a specific vessel requirement is specified.
• Sa 2.5 blasting with epoxy shop primer is suitable as a base corrosion-protection preparation; galvanized or customized surface treatment can be selected according to project requirement.
• Certificate and inspection scope should be confirmed before production, because class inspection, material traceability, and witness inspection depend on the vessel and order requirement.

Custom Attributes

• Standard: CB 531-66 → use when the vessel drawing or shipyard specification calls for this simple anchor chain releaser standard.
• Product Type: Simple anchor chain releaser → compact chain cable clench release device for anchor chain arrangements.
• Nominal Chain Diameter: 17–37 mm → select the correct row according to actual anchor chain diameter.
• Applicable Chain Grade: Grade 2 / Grade 3 → confirm the chain certificate and matching project requirement before order.
• Material: C-Mn steel / stainless steel → final material grade should be confirmed according to the order specification.
• Surface Treatment: Sa 2.5 blasting + epoxy shop primer / galvanized / customized → final coating follows project or vessel requirement.
• Application Vessel: Inland vessels and small vessels → suitable for compact anchor chain arrangements and repair replacement needs.
• Installation: Simple installation arrangement → exact mounting, bolt, weld, and surrounding structure details should be confirmed by drawing.
• Certificate Requirement: Available according to project requirement → class certificate and inspection scope should be confirmed before quotation.

How It Works

Anchor chain is led to the releaser → Chain is positioned in the clench / release seat → The selected chain size is held in the normal arrangement → Crew operates the simple release device when chain release is required → Correct chain size, installation, inspection, and operating procedure support safe use
