According to the driving method, marine capstans can usually be divided into two types: electric capstans and hydraulic capstans.

Electric capstan: The electric capstan uses an electric motor as the power source to drive the rotating shaft of the winch through electricity, thereby retracting and releasing ropes or cables. This type of capstan is usually suitable for small to medium-sized ships, with the advantage of relatively simple operation and easy control of speed and direction as needed.

Hydraulic capstan: The hydraulic capstan uses the hydraulic system as the power source. Hydraulic capstans can provide greater power output and are typically used in large ships or situations that require handling heavier loads. Compared to electric capstans, hydraulic capstans may require more maintenance and upkeep, but in some cases, they provide greater control and power output.

Both electric and hydraulic capstans are critical equipment on ships, used for various operations such as mooring, lifting and lowering anchors, and retracting ropes. The choice of capstan type suitable for specific ship needs depends on factors such as ship size, load requirements, operating environment, and available energy.
