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
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
