Product Specification

Marine Manual Coupling Winch | Hand Operation Winch for Ship Deck Equipment

Product Overview

The single drum hand coupling winch is a manually operated deck winch used for rope handling, light pulling, positioning, and holding work on barges, inland waterway ships, workboats, and small deck arrangements where electric or hydraulic power is not required. It is operated by a handwheel or lever handle, with gear transmission and a ratchet or brake arrangement used to control movement and hold rope tension during operation.

This product should be positioned as a manual rope-handling and holding winch, not as a powered towing winch, lifting winch, or personnel-lifting appliance unless a specific certified design is supplied for that duty. The supplied data gives safety pull capacity, holding load, single drum arrangement, optional brake or ratchet, and customized drum capacity. Rope diameter, drum size, gear ratio, mounting base, hand force, and certificate scope should be confirmed before quotation and production.

Quick Specifications

• Product type: Single drum manual hand coupling winch → suitable for manual deck rope handling and holding applications.

• Safety pull capacity: 5–100 kN → used as the main pulling selection parameter; it should not be converted into SWL, MBL, or towing capacity without approved calculation.

• Holding load: 50–1000 kN → relates to the holding device or brake/ratchet arrangement; it is not the same as manual pulling capacity.

• Drum capacity: Customized → rope diameter, rope length, fleet angle, drum width, and flange height must be confirmed for each project.

• Operation method: Handwheel or handle lever → suitable where simple manual operation and local control are required.

• Holding device: Brake or ratchet → used to prevent uncontrolled drum rotation when rope tension is being held.

• Construction: Single drum with gear transmission → gear ratio and speed change should be confirmed according to pull force and hand force requirement.

• Surface treatment: Sa 2.5 blasting + 3-layer epoxy paint or galvanized finish → final coating follows marine environment and project specification.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm the required safety pull capacity within 5–100 kN according to rope handling duty, expected line tension, and actual working condition.

Step 2: Confirm the holding load requirement and whether the winch needs a ratchet device, mechanical brake, or both. The holding load should be checked separately from the pulling capacity.

Step 3: Confirm rope type, rope diameter, rope length, and required drum capacity. The drum width, flange height, rope layer number, and rope anchoring method should be confirmed by drawing.

Step 4: Confirm operation method: handwheel, handle lever, gear-change arrangement, operator position, and acceptable hand force for one-person operation.

Step 5: Confirm deck mounting arrangement, base footprint, bolt or weld detail, surrounding clearance, and whether the installation is for newbuilding, replacement, barge, or inland waterway vessel.

Step 6: Confirm material, surface treatment, stainless steel option, galvanized finish, coating system, certificate requirement, quantity, destination, and delivery requirement.

Manual Operation, Gear & Holding Advantages

• Manual operation allows rope handling in locations where hydraulic or electric power is not available or where a simple local operating device is preferred.

• Gear transmission can provide mechanical advantage for higher pulling effort, while gear change can be used for faster slack take-up or easier winching depending on the design.

• A ratchet pawl, holding dog, or brake arrangement helps hold rope tension and reduce the risk of uncontrolled reverse drum rotation during operation.

• Single drum construction is simple to inspect and maintain, making it suitable for barges, inland waterway vessels, and small deck equipment arrangements.

• The operator position, handwheel radius, handle lever length, gear cover, and surrounding clearance should be checked so that manual operation is practical and safe.

• This page does not present the winch as lifting equipment. Lifting, personnel lifting, or load-supporting duty requires a separate certified design, approved brake system, and project-specific verification.

Custom Attributes

• Product Type: Single drum manual hand coupling winch → deck-mounted manual rope-handling winch for ship and barge applications.

• Pulling Range: 5–100 kN → select according to operating load and rope-handling duty.

• Holding Range: 50–1000 kN → confirm brake or ratchet rating, test basis, and safety factor before use in engineering selection.

• Drum Capacity: Customized → rope diameter and required rope length determine drum dimensions.

• Operation: Handwheel or handle lever → choose according to operator access and required hand force.

• Speed / Gear: Gear-change arrangement to be confirmed → higher speed for slack take-up and lower speed for heavier pulling may be considered when specified.

• Material: Mild steel or stainless steel → exact grade and material certificate scope should be confirmed.

• Surface Treatment: Epoxy paint system or galvanized finish → select according to vessel area, corrosion exposure, and maintenance requirement.

• Certificate Requirement: Available according to order scope → maker certificate, material certificate, class certificate, or witness inspection should be confirmed before quotation.

How It Works

Operator turns the handwheel or handle lever → Gear transmission drives the single drum → Rope is wound in or paid out under control → Ratchet, holding dog, or brake holds the drum when required → Rope tension is transferred through the drum shaft, frame, and mounting base to the deck structure

Applications

Barges | Inland waterway ships | Small workboats | Service vessels | Shipyard rope handling | Mooring line adjustment | Deck utility rope handling | Replacement of manual deck winches

Certifications & Advantages

FAQ

Q1: How should the correct manual hand coupling winch be selected?

A1: Select the winch according to safety pull capacity, holding load, rope type, rope diameter, rope length, drum capacity, operation method, gear ratio, brake or ratchet requirement, and deck installation condition. For replacement projects, the existing foundation and rope lead should also be checked.

Q2: What is the difference between safety pull capacity and holding load?

A2: Safety pull capacity refers to the pulling selection parameter for manual winching. Holding load refers to the capability of the holding device, ratchet, or brake arrangement to hold rope tension. These two values should not be mixed, and the exact test basis should be confirmed before engineering approval.

Q3: Can this manual winch be used as a lifting winch?

A3: Not by default. This page describes a manual deck rope-handling winch. Lifting or personnel-related use requires a specific certified lifting design, approved brake arrangement, load testing, and class or authority approval according to the project requirement.
