Application

A marine electric capstan is a type of machinery that is used on ships and boats to handle heavy loads, such as anchors, mooring lines, and other types of ropes. It consists of a motor, gearbox, and drum, which is used to wind up the rope. The capstan is mounted on the deck of the ship, and the rope is usually led through a fairlead to the capstan head.

The electric motor powers the capstan, and the gearbox reduces the speed of the motor while increasing the torque, allowing it to handle heavy loads. The drum is usually grooved or has a surface texture to increase the friction between the rope and the drum, which allows the capstan to grip the rope and pull it in.

Marine electric capstan is driven by electric power and can be delivered with a one, two or three speed electric motorAccording to shaft center line orientation, there are electric vertical capstan andelectric horizontal capstan. Marine electric capstans are commonly used in maritime industries, such as shipping, fishing, and oil and gas exploration. They are often used in combination with winches to provide effective and efficient control over loads on board a vessel.

How To Choose The Marine Capstan?

Choosing the right marine electric capstan depends on several factors, including the intended use, the vessel's size and weight, and the environmental conditions. Here are some general considerations to help in the selection process:

1)Capacity: Determine the maximum load capacity that the capstan will need to handle, based on the vessel's size and weight, and the intended use of the capstan.

2)Speed: Determine the desired speed of the capstan, based on the vessel's operational requirements and the environmental conditions.

3)Power source: Determine the power source for the capstan, whether it will be powered by the vessel's electrical system, a dedicated generator, or some other power source.

4)Control system: Consider the type of control system needed for the capstan, whether it will be operated manually, with a remote control, or through an integrated control system.

5) Mounting: Determine the mounting method for the capstan, whether it will be mounted on the deck or below deck, and whether it will require a custom mounting arrangement.

6) Environmental conditions: Consider the environmental conditions where the capstan will be used, such as temperature, humidity, and exposure to saltwater and other corrosive elements.

7) Safety features: Look for safety features such as emergency stop buttons, overload protection, and other safety mechanisms.

8) Compliance with regulations and standards: Ensure that the capstan is designed and manufactured to comply with relevant regulations and standards, such as those from the International Maritime Organization (IMO), the RMRS, RINA, or other regulatory bodies.

9) Manufacturer reputation and support: Consider the reputation and support of the capstan manufacturer, including their experience and expertise in marine electric capstan design and manufacturing, as well as their level of customer support and service.

It is recommended to consult with a qualified marine electric capstan supplier or engineer to ensure that the capstan is properly selected for the vessel's intended use and that it complies with relevant regulations and standards.
