Manual Marine Drum Winch

Core Engineering Design (Why It Works)

1. Optimized Dual-Piping Design (Pressure vs. Return)

• Pressure Side: 3/4 inch (19.05 mm)
• Return Side: 1 inch (25.4 mm)
• The Logic: This configuration strictly matches the flow difference between hydraulic supply and return. The larger return line prevents restricted flow, eliminating issues like system backpressure buildup, rapid temperature rise, and premature seal failure.

2. High-Pressure Rotary Swivel System

• Built-in high-pressure slip ring allows for stable oil supply while the reel is rotating.
• Benefit: Solves common problems found in direct-connect reels, such as hose tangling, joint fatigue from repetitive stress, and safety risks associated with manual hose organization.

3. 1:1 Manual Drive with Unidirectional Ratchet Brake

• Direct Drive: 1:1 hand-crank structure ensures linear operation and controlled force application.
• Safety Braking: Equipped with a unidirectional ratchet mechanism that locks the reel stably at any position.
• Benefit: Prevents safety hazards caused by inertia or loss of control during high-pressure hose retraction, making it ideal for manual operation scenarios.

Construction & Durability (Built for the Ocean)

• 🛡️ Marine-Grade Anti-Corrosion: Coated with Epoxy Zinc-Rich paint (Film thickness ≥200 μm), significantly enhancing rust and corrosion resistance in salt spray and humid environments.
• 🔩 Stainless Steel Components: All fasteners and interface components are made of Stainless Steel (SS) to prevent pitting and structural fatigue.
• 🌀 Hose Protection: Includes a 150 ft Pigtail Spiral Guard to provide mechanical protection, reducing bending fatigue and extending the overall life of the high-pressure hose.
• 🏗️ Site-Ready Design: Integrated forklift slots and lifting lugs facilitate easy hoisting, transport, and rapid deployment on engineering sites.

Frequently Asked Questions (FAQ)

Q1: What specific engineering scenarios is this manual reel suitable for? A: This product is specifically designed for marine engineering and high-pressure hydraulic systems. It is ideal for:

• Maintenance of offshore platform hydraulic systems.
• Refueling and oil return for ships.
• Mobile high-pressure hydraulic devices.
• Work environments where no power source is available or explosion-proof standards are required. (Note: For remote automation or high-frequency automatic cycles, an electric reel is recommended).

Q2: How does this reel ensure the safety of the hydraulic system? A: We ensure safety through three key designs:

1. Dual-Piping Match: The 3/4" pressure and 1" return lines match flow rates to prevent backpressure and overheating.
2. Rotary Swivel System: Allows continuous supply while rotating, preventing hose tangling and joint fatigue.
3. Ratchet Braking: The 1:1 manual drive with a ratchet brake allows the reel to be locked securely at any position, preventing uncontrolled spooling.

Q3: What anti-corrosion features are included for harsh environments? A:

• Coating: Marine-grade Epoxy Zinc Rich coating with a thickness ≥200 μm to resist salt spray.
• Hardware: Stainless steel fasteners and interfaces to resist pitting.
• Hose Guard: A 150-ft spiral guard protects the hose from mechanical wear and bending fatigue.

Q4: Is the operation difficult? Does it require a power source? A: No power is required. It is a purely manual device, making it perfect for hazardous or remote zones. The operation utilizes a 1:1 direct drive for linear control, allowing the operator to precisely manage speed. The integrated ratchet brake ensures the hose can be locked safely at any length.

Q5: What is the core value of this product compared to a standard reel? A:

• Safety First: Eliminates tangling and uncontrolled retraction risks.
• Durability: Built with heavy-duty coatings and stainless steel for long life.
• Engineering Focus: Unlike simple hose winders, this is a professional solution for high-pressure hydraulic management, ensuring reliable oil delivery without the need for electricity.
