Ship steering system JumboZ-500

electro-hydraulic

Model : JumboZ-500 is planned for medium and heavy in-board vessels like 1.Heavy Fishing Vessels -100 to 130 feet 2.Medium barges 3.High speed passenger vessels TECHNICAL SPECIFICATION Specification - JumboZ-500 Hydraulic Actuator Ram Size(mm) - 40X2 Nos Hydraulic Actuator Thrust (Kgf)) - 1400@ 50kg/cm2 Hydraulic Actuator Torque with Tiller Arm of 300mm (kg.m) - 500 Hydraulic Actuator Stroke(mm) - 440 Tiller Arm Type - Double Ended Tiller Arm Turn - Upto45 ° both sides Steering System - Steering Wheel/Joy Stick Emergency Manual Steering - Built-in Low Pressure Alarm - Optional Temperature Alarm - Optional Port/Starboard End Alarm - Optional Rudder Position Indicator - Optional Electro/Engine Driven Hydraulic Powerpack In Electro/Engine drive system, an Electric Motor driven / Engine Driven Powerpack, is providing the pressurised oil to the system. Hydraulic pump is coupled to a shaft, driven by Engine/Electric Motor This type of Electro-Hydraulic Powerpack Driven by Electric Motor, are used in Heavy Barges and Mini Ships, where Generators are used to power the steering system Photograph below shows a typical Engine Driven Powerpack fitted in a fishing vessel, with sea-water cooled oil cooler. Pair of Semi-Balanced Hydraulic Steering Actuators A Pair of Semi-Balanced Hydraulic Linear Actuators are planned, to turn the tiller-arm to both sides of the vessel, smoothly and precisely. Oil supply ports are provided on both sides of the these actuators, through which ,oil can be supplied to the pistons of the actuators. As pressurised oil is supplied from Helm pump to the Linear Acuator, the piston-rod will move forward or backward depending on to which supply port
