PURPOSE

The steering gears of ram type are installed on ships of various classes and purposes.

Our steering gears are easily interfaced with advanced control systems of home and foreign make.

Alarm and warning signal system ensures long-term maintenance-free continuous operation without local control.

 

DESIGN

The steering gear includes power drive; two main power units either of which provides the gear specification characteristics; remote electrical control system; control and signaling switchboards (sound, light and alarm); starting equipment; rudder indicator; system of filling and draining the steering gear.

The control system provides “Automatic”, “Follow-up” and “Non-follow-up” control modes.

The steering gear service life is not less than 25 years.
