Large Power Cable Reel Equipment ADJD-125/1-100-35 Used for Charging Big Vessel
Product Description
The ship cable management system produced by our company is specially designed for the use of shore power when the ship is berthed, to reduce the pollution of the ship to the port and to manage the cable collection, discharge and storage. When supplying power to the ship, the cable is automatically retracted and retracted, and connected to the shore-based power supply system ; In the absence of power supply, the cable is collected, stored and preserved to realize the comprehensive
protection function of the cable.
Cable management system is the ideal winding equipment in cable winding device at present. It is mainly composed of cable winch, cable length or tension automatic control equipment and related instruments to achieve constant tension automatic control.
It can realize the following main functions:
* The mechanical stress on the protection cable shall not exceed its allowable setting value;
* Eliminate the possibility of transmission of mechanical stress at the terminals of cable or conductor connections;
* Disconnect the shore connection circuit breaker quickly when the cable is overstretched. It can automatically collect, store and
release ship-shore connecting cables;
* Automatic control of constant tension in retracting and retracting cables;
* With emergency cut-off function. Alarm signal can be sent (the mechanical stress in the cable is too high or the length of the
remaining cable is too low);
* With safety interlocking function. Shore connection circuit breaker (installed in the onshore power distribution cabinet) should
not be closed or automatically disconnected in the closed position.
I. Cable Winch

3) Surface treatment: Marine anti-corrosion paint coating.
9. Drive components:
1) Shore-to-ship cable winch drive method: frequency conversion + hysteresis;
2) Shore-to-ship cable winch control method: linear tension control, providing ideal tension in real time according to changes in cable length and reel diameter;
10. Motor:
1) Frequency conversion brake motor (equipped with brake and encoder).
2) Motor electrical parameters (voltage: AC380V, 50HZ; power: not less than 4KW; speed: 1440r/min; protection level: IP56).
11. Hysteresis coupling (rated torque: greater than 18Nm; blackened surface treatment).
12. Reducer:
1) Speed ratio: 1:146
2) Paint: Marine anti-corrosion paint.
13. Low-pressure slip ring box:
1) Made of 316 stainless steel plate, thickness not less than 2.5~3mm. 2) Protection rating: IP56.
3) Rated voltage: 690V, 50-60HZ
Key Features and Components:
Robust Reel Drum: The core component is a sturdy, corrosion-resistant drum (often made from galvanized steel, powder-coated steel, or marine-grade aluminum) around which the shore power cable is wound. It is engineered to support the significant weight and diameter of the cable without deformation.
Manual Handwheel / Hand Crank: This reel is specifically equipped with a handwheel or hand crank for manual operation. This provides:
Precise Control: The operator can slowly and carefully pay out or retrieve the cable, preventing kinks, abrasion, or sudden drops that could damage the expensive, critical cable.
Reliability & Independence: No electrical power or hydraulic systems are required, making it highly reliable, low-maintenance, and functional in all situations.
Safety: The mechanical advantage offered by the handwheel allows a single person to manage a heavy cable with reduced physical strain and in a controlled manner.
Integrated Cable Guide (Close-up Mechanism): A defining feature is the integrated "close-up" or level-wind mechanism. This is a guide arm or traveler that moves along the axis of the reel as the handwheel is turned. It ensures the cable is wound evenly and tightly in uniform layers across the full width of the drum. This is crucial for preventing cable pile-up, jams, and damage during winding.
Sturdy Frame and Mounting Bracket: The reel is mounted on a heavy-duty frame, designed for permanent installation in a dedicated locker or on deck. It often includes swivel bearings for smooth rotation.
Marine-Grade Construction: All components are built to withstand harsh maritime environments. This includes resistance to saltwater corrosion, UV radiation, and extreme weather conditions through the use of appropriate materials, coatings, and seals.
Primary Functions and Advantages:
Cable Protection: Prevents the most common causes of cable damage: tangling, kinking, crushing, and abrasion against decks or docks.
Safety Enhancement: Reduces trip hazards on deck, organizes the connection path, and minimizes the risk of electrical damage to the cable insulation.
Operational Efficiency: Dramatically speeds up and simplifies the process of connecting to and disconnecting from shore power. A single crew member can safely handle the task.
Space Optimization: Provides a neat, fixed storage solution, keeping valuable deck space clear and the cable ready for immediate use.
Longevity: Extends the service life of the expensive shore power cable, providing a high return on investment.
Typical Applications:
Recreational yachts and motor vessels
Workboats, ferries, and patrol vessels
Commercial ships (fishing vessels, small cargo ships)
Naval auxiliary vessels
Any vessel requiring a frequent, reliable, and safe shore power connection.
In summary, this Marine Shore Power Cable Reel with Manual Handwheel and Close-up Guide is a vital piece of deck equipment that marries robust engineering with practical, safe, and user-friendly operation for one of a vessel's most critical port-side routines.
