Roller Bar Anchor Chain Cable Stopper with Hook | JIS F 2031 for 70–132mm Large

Product Specification

Roller Bar Anchor Chain Cable Stopper with Hook | JIS F 2031 for 70–132mm Large Anchor Chain

Product Overview

The 70–132mm roller bar type anchor chain cable stopper with hook is installed in the anchor chain route, normally in front of the windlass and aligned with the vessel’s anchor chain arrangement. It is used to clamp and hold large-diameter anchor chain so that the chain holding force can be transferred to the stopper foundation and ship structure instead of being carried continuously by the windlass.

The hook design allows the stopper to engage the anchor chain and work as an anchor-chain holding hook within the stopper arrangement. This page is written for large anchor chains from 70 mm to 132 mm, where chain fit, foundation strength, chain lead direction, material grade, surface treatment, and certificate scope should be confirmed before production. The product is an anchoring chain holding device, not a lifting hook or lifting appliance.

Quick Specifications

• Product type: Roller bar type anchor chain cable stopper with hook → chain holding arrangement for ship anchoring systems.
• Chain size range: 70–132 mm → suitable for large-diameter anchor chains where deck foundation and chain lead direction must be checked.
• Standard reference: JIS F 2031 → current cable stopper standard reference; JIS F 2032 may appear in legacy drawings and should be checked only for replacement compatibility.
• Hook function: anchor-chain holding hook → engages the chain link and helps secure the chain within the stopper arrangement; it is not a lifting hook.
• Main dimensions provided: h, h1, h2, L, L1, L4, B, b, and D → useful for deck layout, foundation checking, and quotation confirmation.
• Approximate weight range: 1,096–5,750 kg → important for shipyard handling, packing, transport, and installation planning.
• Material options: mild steel, C-Mn steel, stainless steel, cast steel, nodular cast iron, and steel forging → final material grade and manufacturing route should follow project requirement.
• Surface treatment: Sa 2.5 blasting + one layer epoxy shop primer, galvanized, polished, or customized treatment → final coating to match vessel specification.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm JIS F 2031 roller bar type anchor chain cable stopper with hook. If the project drawing still mentions old JIS F 2032, confirm replacement compatibility before quotation.

Step 2: Confirm nominal anchor chain diameter from 70 mm to 132 mm, chain grade, chain link geometry, and whether the stopper hook matches the actual chain link.

Step 3: Confirm installation position, chain lead direction, available deck space, foundation interface, deck reinforcement, and shipyard installation requirement.

Step 4: Confirm material requirement: mild steel, C-Mn steel, stainless steel, cast steel, nodular cast iron, steel forging, or project-specified material grade.

Step 5: Confirm surface treatment: Sa 2.5 blasting with epoxy shop primer, galvanized surface, polished stainless surface, final coating system, or special anti-corrosion requirement.

Step 6: Confirm certificate scope before quotation: maker certificate, material certificate, class certificate, witness inspection, or other project-specific approval requirement.

Step 7: Provide quantity, vessel type, installation drawing or reference photo, delivery destination, and required delivery time.

Structure

Roller bar stopper body | Anchor-chain holding hook | Large chain passage | Chain-contact area | Foundation base | Stopper engagement area | Surface treatment according to order

Chain Holding, Installation & Engineering Advantages

• The stopper is intended for large anchor chains from 70 mm to 132 mm, where chain holding, foundation arrangement, and ship structure load transfer require careful checking.
• The hook arrangement can engage the anchor chain link and work as an anchor-chain holding hook within the stopper assembly. Chain fit should be confirmed against the actual chain link size and chain grade.
• Positioning the stopper in front of the windlass helps transfer anchor chain holding force to the stopper foundation and ship structure when correctly secured according to the vessel operating procedure.
• The roller bar and chain-contact arrangement support chain alignment and reduce concentrated contact compared with a flat obstruction, while the final chain path must match the vessel arrangement.
• The high unit weight and large dimensions require planned handling, lifting during installation, transport packing, and shipyard foundation preparation.
• Material selection should be confirmed according to project load basis, chain size, corrosion environment, inspection scope, and class approval requirement.
• Surface preparation by Sa 2.5 blasting and shop primer provides a controlled base for subsequent coating; final paint system should follow the vessel coating specification.
• No SWL, test load, permissible load, or chain grade has been provided in the supplied data. These values should not be published until confirmed by standard drawing, calculation, or class-approved project document.

Custom Attributes

• Standard Reference: JIS F 2031 → use as the main page standard for cable stopper; old JIS F 2032 wording should be treated as legacy reference when found in older drawings.
• Type: Roller bar type with hook → stopper arrangement designed to hold large anchor chain in the anchoring system.
• Chain Size: 70–132 mm → select according to actual anchor chain diameter and chain link geometry.
• Hook Function: Anchor-chain holding hook → holds / secures the chain link within the stopper arrangement; not a lifting hook.
• Material: Mild steel, C-Mn steel, stainless steel, cast steel, nodular cast iron, or steel forging → final material grade should be confirmed before production.
• Surface Treatment: Sa 2.5 blasting + epoxy shop primer / galvanized / polished / customized → final surface finish follows the order and vessel specification.
• Installation Position: In front of the windlass in the anchor chain route → foundation, chain lead direction, and deck reinforcement should be confirmed by drawing.
• Certificate Requirement: Available according to project requirement → class inspection, material traceability, and approval scope should be confirmed before order.
• Customization: Available → customized material, coating, foundation interface, or inspection scope should be based on confirmed drawing and project requirement.

How It Works

Anchor chain passes through the stopper route → The hook and roller bar arrangement is engaged with the chain link → Chain holding force is transferred through the stopper body to the foundation and ship structure → The windlass is relieved from continuous holding load when the chain is correctly secured

Applications

Ship anchoring systems | Forecastle deck anchor arrangements | Large anchor chain 70–132 mm | Windlass protection arrangements | Newbuilding projects | Replacement and repair projects | Cargo vessels | Bulk carriers | Tankers | Container vessels

FAQ

Q1: Is the hook on this chain cable stopper a lifting hook?

A1: No. The hook is used as an anchor-chain holding hook within the chain stopper arrangement. It is intended to hold / secure the anchor chain link, not to lift cargo, lift equipment, or replace a certified lifting appliance.

Q2: How should the correct chain stopper size be selected?

A2: Select the size according to anchor chain diameter, chain link geometry, chain grade, vessel drawing, chain lead direction, installation space, deck foundation, and class requirement. The supplied table gives main dimensions and weight only; it does not provide SWL or test load.

Q3: What information is needed before quotation?

A3: Confirm the final standard designation, type, chain diameter, material grade, surface treatment, quantity, certificate requirement, installation drawing, vessel type, delivery destination, and required delivery time. If class witness inspection or calculation review is required, it should be stated before quotation.
