Marine Electrical Bow Thruster
Application
A marine electrical bow thruster is a type of propulsion system used in ships and boats to provide additional maneuverability and control. It is an electric motor-driven propeller that is mounted in a tunnel on the bow of the vessel. The electric motor provides power to the propeller, which generates a sideways force that can be used to turn the ship. Electrical bow thrusters can be controlled using a joystick or a computerized system, which allows for precise and smooth maneuvering of the vessel. They can also be integrated with other ship systems, such as GPS and autopilot, to provide seamless operation.
Features
1. Optimized combination of diameter-rotate speed of propeller, that improve propulsion efficiency; In the same thrust force we have smaller diameter, improve the ratio of utilization of cabin.
2. Skew blade and large disk ratio, reduce vibration and improve cavitation performance.
3. Gear and bearing have high strength and long longevity, and dipped into oil to got better lubrication and cooling effect, which improving the reliability of TP.
4. Underwater structure are optimized so that it have rational construction, which convenient for maintenance and repairing.
5. Tail shaft sealing are enough reliable sealing, meet the strict requirements of anti-pollution law of sea and ocean environment.
6. For extreme load conditions.
7. Low noise and vibration, installed vertically or horizontally, suitable for Transportation vessel, tugboat, ocean engineering vessel, ro/ro ship, cargo liner.
8. We can design and manufacture the product according to client's drawing or sample.
We not only provide customers with high-quality products, but also provide complete system solutions and added services for specific customers. Therefore, There are high competitiveness.

Maintenance advice
1. Regularly check whether there is leakage of hydraulic oil in the side thruster of the ship, regularly add tallow to the moving bearings and couplings, and replenish the hydraulic oil of the system in time.
2. Clean the dust in the ship's thruster control panel in time and check the working condition of the ACB.
If the ACB fails to close there are several reasons:
2.1. The control circuit has no electricity;
2.2. The main switch energy storage motor does not store energy normally;
2.3. There is no closing signal to the main switch closing coil;
2.4. The main switch under voltage coil has no electricity.
