Bow Thruster for Tug
The Electric Tunnel Bow Thruster for Tug enhances vessel maneuverability by generating adjustable lateral thrust (port/starboard) through a variable-speed electric drive system, improving navigation precision in tight spaces.
Working Principle
-
Power Transmission:
-
The electric motor delivers torque via a coupling to a reduction gearbox (helical/bevel gears).
-
Gears transfer power to the fixed-pitch propeller, converting rotation into directional thrust.
-
-
Speed & Thrust Control:
-
Variable Frequency Drive (VFD) regulates motor speed, enabling smooth thrust modulation.
-
Instant direction reversal for rapid side-to-side maneuvering.
