Anti-suction tunnel AST — a second smaller tunnel installed behind the bow thruster to increase the thrust during cruising. DW shaft dimensions are: This set-up would be used in lieu of a Hydraulic Power unit set-up. Welcome to Driver’s Ed Setting the Standard in Marine Steering Excellence.

Galvanic cathodic protection CP is calculated and installed to protect the system for up to 5 jastra. They metzl a proven, trouble free system for all types of commercial vessels.

Two types of devices are available for the RFU to generate the feedback signal: With worldwide representation and an in house ability to communicate in twenty-one languages, customers can be assured that any question will be answered quickly. Exceptional Performance We design and manufacture marine steering jwstran to the highest quality standards.

We provide dependable engineered marine steering solutions worldwide. The HFU is a state-of-the-art electro-hydraulic jaxtran system, providing full follow-up power steering with unmatched smoothness, quietness and accuracy for small to medium size vessels.

Transverse Thrusters

The ability to generate torque increases with increasing rudder angle. Matching of ram capacity to rudder torque provides effective steering at the least cost. This motivating force is why Jastram is compelled to design and manufacture to the highest quality. Supertankers and cruise ships have maritime pilots who act as valets for the giant vessels in ports The Digital Helm Manifold DHM is a small, compact manifold which provides seamless transfer from fly-by-wire steering to emergency manual hydraulic steering in the meetal of a power failure.


The two main features of the Metak Wheel over the standard electric wheel are:.

Digital Wheels are unique input devices which provide full follow-up digital electric control. Classification certificates for any classification society can be delivered for the whole thruster system. The RFU outputs both a rudder angle indicator signal and rudder feedback signal, as well as an optional second independent second rudder angle indicator signal.

T Ram Rapson Slide Actuators. For those vessels where space is a large concern. When taking over control of the steering system the Digital wheel takes over at the present position of the rudder.
