ISO 13776 Deck Stand Pedestal Roller Fairlead | Single Roller Rope Guide for Ship Mooring and Towing

Product Overview

The ISO 13776 deck stand pedestal roller fairlead is a single-roller rope guiding fitting used on ship decks where a mooring or towing line needs to change direction around a vertical roller. The rotating steel roller helps guide the rope path and reduce sliding abrasion compared with a fixed contact surface, while the pedestal stand transfers rope reaction force into the deck structure through the welded base.

This page is prepared for ISO 13776 deck stand pedestal roller fairleads with nominal sizes Dn 150 to 500 and reference SWL values from the supplied data. The supplied project data states ISO 13776:2012 and ISO 13755 steel rollers; online ISO information shows ISO 13776:2020 and ISO 13755:2020 as current official editions, so the required standard edition should be confirmed before final quotation, drawing approval, and product marking.

Quick Specifications

• Product type: deck stand pedestal roller fairlead → single vertical roller guide for ship mooring and towing rope direction control.
• Technical standard: ISO 13776:2012 from supplied data → project edition should be confirmed because ISO 13776:2020 is listed online as the current edition.
• Roller standard: ISO 13755 steel roller → roller Type A / B / C affects the selected d dimension and roller interface.
• Nominal size range: Dn 150 to 500 mm → main selection range for deck stand fairleads in the supplied table.
• SWL reference range: 265 to 1942 kN at θ = 90° and 186 to 1373 kN at θ = 0° → reference rope tension values from supplied data, not lifting capacity.
• Height and weight reference: H = 500 / 1000 / 1500 mm → calculated weights are for reference and exclude the steel roller according to the supplied note.
• Material options: high tensile steel, stainless steel, casting steel, and nodular cast iron → final material grade and part allocation should be confirmed before production.
• Surface treatment: Sa 2.5 blasting + epoxy shop primer, galvanized, polished, or customized finish → final coating should follow project corrosion and inspection requirements.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm the required standard edition: ISO 13776:2012 as supplied, current ISO 13776 edition, or project-specific drawing requirement.

Step 2: Confirm fairlead type A / B / C, nominal size Dn 150 to 500, and ISO 13755 roller type because the d dimension depends on the selected steel roller type.

Step 3: Confirm rope direction, relative rope angle θ, required SWL marking, actual loading condition, and whether the product is used for mooring, towing line guidance, or replacement.

Step 4: Confirm deck stand height H, deck foundation, welding interface, welding leg length, chamfered welding requirement, reinforcement, and installation clearance.

Step 5: Confirm material grade for pedestal, roller, shaft, bush, and related parts; also confirm surface treatment, NDT scope, test requirement, and certificate requirement.

Step 6: Provide quantity, vessel type, installation drawing, rope path sketch, reference photo if available, delivery destination, and required delivery time.

Mooring, Towing & Engineering Advantages

• Single-roller pedestal design guides the mooring or towing line through a controlled direction change while helping reduce rope sliding abrasion on fixed deck structures.
• ISO 13755 roller compatibility gives a clear basis for selecting Type A / B / C roller interface dimensions, especially the d dimension listed in the supplied table.
• The SWL values are separated by rope-angle condition, which helps the buyer avoid treating one load value as universal for all lead angles and deck arrangements.
• Deck stand height selection affects rope lead height, deck clearance, maintenance access, and installation layout around mooring or towing equipment.
• Welding leg values Z1 and Z2 are provided for initial design and quotation reference; actual welding detail, chamfering, and deck reinforcement should follow the approved drawing.
• Smooth roller surface, correct shaft alignment, and suitable bush / bearing interface help the roller rotate with the rope and reduce unnecessary local wear.
• Casting, welding, machining, NDT, surface treatment, and certificate scope can be arranged according to order requirement, inspection plan, and class approval procedure.
• The page avoids describing the fairlead as a lifting device; it is a rope guiding fitting for ship mooring and towing line arrangements.

Custom Attributes

• Standard: ISO 13776:2012 from supplied data → confirm whether the project requires the supplied edition or the current ISO 13776 edition.
• Product Type: Deck stand pedestal roller fairlead → vertical single-roller rope guide installed on ship deck structures.
• Nominal Size: Dn 150 / 200 / 250 / 300 / 350 / 400 / 450 / 500 → select according to rope arrangement, SWL reference, and drawing requirement.
• Roller Type: Type A / B / C according to ISO 13755 steel rollers → affects roller interface and d dimension.
• SWL Reference: 265–1942 kN at θ = 90° and 186–1373 kN at θ = 0° → final marking should be agreed between user and manufacturer according to actual loading condition.
• Calculated Weight: H = 500 / 1000 / 1500 mm reference values → supplied note states the weight excludes steel roller.
• Material: high tensile steel / stainless steel / casting steel / nodular cast iron → exact material grade and certificate scope should be confirmed.
• Surface Treatment: Sa 2.5 blasting + epoxy shop primer / galvanized / polished / customized → final protection system follows project requirement.
• Certificate Requirement: available according to order scope → class certificate, material certificate, maker certificate, and witness inspection should be confirmed before quotation.

How It Works

Mooring or towing line approaches the pedestal fairlead → Rope bears against the single steel roller → Roller rotates and changes rope direction → Reaction force is transferred through the pedestal and welded base into the deck structure → Final SWL marking and inspection follow the agreed loading condition and project requirement

Applications

Ship deck mooring stations | Towing line guiding positions | Tugboats | Workboats | Cargo ships | Tankers | Bulk carriers | Offshore support vessels when specified by drawing | Newbuilding and replacement projects

FAQ

Q1: Is the SWL in the ISO 13776 table a lifting capacity?

A1: No. The supplied SWL values are reference maximum applicable rope tension values for pedestal fairlead rope deflection conditions. They should not be rewritten as lifting capacity, MBL, proof load, or test load.

Q2: How should the correct Dn size be selected?

A2: Select Dn according to the vessel drawing, rope lead angle, required SWL marking, deck stand height, roller type, installation space, foundation strength, and certificate requirement. The table is for initial selection and quotation confirmation.

Q3: Should the page use ISO 13776:2012 or ISO 13776:2020?

A3: The supplied data states ISO 13776:2012, while online ISO information lists ISO 13776:2020 as the current official edition. The edition used for quotation, drawing approval, and marking should be confirmed with the shipyard, owner, or class society.
