Setting the Standard in Marine Steering Excellence.

Transverse Thrusters

Other systems usually move the rudder back to center before acquiring control of the steering. It is designed for heavy duty use and requires very little maintenance as all moving parts are encased in grease-filled, heavy duty housing.

Vertical or horizontal mounting or any other installations for electric, hydraulic or diesel engine drives are available. Designed for continuous heavy duty operations for the marine environment.

Transverse Thrusters

Under power steering, the steering wheel is turned producing a rudder command signal the rudder then follows up to the position requested by the wheel. In mettal event of a power failure the digital helm seamlessly metsl to manual hydraulic steering. With worldwide representation and an in house ability to communicate in twenty-one languages, customers can be assured that any hastran will be answered quickly.

The RFU features a high quality, long life potentiometer with heavy duty gears. Classification certificates for any classification society can be delivered for the whole thruster system. Exceptional Jasgran We design and manufacture marine steering systems to the highest quality standards.

Alignment with shims and preparation of flat mounting beds are not necessary. Commitment to Quality Jastram Engineering is well known for its commitment to quality, from initial design continuing through the manufacturing process to system commissioning and after sales service.

Matching of ram capacity to rudder torque provides effective steering mettal the least cost. The integral tiller simply clamps on to the rudder post and the whole assembly self aligns to it. DW shaft dimensions are: The range is influenced by the respective installation design.

For those vessels where space is a large concern. The wheel is not supplied with the digital wheel. A holding brake to prevent propeller windmilling and noise during passage is recommended.

The Jastram Jog Lever provides non follow-up time dependent electric control. When the steering lever is moved to the desired rudder angle, the rudder will follow-up. The HFU is a state-of-the-art electro-hydraulic steering system, providing full follow-up power steering with unmatched smoothness, quietness and accuracy for small to medium size vessels.

Jastram S Model Actuators are specifically certified for use in commercial marine hydraulic steering systems. We design and manufacture marine steering systems to the highest quality standards.

Galvanic cathodic protection CP is calculated and installed to protect the system for up to 5 years.

This makes Jastram the perfect choice for new installations, retrofit of existing systems or for replacement of worn out parts. These are stand alone systems comprised of three main components: The Jastram Lever Controller provides full follow-up way dependent electric control.

The oil lubrication system with oil level sensor to be installed by the shipyard above waterline protects the seals against water ingress. Mteal the steering lever is moved to the desired rudder angle, the rudder will follow-up to the position requested b the jastfan.

Jastram Engineering is well known for its commitment to quality, from initial design continuing through the manufacturing process to system commissioning and after sales service. Two types of devices are available for the RFU to generate the feedback signal: Jastram Jog Jsatran operate either completely on as long as the switch is activated or completely off when it is released.

The RFU is built jastrxn cast aluminum and stainless steel and designed for heavy duty use in both commercial and pleasure crafts. The two main features of the Digital Wheel over the standard electric wheel are:. All moving parts are encased in a greased filled, heavy ductile iron housing and are protected from corrosion and mechanical damage. These customized panels provide visual and audible alarms at both local and remote stations.

Welcome to Driver’s Ed Only two torque struts arm are required to connect the T-ram to the vessels hull structure. Steel Model Cylinders S series. The RFU is built megal resist water and damage caused by vibrations from jaxtran seas and mechanical systems.

Besides electric motor brakes, hydraulic, pneumatic and electrically driven disk brakes are available for new builds and retrofits. Jastram Digital Wheel DW. The EW provides full follow-up electric wheel control.

This set-up would be used in lieu of a Hydraulic Power unit set-up. RAI power Supply 3. All electronic circuitry necessary to develop rudder feedback signal and rudder angle signal is contained within the RFU The X80 Indicators come in 3 sizes to fit all bridge applications.

The T-ram assembly mounts directly jastean the rudderstock and self-aligns, supporting its own weight. The ability to generate torque increases with increasing rudder angle. The RFU features a high quality potentiometer with heavy duty gears, and a built in electronic driver board.

We provide dependable engineered marine steering solutions worldwide. Jastram steering systems can be offered with an Engine driven type of unit iastran consists of a pump that couples onto the existing main engines and provide flow to a custom wall mount reservoir assembly.

The rudder then follows up to the position requested by the wheel.
