Tunnel Thruster / Bow Thruster / Fixed Pitch Tunnel Thruster

Tunnel Thruster :

The bow thruster includes one set of tunnel, propeller hub with blades, propeller shafting,

mesh gear, and driven shaft in it. The shipyard should install the thruster with the tunnel and the other parts.

The driven motor drives the driven shaft of the thruster, and the propeller shaft is rotated at low speed through the bevel gears And then the thruster will push the vessel toward the starboard or port, so it can improve the maneuverability.

Tunnel Thrusters are Fixed Pitch Propeller or controllable pitch propeller thrusters. 

The features as follows:-Superior Strength 
Tough and rational structural design has accomplished superior strength ,

Especially strong and durable driving shaft and seal are adopted for longer operation.
-Less Noise and vibration Employing thicker duct plate, 

developing new propeller design and so on have achieved less noise and vibration 

which follow comfortable living environment on board
-Easy Installation and Periodical Inspection
 is especially reduced duct lip and has a structure that it is able to weld 

anywhere on outer surface of duct for installation, On the periodical inspection, it is almost
not needed to change parts except seal.-Various type of driving
Compact new control system can provide easy operation. Customer can choose various configuration of prime mover, 

electric motor, diesel engine or hydraulic motor.
