320-1000kN m Ram type Marine Electro-hydraulic Steering Gear
320-1000kN m ram type electro-hydraulic steering gear is four cylinders with twin piston and one tiller type. The reciprocating and ram type marine electro-hydraulic steering gear series consist of two sets of reciprocating and ram type rudder mechanism, two sets of motor kinetic tank for oil pump, one reserve tank. Their control mode, including electronic control and pump control, can be used together with any form of autopilot or follow-up pilot. To meet cunstomer's requirements, two sets of rudder mechanism can be used together or separately. If one fails to work, it can be used separated to ensure normal work of steering control. Marine ram type electro-hydraulic steering gear is widely used for ships with high safety performance such as large ship, oil tanker, liquefied-gas carrier, chemical tanker and etc.
