Thruster Control Systems

The Hydromaster Azimuth thruster control system provides hand follow-up control of both steering and propulsion and has an independent non-follow-up system for emergency and back up purposes.

The system is built from standard modular components and provides interfaces to diesel engines, electric or hydraulic motors as a source for propulsion. For steering, the system interfaces with a hydraulic or electric steering system.


Azimuth Control Lever
Rotates 360 degrees continuously around its vertical axis, providing full follow up steering control. Detents placed in the 0°, 90°, 180° and 270° position improve the sense of positioning. A propulsion lever offers clutch control and with a 80 degrees throw controls the propeller speed.
