160 KW Bow Thruster:
1. 160 KW Bow Thruster Main function
The main function of this device is to make the power and torque of the motor through the coupling and a pair of speed reducing circular arc bevel gears to the fixed propeller, control the rotation speed and direction of the variable-frequency motor through variable frequency speed regulation, and then make the propeller generate the thrust force towards the port side or the starboard. No matter the degree of thrust force can be adjusted or not, it can raise the mobility and maneuverability at ship navigation.
This device applies to the unrestricted navigation area, the bow thruster cylinder, the grid should be set at the entrance.
