A holding brake to prevent propeller windmilling and noise during passage is recommended. 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. Two types of devices are available for the RFU to generate the feedback signal: Welcome to Driver’s Ed 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.

The two main features of the Digital Wheel over the standard electric wheel are: Jastram Engineering is built on the understanding of how critical steering is to the operation of any vessel. Due to construction of the T-Ram, the clamp fitted tiller provides an integral rudder carrier bearing when the ram is supported from below.

T Ram Rapson Slide Actuators. Jastram Engineering is well known for jastfan commitment to quality, from initial design continuing through the manufacturing process to system commissioning and after sales service. The Jastram Jog Lever provides non follow-up time dependent electric control. The HFU is a state-of-the-art electro-hydraulic steering system, providing full follow-up power ajstran with unmatched smoothness, quietness and accuracy for small to medium size vessels.

Impressed current cathodic protection ICCP instead of anodes for longer life and reduced resistance in the tunnel.

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. 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.

The rudder will then follow-up to the position commanded by the movement of the wheel. The T-ram assembly mounts directly on the rudderstock and self-aligns, supporting its own weight. Jastram transverse thrusters are made from high-grade certified materials and are designed individually according to the given installation conditions.

Exceptional Performance We design and manufacture marine steering systems to the highest quality standards. 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.

Products – Wagner Engineering Ltd.

Engineering for Life At Sea Jastram Engineering is built on the understanding of how critical steering is to the operation of any vessel. These customized panels provide visual and audible alarms at both local and remote stations. We design and manufacture marine steering systems to the highest quality standards. Under emergency manual hydraulic steering the numbers of turns depends on the size of the actuators.

Transverse Thrusters

metall This set-up would be used in lieu of a Hydraulic Power unit set-up. The integral tiller simply clamps on to the rudder post and the whole assembly self aligns to it. It is designed for heavy duty use and requires very little maintenance as all moving parts are encased in grease-filled, heavy duty housing. The two main features of the Digital Wheel over the standard electric wheel are:.

Transverse Thrusters

Designed for continuous heavy duty operations for the marine environment. Setting the Standard in Marine Steering Excellence. The comfort and safety of the vessel and crew is in part dependent on how well the steering system functions.

Anti-suction tunnel AST — a second smaller tunnel installed behind the bow thruster to increase the thrust during cruising. Jastram Brass Model Cylinders B series.

When the steering lever is moved to the desired rudder angle, the rudder will follow-up to the position requested b the lever. To improve performance the propeller design is continuously modified according to the latest developments.

Jastram Digital Wheel DW. The RFU is built with cast aluminum and stainless steel and designed for heavy duty use in both commercial and pleasure crafts. In essence, they start and stop the electric motor which drives the hydraulic pump powering the steering gear.

For those vessels where space is a large concern. Jastram Jog Levers operate either completely on as long as the switch is activated or completely off when it is released. Rudder Feedback Unit 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. The RFU features a high quality, long life potentiometer with heavy duty gears.

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. Classification certificates for any classification society can be delivered for the whole thruster system. In the event of a power failure the digital helm seamlessly transfers to manual hydraulic steering.

We provide dependable engineered marine steering solutions worldwide. Up to five indicators can be used with a mixture of forward and reverse scale meters.

Our line of products ranges from simple manual steering for small vessels, to digitally-controlled and integrated systems for large ships. Jastram T-Ram Steering Systems are exceptionally tough and reliable. The propeller is mounted with a tight oil press fit which allows rapid mounting and dismounting during shaft seal changes. For Supertankers Supertankers and cruise ships have maritime pilots who act as valets for the giant vessels in ports Vertical or horizontal mounting or any other installations for electric, hydraulic or diesel engine drives are available.

The oil lubrication system with oil level sensor to be installed by the shipyard above waterline protects the seals against water ingress.

We design and built according to all major marine classification rules and requirements. Jastram are specialised in fixed pitch propeller FPP thrusters which require minimal servicing due to their solidity and durability.
