Product

Jastram designs and manufactures, a whole line of marine steering gears and steering controls, including ram type gears ( Model B & Model S ABS Equipment Type Approval - B with CE certification ) and rapson slide gears ( Model K ).  A complete range of steering controls including:  independent steering control systems, electric helm, full follow-up levers, jog levers, rudder angle indicators and various steering control amplifiers - ensure that Jastram can offer complete system responsibility for any marine steering application.

Jastram produces several lines of marine hydraulic steering gears in complete ranges, as well as steering controls, power units and motor starters, ensuring overall system responsibility for all types of recreational & mega yachts, commercial vessels and offshore patrol vessels. Also, Jastram products are designed and manufactured in accordance with all major classification society rules including: ABS, BV, CE, CCG, CR, DNV, GL, KRS, LR, NKK, USCG and ZC. Their quality assurance program includes ISO 9000 objectives and a commitment to constant improvement.

Applications

Jastram specializes in custom applications, where close co-operation with the naval architect ensures that the optimal steering system is developed in each application.  In combination with our patented CCO system, Jastram can provide a proportional steering system, in which rudder movements are accelerated and decelerated, resulting in shockless and noiseless operation of the steering rams.  If power is lost to the steering gear, this system automatically reverts to emergency manual mode.

Jastram also provides steering systems with independent, not mechanically linked, twin rudder arrangements.  Modern icebreakers use an independent steering system, due to the inherently safe redundancy of two steering gears. 

High speed catamarans and Swath vessels use an independent rudder system, because such arrangements save weight and allows for 'toe-in' and 'toe-out' after installation onboard.

Cost Savings

Jastram's approach to modular system components can save substantial costs for a shipyard. All shipboard wiring required to connect the various steering components (amplifier, rudder transmitter, rudder angle indicator, etc.) can be supplied by Jastram, cables pre-cut to length and with plug-in connectors installed at both cable ends. All that remains to be done by the shipyards is to run the cables and plug the connectors into the receptacles of the component. Expensive labor and set-up time are reduced to a minimum, not to mention trouble shooting. Prewired cable trees and the various steering components are shop tested and calibrated, and are ready for final installation plug-in.

Computer software

Jastram has developed a computer program, which is menu driven and allows almost instant torque calculation and gear selection upon answering some simple questions.  Naval architects and shipyards throughout the world make use of this program by simply advising the basic specifications for the steering system and receiving a full technical quotation usually within a few days.

Jastram has available an AutoCad library of all its modular components including steering gears and accessories.  This software package enables naval architects and designers to 'import' complete steering system layouts into their design at an early stage, significantly reducing drawing time and achieving accurate up to date designs at substantial cost savings.  This design software is available free of charge.
