Hydraulic Mooring Capstan



Application

A Hydraulic Mooring Capstan is a type of machinery used in marine and offshore operations for mooring a vessel. The capstan is a horizontally oriented winch that rotates a drum around which a cable or rope is wrapped. Unlike electric capstans, hydraulic capstans are powered by hydraulic motors. Hydraulic Mooring Capstans are designed for heavy-duty mooring applications, such as towing, salvage operations, and offshore construction. The hydraulic power source provides high torque and efficient power transfer to the capstan, making it suitable for use with larger vessels and heavier loads.

Capstan precautions

1. First of all, the reasonable method in the dragging process is to fix the traction point, fix the body, and skillfully use tools such as tree-hugging belts and ground spears to ensure the reliability of the clutch switch.

2. Ensure that the towing vehicle and the towed vehicle are in a straight line. The angled traction will firstly offset the traction force, and secondly, the steel cable of the winch will be wrapped around one end. If the angle cannot be adjusted, the directional pulley can be used.

3. When pulling objects, if you need to loosen the steel cable, you should use the loosening button with caution, which will easily cause the steel cable to be knotted and entangled on the reel. You can use the clutch to stretch the cable as straight as possible.

4. When dragging heavy objects or vehicles that are difficult to drag, a pulley block can be used to form a loop to increase the traction.

5. A spare battery is also required. The winch can quickly run out of battery power. Double batteries are necessary, and the second battery can be made larger.

6. Wear gloves when operating the winch cable, and place rubber pads and other items on the cable to prevent destructive rebound after the winch cable breaks.

7. When using the winch to pull heavy objects or vehicles, always pay attention to the battery voltage. If the battery voltage is too low, stop the operation immediately, and increase the battery voltage by increasing the engine speed to force the generator to charge. Because the power of the winch motor is rated, the lower the voltage, the greater the current that breaks down the battery and the control relay, and the forced use of low voltage is easy and faster to reduce the life of the battery and the relay in the control box. In the case of low voltage, the rope retraction speed will also be slower.

8. The winch should be rigidly connected to the most solid and reliable place of the car body to avoid separation from the car body or other dangers during towing.
9. If the time is tight and the neatness of the rope cannot be guaranteed, it is also necessary to release the rope fence when conditions permit and rewind the rope fence neatly on the reel. Avoid long and messy winding of the rope fence.
