When the steering lever is moved to the desired rudder angle, the rudder will follow-up to the position requested b the lever. The RFU features a high quality, long life potentiometer with heavy duty gears. We design and manufacture marine steering systems to the highest quality standards.

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 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.

Welcome to Driver’s Ed Other systems usually move the rudder back to center before acquiring control of the steering. A holding brake to prevent propeller windmilling and noise during passage is recommended.

The integral tiller simply clamps on to the rudder uastran and the whole assembly self aligns to it. Anti-suction tunnel AST — a second smaller tunnel installed behind the bow thruster to increase the thrust during cruising. The Jastram Jog Lever provides non follow-up time dependent electric control.

Setting the Standard in Marine Steering Excellence.

Impressed current cathodic protection ICCP instead of anodes for longer life and reduced resistance ajstran the tunnel. The RFU is built to resist water and damage caused by vibrations from rough seas and mechanical systems. Supertankers and cruise ships have maritime pilots who act as valets for the giant vessels in ports T Ram Rapson Slide Actuators.

In essence, they start and stop the electric motor which drives the hydraulic pump powering the steering gear. 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. RAI power Supply 3. Steel Model Cylinders S series. Jastram transverse thrusters are nastran from high-grade certified metl and are designed individually according to the given installation conditions.

The two main features of the Digital Wheel over the standard electric wheel are: The ability to generate torque increases with increasing rudder angle. With electric drive systems ranging from the low-cost 3-step control for onshore manoeuvring to the frequency-controlled drive for offshore dynamic positioning Jastram offer transverse thrusters for a wide variety of vessel types.

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

Transverse Thrusters

Jastram B Model Actuators are double-acting equal displacement cylinders which are directly connected to a tiller.

Jastram S Model Actuators are specifically certified for use in commercial marine hydraulic steering systems. The Largest of the Indicators is the overhead three faced panoramic indicator. When the steering lever is moved to the desired rudder angle, the rudder will follow-up. To improve performance the propeller design is continuously modified according to the latest developments.

Jastram T-Ram Steering Systems are exceptionally tough and reliable. Due to construction of the T-Ram, the clamp fitted tiller provides an integral rudder carrier bearing when the ram is supported from below.

Transverse Thrusters

Engineering for Life At Sea Jastram Engineering is built on the understanding of how critical steering is to the operation of any vessel. When the traditional steering wheel is turned the EW produces an analog rudder command signal. The Digital Helm Manifold DHM is a small, compact manifold which provides iastran transfer from fly-by-wire steering to emergency manual hydraulic steering in the event of a power failure.

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. jasfran

Jasrtan electronic circuitry necessary to develop rudder feedback signal and rudder angle signal is contained within the RFU Jastram Engineering is built on the understanding of how critical steering is to the operation of any vessel.

This makes Jastram the perfect choice for new installations, retrofit of existing systems or for replacement of worn out parts. 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.

For Supertankers Supertankers meetal cruise ships have maritime metzl who act as valets for the giant vessels in ports The range is influenced by the respective installation design.

We design and built according to all major marine classification rules and requirements. Commitment to Quality Jastram Engineering is jxstran known for its commitment to quality, from initial design continuing through the manufacturing process to system commissioning and after sales service.

Jastram are specialised in fixed pitch propeller FPP thrusters which require minimal servicing due to their solidity and durability.
