CB/T 3062 Type A 3 Tube Rollers Universal Fairleads Ship Mooring Equipment

Marine 3 Roller Universal Fairlead for Compact Ship Mooring Rope Guiding | CB/T 3062 Type A

Product Overview

Marine 3 Roller Universal Fairlead is a compact and economical roller fairlead used for basic ship mooring and deck rope guiding applications. CB/T 3062 Type A is designed with two vertical rollers and one lower horizontal roller, helping the rope lead smoothly from three directions while reducing direct rope contact with the deck structure.

Compared with 5-roller, 7-roller or 9-roller fairleads, the 3-roller type is not intended to represent a complex multi-direction heavy-duty arrangement. Its value is a simpler structure, smaller installation footprint, easier maintenance and lower project cost, making it suitable for small and medium vessels, auxiliary mooring positions and general rope guiding layouts where the rope path is relatively clear.

Quick Specifications

• Product type: CB/T 3062 Type A 3 Roller Universal Fairlead → compact basic roller fairlead for ship mooring rope guiding.

• Roller arrangement: 2 vertical rollers + 1 lower horizontal roller → guides the rope from three practical directions and reduces local friction.

• Nominal size range: 100 to 320 → covers steel wire rope diameters from 14 to 44 mm and nylon rope diameters from 36 to 100 mm.

• SWL range: 54 to 533 kN according to the provided parameter table → size selection should follow vessel drawing and mooring arrangement.

• Weight range: 112 to 2122 kg → useful for deck arrangement, lifting during installation, packing and freight estimation.

• Material options: C-Mn steel, mild steel or stainless steel according to order → final material and certificate scope should be confirmed before quotation.

• Surface treatment: blasting to Sa2.5/S2.5 as specified + epoxy shop primer, galvanized, polished or customized coating → selected according to vessel coating system.

• Positioning: economical 3-roller solution for basic rope guiding → not the same product positioning as multi-roller 5 / 7 / 9 roller fairleads.

Selection & Inquiry Guide

• Step 1: Confirm CB/T 3062 Type A and nominal size according to vessel drawing, steel wire rope diameter or nylon rope diameter.

• Step 2: Confirm the rope leading direction and installation position. This 3-roller type is suitable for basic rope guiding rather than complex multi-angle heavy-duty rope paths.

• Step 3: Confirm SWL requirement, rope type, rope diameter, deck arrangement and available foundation space before production.

• Step 4: Confirm material requirement: C-Mn steel, mild steel, stainless steel or project-specified material.

• Step 5: Confirm surface treatment: blasting and shop primer, galvanized finish, polished stainless steel surface or complete marine coating system.

• Step 6: Confirm certificate requirement, quantity, destination, required delivery time, and provide vessel drawing or reference photos if available.

Structure

Two vertical rollers | One lower horizontal roller | Compact supporting frame | Roller shafts | Bushing / bearing position to be confirmed | Deck-mounted foundation | Marine coating or project-specified surface treatment

Design, Installation & Maintenance Advantages

• The 3-roller arrangement provides a simple rope lead for normal mooring positions where a full multi-roller fairlead is not required.

• The compact structure helps reduce occupied deck space, making it suitable for small and medium vessels or auxiliary mooring locations.

• Rollers reduce direct rope contact with fixed steel structures, helping lower friction and protect the rope surface during mooring operation.

• The Type A arrangement with two vertical rollers and one lower horizontal roller supports rope guidance from practical deck-level directions.

• Compared with higher roller-count fairleads, the structure is easier to inspect, repaint, lubricate and maintain.

• Material, coating and certificate scope can be arranged according to order, vessel specification and class approval procedure.

Custom Attributes

• Standard: CB/T 3062-2011 Type A → used when the project specification requires the Chinese marine universal fairlead standard.

• Product Positioning: Basic compact 3-roller fairlead → suitable for ordinary rope guiding, not for complex multi-direction 9-roller applications.

• Roller Quantity: 3 rollers → two vertical rollers and one lower horizontal roller for a simple and economical guiding structure.

• Rope Range: Steel wire rope 14–44 mm / nylon rope 36–100 mm → select by vessel mooring plan and rope specification.

• SWL: 54–533 kN according to nominal size → do not replace project verification, deck structure review or class approval where required.

• Material: C-Mn steel / mild steel / stainless steel → final grade, traceability and certificate should be confirmed before order.

• Surface Treatment: Blasting + shop primer / galvanized / polished / customized → coating system should match the vessel corrosion protection requirement.

• Certificate Requirement: Available according to project requirement → class certificate and inspection witnessing are subject to order scope and class approval.

How It Works

Rope approaches the fairlead → Vertical and horizontal rollers guide the rope path → Roller rotation reduces direct friction → Rope load is transferred through the fairlead frame to the deck foundation → Inspection and lubrication keep roller movement reliable

Applications

Ship mooring system | Deck rope guiding | Small and medium vessels | Workboats | Inland vessels | Auxiliary mooring positions | Winch rope lead | Newbuilding and replacement projects

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: What is the main positioning of a 3 roller fairlead?

A1: A 3 roller fairlead is a basic, compact and economical rope guiding product for normal ship mooring positions. It is not the same as 5-roller, 7-roller or 9-roller fairleads used for more complex rope paths.

Q2: How should the correct nominal size be selected?

A2: Select the size according to the rope type, rope diameter, SWL, vessel deck arrangement and installation drawing. The provided table gives the main selection range from nominal size 100 to 320.

Q3: Can the material, bearing and coating be customized?

A3: Material and surface treatment can be confirmed according to project requirement. Bearing or bushing arrangement, lubrication detail and certificate scope should be confirmed by drawing, order specification and inspection requirement.
