MARINE HYDRAULIC STEERING SYSTEMS Modern, smooth, reliable... Jastram Steering Systems are built with high quality, precision components carefully matched by design to ensure long life and exceptional performance in all operating conditions. We manufacture a full product range and offer one source responsibility for your entire steering system. CONTROLS MOTOR STARTER & ALARMS HYDRAULIC POWER UNITS HYDRAULIC STEERING GEAR The Jastram Modular System Concept Jastram has developed a modular concept to help our customers understand and maintain the component groups forming a steering system....

CONTROLS Control systems range from one simple manual hydraulic helm pump with a lockvalve to combinations that include helm pumps and electrical components such as electric wheel controllers, electric lever controllers, jog levers, an autopilot and rudder indicators. The control system can also be made up entirely of electric controllers. A Jastram Control System will include some, or all, of our Power Steering Package components. These package components include: • the electric wheel controller • the Conversion and Changeover (CCO) Block U.S. Patent 5,146,745/Cdn. Patent 2,051,294 • •...

HYDRAULIC POWER UNITS HYDRAULIC STEERING GEAR ms for all types of boats and ships Hydraulic Power Units are an integral part of a power steering system and provide the ‘muscle’ (or power ) to move the steering gear, and ultimately, the rudder, against the forces of the sea. We offer two main types of power units: non follow-up and full follow-up. The choice of the type determines the performance characteristics of the steering system. A non follow-up power unit (also called a “time dependent” power unit) generally operates either full on or full off. A Jastram full follow-up power unit...

DIGITAL STEERING CONTROL SYSTEMS power steering systems The Jastram Digital Steering Control System processes steering commands into precise signals to control the hydraulic power units - which determine the accurate and responsive movements of the steering gear, and ultimately the vessel. Excellent manoeuvering control is produced by the smooth acceleration and deceleration of the rudder through its full range of motion. The algorithm logic determining response to steering commands is unique and based on Jastram's extensive operating, servicing and manufacturing experience. Steering...

Digital Control Devices This patented hybrid hydraulic/electric unit provides full follow-up digital electric control as well as emergency manual hydraulic control. When power steering, the traditional steering wheel is turned producing a very accurate rudder command signal and the rudder follows up to the position requested by the wheel. • The DH36-1 is the standard unit and produces one output signal • The DH36-2 produces two output signals - the second signal for control redundancy, or for operation of a second steering system where independent twin steering gears are installed • When...

Mode Control Processor (MCP100) This unit receives the inputs from the control devices and indicators and sends information signals to the microprocessor in the Digital Steering Controller. It has the capacity to process two digital inputs, two analog inputs and one non follow-up input, and drive two digital and two analog rudder order indicators as well as five rudder angle indicators. • Command can be transferred between digital input devices instantaneously, without interruption • Ramping non follow-up jog control with basic backup optionally • Individual adjustment of indicators is...

Analog Control Devices These units provide non follow-up (time dependent) electric control. They generally operate either full on (as long as the lever is activated) or full off (when released). • TheJ0100-1 is the standard unit and contains one set of microswitches • The J0100-2 includes a second set of microswitches • The steering lever returns to center when released. (The rudder remains where positioned when the lever is released.) • Units have molded plastic housings with stainless steel handle hardware and are waterproof as well as corrosion resistant • Operates with 12,24 or 36 VDC...
