Principal Power steering system consists of a cylinder, a pump and handle. The oil is pressured from hydraulic pump and a handle(orbitrol) control a cylinder. The cylinder helps rudder move and the required oil is supplied from the hydraulic pump. Cylinder is classified Single, Rotary, Twin, Two rudders by torque and appearance Pump is classified Pulley type drived by engine and Power unit drived by electric motor We offer 7 kinds of handles with various appearance and functions. Features Narrow handle diameter helps you operate with small energy and power steering system offers light operation On where you put the handle, the rudder is fixed Structure that the rudder does not rotate even when the tide power the rudder When engine stops, manual steering is capable (Handle becomes heavy) You can choose the combination fit to your vessel Application Vessel above 350 HP A wide range of vessel from fishing boat to ferry
Principle Electric steering system is equl with the power steering system equipped a solenoid valve. It is the system which steers with solenoid valve by comparing resistance values of electric handle and rudder angle sensor It consists of a cylinder and a pump, an solenoid valve and a electric handle. The cylinder makes the rudder move and the pump supplies the oil to the cylinder. Handle is to swap the direction of hydraulic pressure Cylinder is classified Single, Rotary, Twin, Two rudders by torque and appearance Pump is classified Pulley type drived by engine and Power unit drived by electric motor We offer 7 kinds of handles with various appearance and functions. You can choose the combination fit to your vessel Key features Narrow handle diameter helps you operate with small energy and power steering system offers light operation The number of rotation wheel is 2.8 like the hydraulic handle Analogue type of a indicator for handle and a rudder angle indicator are applied. Controlled by Joystick / Autopilot USB port Autopilot can be used together. Application Vessel above 350HP A wide range of vessel from fishing boat to ferry
