Product

Jastram designs and manufactures a whole line of steering gears and steering controls, including ram type gears (Model B and Model S) and rapson slide gears (Model K).  A complete range of steering controls including electric helm, full follow-up levers, jog levers, rudder angle indicators and various steering control amplifiers ensures that Jastram can offer complete system responsibility for any steering application

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 independent steering system, due to the inherently safe redundancy of two steering gears.  High speed catamarans and Swath vessels use independent rudder system, because such arrangement saves weight and allow for 'toe-in' and 'toe-out' after installation onboard.

Jastram supplies special steering cylinders and helm pumps for various jet drives, enabling the operator to manually control larger water jets form several steering positions.
