Electric Vertical Capstan
Application
An electric vertical capstan is a type of capstan that is powered by an electric motor and is mounted vertically on a ship's deck or other structure. It is similar to a hydraulic vertical capstan in function, but it is designed to operate using an electric power source. Electric vertical capstans are used in a variety of marine applications, including anchoring, mooring, and towing. They are often found on large ships and vessels, but can also be used on smaller boats and other structures where heavy loads need to be moved or secured. It is important to note that proper safety procedures must be followed when using an electric vertical capstan, as the loads being handled can be very heavy and potentially dangerous if not properly secured. Additionally, regular maintenance and inspection of the capstan is necessary to ensure safe and reliable operation.

Cast iron
Cast iron has good casting performance, but when the carbon content of cast iron is relatively high, its performance is relatively brittle, and its tensile performance is relatively poor; it is easy to corrode and wear quickly, which is not conducive to load.
Q345D
The Q345D steel plate is preheated before welding to prevent the occurrence of cold cracks. And Q345D has good cold and hot working properties and corrosion resistance, and has good low temperature toughness. Conducive to load, slow wear.

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.
