Cast Steel Bar Type Anchor Chain Stopper for Ships | JIS F 2015

Product Specification

Cast Steel Bar Type Anchor Chain Stopper for Ships | JIS F 2015

Product Overview

The JIS F 2015 cast steel bar type anchor chain stopper is used in the ship anchoring arrangement between the chain hawse pipe and the windlass. It is a bar type stopper without a built-in roller, and it is fitted on a fabricated foundation so the installation height can be adjusted for proper chain path alignment.

For this product, the quality control of the sand mould cast steel body is a key manufacturing point. Casting soundness, dimensional accuracy, smooth chain-contact areas, bar seating condition, and the foundation interface should be controlled carefully because they affect installation matching, chain operation, and inspection acceptance. A separate chain wheel or roller is normally arranged in front of the stopper when the chain needs to be lifted smoothly into the windlass line.

Quick Specifications

• Product type: Cast steel bar type anchor chain stopper → used in ship anchoring arrangements between hawse pipe and windlass.
• Technical standard: JIS F 2015-1987 → reference standard for type designation and main dimensions.
• Chain size range: 38–78 mm → covers the listed anchor chain diameters for preliminary model selection.
• Structure: Bar type, without built-in roller → front chain wheel or roller should be confirmed separately when required.
• Installation basis: Fitted on fabricated foundation → foundation height can be arranged for chain alignment with hawse pipe and windlass.
• Manufacturing focus: Sand mould cast steel body → casting quality, chain-contact finishing, bar seating, and dimensional control are critical.
• Surface treatment: Sa2.5 blasting + one layer of epoxy shop primer → galvanized, polished, or customized treatment can be discussed by material and project requirement.
• Certificate scope: Maker certificate or classification certificate can be arranged according to project requirement and inspection scope.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm JIS F 2015-1987 bar type anchor chain stopper and the required chain diameter from 38 mm to 78 mm.

Step 2: Select the corresponding Type according to anchor chain diameter, then check A / B / C / D dimensions against the vessel anchor deck arrangement.

Step 3: Confirm fabricated foundation height, chain hawse pipe position, windlass chain wheel position, and whether deck reinforcement or class review is required.

Step 4: Confirm whether the front chain wheel or roller is included in the supply scope or arranged separately by the shipyard.

Step 5: Confirm material, casting inspection requirement, surface treatment, coating system, and certificate scope before quotation.

Step 6: Provide vessel type, installation position, quantity, delivery destination, required delivery time, and drawing or photos if available.

Casting, Installation & Quality Advantages

• Sand mould casting control is the main quality focus. The casting process should control shrinkage, cracks, harmful indications, and dimensional deviation within accepted marine casting criteria.
• Chain-contact surfaces and bar seating areas are dressed after casting to avoid sharp local contact and support smoother anchor chain engagement.
• The bar type arrangement is simple and does not include a built-in roller, which helps buyers separate the stopper supply scope from the front chain wheel or guide roller arrangement.
• The fabricated foundation allows the shipyard to adjust the installation height for alignment among hawse pipe, chain stopper, and windlass chain wheel.
• The size table covers 38–78 mm chain diameters, helping shipyards and repair yards compare chain size, envelope dimensions, and weight before quotation.
• Foundation strength, deck reinforcement, test load, and holding load requirements should be checked by the vessel designer or classification society because load data is not provided in the supplied parameter table.

Custom Attributes

• Standard: JIS F 2015-1987 → use when the vessel specification calls for JIS bar type anchor chain stopper dimensions.
• Type Range: 40 / 44 / 48 / 52 / 56 / 60 / 64 / 68 / 73 / 78 → select according to anchor chain diameter.
• Chain Size: 38–78 mm → final model should match the actual anchor chain specification and vessel drawing.
• Main Construction: Cast steel bar type → positioned as a cast steel stopper body; alternative material options require confirmation.
• Roller Arrangement: Without built-in roller → front chain wheel or roller is normally a separate arrangement unless included in the agreed supply scope.
• Installation: Fitted on fabricated foundation → foundation design and height adjustment should be confirmed by shipyard drawing.
• Surface Treatment: Sa2.5 blasting + epoxy shop primer → galvanized, polished, or customized treatment depends on material and project requirement.
• Certificate Requirement: Available according to project requirement → maker certificate, material certificate, class certificate, or witness inspection should be confirmed before order.

How It Works

Anchor chain leaves the hawse pipe → front chain wheel or roller lifts the chain when fitted → chain enters the bar type stopper → stopper bar secures the chain path → fabricated foundation transfers force to ship structure → chain is released for windlass operation when required

Applications

Ship anchoring arrangement | Anchor deck equipment | Hawse pipe to windlass chain path | Newbuilding projects | Repair and replacement projects | Fabricated foundation installation | Commercial vessels, workboats, tugboats, and barges according to vessel drawing

Certifications & Advantages

Certificates can be arranged according to project requirement, inspection scope, material traceability, and classification society approval procedure.

Certification: CCS, NK, BV, ABS, DNV, LR, KR, IRS, RS, RINA, CRS, Makers Test Certificate.

FAQ

Q1: How should the correct JIS F 2015 anchor chain stopper type be selected?

A1: Select the Type according to the actual anchor chain diameter, then check A / B / C / D dimensions, foundation height, hawse pipe alignment, and windlass chain wheel position against the vessel drawing.

Q2: Does this bar type chain stopper include a roller?

A2: No. The provided product description is a bar type anchor chain stopper without a built-in roller. A chain wheel or roller is normally arranged in front of the stopper when the chain needs to be lifted smoothly, but that supply scope should be confirmed separately.

Q3: What casting quality points are important for this stopper?

A3: Key points include casting soundness, dimensional accuracy, smooth chain-contact finishing, bar seating condition, foundation interface matching, and inspection scope. Load, test, and foundation requirements should be confirmed by the vessel design or class requirement.
