Shipside Horizontal Roller Fairlead for Ship Mooring | CB/T 435 Type A

Product Specification

Shipside Horizontal Roller Fairlead for Ship Mooring | CB/T 435 Type A

Product Overview

The CB/T 435 Type A shipside horizontal roller fairlead is a side-mounted mooring rope guiding unit used in the horizontal roller position, normally installed at the vessel side and used together with a shipside double roller fairlead or roller chock. Its function is to guide the mooring rope and help change the rope lead angle in the vertical direction, reducing local abrasion when the rope direction changes between the ship side and deck mooring arrangement.

This Type A configuration uses a roller, roller shaft, bearing bush, spacer, bearing seat, stop plate, and lubrication-groove bearing design. The 120 mm high bearing seat is welded to the roller fairlead structure, while the stop plate fixes the roller shaft in position. For procurement and replacement, the main confirmation points are CB/T 435-2005 Type A, roller diameter, material, surface treatment, matching shipside roller chock arrangement, and certificate requirement.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm CB/T 435-2005 Type A shipside horizontal roller fairlead and select nominal diameter 75 or 89 according to the vessel drawing.

Step 2: Confirm the rope lead arrangement: shipside installation position, vertical lead angle change, and matching shipside double roller fairlead or roller chock.

Step 3: Confirm material and roller option: C-Mn steel, mild steel, stainless steel, or FRP roller if required by the project.

Step 4: Confirm surface treatment: Sa 2.5 blasting + epoxy shop primer, galvanized finish, polished stainless steel surface, or other coating system.

Step 5: Confirm inspection and certificate scope before quotation: maker certificate, material certificate, class witness inspection, or class certificate according to project requirement.

Step 6: Provide quantity, vessel type, installation drawing or photo, delivery destination, and required delivery time.

Mooring Design, Rotation & Engineering Advantages

• The Type A shipside arrangement is suitable where the mooring rope changes direction between the ship side guide and the deck mooring equipment, especially when used with a shipside double roller fairlead or roller chock.
• The horizontal roller helps guide the rope in the vertical direction and reduces direct rubbing against fixed steel edges during mooring operation.
• The bearing bush includes a lubrication groove to support flexible roller rotation and reduce maintenance difficulty during service.
• The stop plate fixes the roller shaft and helps keep the roller assembly in its designed position during normal rope guiding operation.
• The 120 mm high bearing seat provides a defined support height and welded interface for integration with the roller fairlead structure.
• Material and surface treatment can be selected according to vessel environment, corrosion requirement, maintenance plan, and customer specification.
• No SWL or rope MBL is declared in the supplied parameter table. Load selection should be checked against the vessel mooring arrangement, rope data, and project drawing when required.

Custom Attributes

• Standard: CB/T 435-2005 → used for Type A shipside horizontal roller fairlead selection and main dimension reference.
• Type: Type A shipside type → suitable for installation at the vessel side and use with shipside roller chock arrangements.
• Nominal Dia.: 75 / 89 mm → select according to project drawing, roller diameter, and available installation space.
• Roller Diameter: 76 / 89 mm → main rope-contact roller size for webpage drawing and quotation confirmation.
• Material: C-Mn steel / mild steel / stainless steel / FRP roller option → final selection should be confirmed by project specification.
• Bearing Design: bearing bush with lubrication groove → supports smoother rotation and maintenance access.
• Bearing Seat: 120 mm high welded bearing seat → project drawing should confirm surrounding structure and installation interface.
• Certificate Requirement: available upon request according to project requirement → class inspection scope should be confirmed before order.

How It Works

Mooring rope approaches the shipside guide → Rope contacts the horizontal roller → Roller rotation guides the rope and changes the vertical lead angle → Bearing bush and lubrication groove support flexible rotation → Rope continues toward the matching shipside roller chock or deck mooring equipment

Applications

Ship side mooring stations | Shipside roller chock arrangements | Double roller fairlead matching use | Mooring rope vertical angle guidance | Cargo ships | Workboats | Tugboats | Newbuilding and replacement projects

FAQ

Q1: What is the main function of the CB/T 435 Type A shipside horizontal roller fairlead?

A1: It is used at the ship side to guide the mooring rope and help change the rope lead angle in the vertical direction. It is normally used together with shipside roller chock or double roller fairlead arrangements.

Q2: Is the supplied roller diameter the same as product SWL?

A2: No. Roller diameter and main dimensions are not SWL. The supplied data includes nominal diameter, roller diameter, shaft diameter, length, and weight. Any load basis should be confirmed from vessel mooring calculation, rope data, project drawing, or class requirement.

Q3: What should be confirmed before ordering Type A?

A3: Confirm CB/T 435-2005 Type A, nominal diameter 75 or 89, matching shipside fairlead / roller chock arrangement, material, surface treatment, certificate requirement, quantity, installation drawing, delivery destination, and delivery time.
