We design and manufacture marine steering systems to the highest quality standards. Up to five indicators can be used with a mixture of forward and reverse jastrxn meters.

Classification certificates for any classification society can be delivered for the whole thruster system. 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.

They provide a proven, trouble free system for all types of commercial vessels.

Jastram T-Ram Steering Systems are exceptionally tough and reliable. The RFU features a high quality, long life potentiometer with heavy duty gears. Alignment with shims and preparation of flat mounting metql are not necessary. A holding brake to prevent propeller windmilling and noise during passage is recommended.

Under emergency manual hydraulic steering the numbers of turns depends on the size of the actuators. Reliable gears, worldwide service, direct contact to our service department and detailed archived data for each delivered system are well accepted by the maritime industry and international shipping companies.

Transverse Thrusters

The RFU outputs both a rudder angle indicator signal and rudder feedback signal, as well as an optional second jastrann second rudder angle indicator signal.

The Jasttan comes in 3 series: Besides electric motor brakes, hydraulic, pneumatic ketal electrically driven disk brakes are available for new builds and retrofits. We provide dependable engineered marine steering solutions worldwide. Matching of ram capacity to rudder torque provides effective steering at the least cost. Setting the Standard in Marine Steering Excellence. Impressed current cathodic protection ICCP jashran of anodes for longer life and reduced resistance in the tunnel.

The T-ram is a complete self-enclosed steering unit that provides fast rudder movement through midships and maximum torque at the hadvover positions. The propeller is mounted with a tight oil press fit which allows rapid mounting and dismounting during shaft seal changes. The given thrust range in kN results from the calculation using the column ‘Max kW’ and is based on optimised tunnel, inlet cone and fore shapes.

The T-ram assembly mounts directly on the rudderstock and self-aligns, supporting its own weight.

Jastram have been developing and producing transverse thrusters since In essence, they start and stop the electric motor which drives the hydraulic pump powering the steering gear. Jastram steering systems can be offered with an Engine driven type of unit which consists of a pump that couples onto the existing main engines and provide flow to a custom wall mount reservoir assembly.

The rudder will then follow-up to the position commanded by the movement of the wheel. To improve performance the propeller design is continuously modified according to the latest developments.

Drive shaft extensions for restricted space in stern installations and detachable systems for workboats to allow servicing without docking are examples of our ability to jasrran customer requirements.

The two main features of the Digital Wheel over the standard electric wheel are: Jastram S Model Actuators are specifically certified for use in commercial marine hydraulic steering systems.

The oil lubrication system with oil level sensor to be installed by the shipyard above waterline protects the seals against water ingress. RAI power Supply 3. This makes Jastrann the perfect choice for new installations, retrofit of existing systems or for replacement of worn out parts.

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. This set-up would be used in lieu of a Hydraulic Power unit set-up.

Transverse Thrusters

When the steering lever is moved to the desired rudder angle, the rudder will follow-up to the position requested b the lever. All moving parts are encased in a greased filled, heavy ductile iron housing and are protected from corrosion and mechanical damage. Due to construction of the T-Ram, the clamp fitted tiller provides an integral rudder carrier bearing when the ram is supported from below.

The comfort and safety of the vessel and crew is in part dependent on how well the steering system functions. Two types of devices are available for the RFU to generate the feedback signal: Designed for continuous heavy duty operations for the marine environment.
