10–20 kN Electric Accommodation Ladder Winch | ISO 7364 Ship Deck Boarding

Product Specification

10–20 kN Electric Accommodation Ladder Winch | ISO 7364 Ship Deck Boarding Ladder Handling Equipment

Product Overview

The 10–20 kN electric accommodation ladder winch is a ship deck machinery item used for lowering, hoisting, and securing an accommodation ladder during boarding arrangements. It is arranged with an electric drive, gearbox transmission, drum, wire rope system, brake / holding device, manual backup drive, and local control equipment. The winch selection should be checked together with ladder type, drum load, supporting load, wire rope capacity, installation position, power supply, control arrangement, and the vessel’s boarding arrangement drawing.

The supplied product name uses “pilot ladder winch”, but standard checking shows that ISO 7364:2016 is titled for accommodation ladder winches, while pilot ladder winch reels are covered separately by ISO 24136:2021. Therefore this page positions the product as an ISO 7364 electric accommodation ladder winch. If the actual project is for a pilot ladder winch reel, ISO 24136, SOLAS V/23, IMO pilot transfer requirements, and the vessel’s approved pilot transfer arrangement should be confirmed before final quotation.

Quick Specifications

• Product type: electric accommodation ladder winch → deck machinery for controlled ladder lowering, hoisting, holding, and stowage.

• Standard basis: ISO 7364:2016 → official ISO scope is accommodation ladder winches; pilot ladder winch reels should be checked under ISO 24136:2021.

• Nominal drum load: 10 / 16 / 20 kN → selection should follow ladder weight, rope reeving, drum load, and approved ship arrangement.

• Supporting load: 30 / 48 / 60 kN → used as supplied selection data and should not be rewritten as lifting SWL for personnel.

• Hoisting speed: 8.09–20.7 m/min according to supplied model data → final speed should match boarding operation and safe control requirement.

• Wire rope: 6×37-13.0-170-1 as supplied → exact rope standard, tensile grade, galvanizing, and certificate scope should be confirmed.

• Wire capacity: 37 / 50 / 95 m → important for ladder travel, drum layer control, and available ship-side height.

• Drive and backup: electric motor drive with manual operation → manual drive is used for emergency or power-failure recovery according to project arrangement.

• Factory testing: no-load running test, drum load test, and static holding test can be arranged according to order scope and inspection requirement.

• Surface treatment: Sa 2.5 blasting + epoxy coating as reference → final coating system follows vessel specification or customer requirement.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm whether the project requires an ISO 7364 accommodation ladder winch or a pilot ladder winch reel. This point should be clarified first because ISO 7364 and ISO 24136 cover different equipment.

Step 2: Confirm nominal model: 10 kN, 16 kN, or 20 kN according to accommodation ladder weight, rope reeving, travel height, stowage position, and approved boarding arrangement.

Step 3: Confirm single-drum or double-drum arrangement, wire rope capacity, winding layer requirement, drum orientation, and left-hand / right-hand layout if applicable.

Step 4: Confirm drive and control: electric motor specification, power supply, local control station, emergency stop, manual backup access, and any remote-control requirement.

Step 5: Confirm safety and inspection scope: brake / holding device, static holding test, no-load running test, drum load test, material certificate, class witness, and acceptance criteria.

Step 6: Provide ladder drawing, winch foundation drawing, deck arrangement, available installation space, quantity, certificate requirement, delivery destination, and required delivery time.

Structure

Boarding Equipment, Drive & Safety Advantages

• The electric drive provides controlled drum rotation for lowering and recovering the accommodation ladder, while the gearbox ratio is selected to match the drum load and operating speed.

• The manual backup drive allows recovery operation when electric power is not available, but its access, operating clearance, and handle arrangement should be confirmed by the ship arrangement drawing.

• The brake or holding device is a critical safety part. Its holding capacity, static test load, release method, and inspection scope should be confirmed before production.

• Wire rope capacity and winding layers affect safe travel and stowage. Excessive rope layering or incorrect rope lead may cause uneven winding, rope damage, or reduced operational reliability.

• For ISO 7364 accommodation ladder winches, the equipment is intended for ladder handling and holding. It should not be marketed as a general-purpose lifting winch or personnel hoisting device.

• If used in a pilot transfer arrangement, the winch reel position must not obstruct safe access, and the actual arrangement should follow the approved pilot transfer arrangement and applicable flag / class requirement.

• No-load running test, drum load test, static holding test, and class inspection can be arranged according to order scope, but test values and acceptance criteria must be agreed before quotation.

Custom Attributes

• Standard: ISO 7364:2016 → applies to ships’ accommodation ladder winches; confirm ISO 24136 if the project is for pilot ladder winch reels.

• Nominal Model: 10 / 16 / 20 kN → select by drum load, supporting load, ladder arrangement, and wire rope capacity.

• Drum Type: single drum or double drum → follow ladder type and ship boarding arrangement.

• Hoisting Speed: 8.09–20.7 m/min from supplied data → confirm required operating speed and control method before order.

• Wire Rope: 6×37-13.0-170-1 → supplied rope specification; final rope grade, finish, certificate, and safety factor should be confirmed.

• Drive Type: electric motor drive → motor power, voltage, frequency, insulation class, and marine electrical requirement should be confirmed.

• Manual Backup: available according to configuration → used for recovery operation when electric drive is unavailable.

• Control: local control as supplied → remote control, limit switch, emergency stop, or interlock requirement should be stated if required.

• Surface Treatment: Sa 2.5 blasting + epoxy coating → final coating, color, and corrosion protection follow vessel specification.

• Certificate Requirement: available according to order scope → class certificate, maker certificate, material certificate, and witness report should be confirmed before production.

How It Works

Operator activates local control → Electric motor drives the gearbox and drum → Wire rope pays out or winds in to lower or recover the accommodation ladder → Brake / holding device secures the drum when stopped or in stowage condition → Manual backup can be used for emergency recovery according to the approved operating procedure

FAQ

Q1: Is ISO 7364 a pilot ladder winch standard?

A1: No. ISO 7364:2016 is the ISO standard for accommodation ladder winches. If the project is for a pilot ladder winch reel, ISO 24136:2021 and the applicable pilot transfer arrangement requirements should be checked before final technical confirmation.

Q2: Can this winch be used for man lifting?

A2: It should not be described as a man-lifting winch. The winch is for accommodation ladder handling and holding. Personnel transfer safety depends on the complete approved ladder arrangement, access platform, securing points, operating procedure, and class / flag approval.

Q3: What information is needed before quotation?

A3: Confirm standard basis, nominal model, ladder drawing, drum type, wire rope capacity, power supply, control method, installation foundation, manual backup arrangement, test requirement, certificate scope, quantity, delivery destination, and required delivery time.
