Hydraulic Ram Type Marine Steering Gear (four cylinders with twin piston and one tiller type) consists of two sets of reciprocating and fork type rudder mechanism, two sets of motor kinetic tank for oil pump, one reserve tank. Control mode, including electronic control, pump control, can be used together with any form of autopilot or follow-up pilot. To meet cunstomer's requirement, two sets of rudder mechanism, can be used together or separately. One of which fails to work, can be used separated to ensure normal work of steering control. It is widely used for ships with high safety performance such as large ship, oil tanker, liquefied-gas carrier, chemical tanker and etc.
