This series of pendulum-cylinder electro-hydraulic steering gear mainly includes a rudder pushing mechanism composed of two piston cylinders, two oil pump units, a storage tank, and an electric console. Operate the solenoid valve steering switch in the cab, control the hydraulic oil in and out of the cylinder through the electrical system, and push the rudder blade to achieve steering. When the power fails, the steering gear can be used for emergency steering. It is widely used in inland river rapid navigation areas, non-rapid current navigation areas, coastal fishing boats, and small sightseeing cruise ships.
