Anti-suction tunnel AST — a second smaller tunnel installed behind the bow thruster to increase the thrust during cruising.

Due to construction of the T-Ram, the clamp fitted tiller provides an integral rudder carrier bearing when the ram is supported from below. These are stand alone systems comprised of three main components: Alignment with shims and preparation of flat mounting beds are not necessary. Galvanic cathodic protection CP is calculated and installed to protect the system for up to 5 years. Besides electric motor brakes, hydraulic, pneumatic and electrically driven disk brakes are available for new builds and retrofits.

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 RFU features a high quality potentiometer netal heavy duty gears, and a built in electronic driver board. The rudder will then follow-up to the position commanded by the movement of the wheel. 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.

Transverse Thrusters

The X80 Indicators come in 3 sizes to fit all bridge applications. This motivating force is why Jastram is compelled to design and manufacture to the highest quality. We design and built according to all major marine classification rules and requirements. Vertical or horizontal mounting or any other installations for electric, hydraulic or diesel engine drives are available. Only jastan torque struts arm are required to connect the T-ram to the vessels hull structure.

The rudder then follows up to the position requested by the wheel. When taking over control of the steering system the Digital wheel takes over at the present position of the rudder. Our line of products ranges from simple manual steering for small vessels, to digitally-controlled and integrated systems for large ships.

Powerunits are available to meet specific design challenges or requirements of the vessel owner, naval jaztran or shipyard. The two main features of the Digital Wheel over the standard electric wheel are: The EW provides full follow-up electric wheel control.

Jastram have been developing and producing transverse thrusters since Jastram are specialised in fixed pitch propeller FPP thrusters which require minimal servicing due to their solidity and durability. Under power steering, the steering wheel is turned producing a metql command signal the rudder then follows up to the position requested by the wheel.

Jastram Engineering is built on the understanding of how critical steering is to the operation of any vessel. Under power steering, the steering wheel is turned producing a rudder command signal.

Rudder Feedback Unit Jastan 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. All moving parts are encased in a greased filled, heavy ductile iron housing and are protected from corrosion and mechanical damage.

This makes Jastram the perfect choice for new installations, retrofit of existing systems or for replacement of worn out parts. When the steering lever is moved to the desired rudder angle, the rudder will follow-up.

Up to five indicators can be used with a mixture jastrah forward and reverse scale meters. In the event of a power failure the digital helm seamlessly transfers to manual hydraulic steering.

Engineering for Life At Sea Jastram Engineering is built on the understanding of how critical steering is to the operation of any vessel.

The ability to generate torque increases with increasing rudder angle. Digital Wheels are unique input devices which provide full follow-up digital electric control.

The stainless steel ring in the propeller tip region jaetran the tunnel against cavitation damage. Jastram S Model Actuators are specifically certified for use in commercial marine hydraulic steering systems.

The Jastram Jog Lever provides non follow-up time dependent electric control. The wheel is not supplied with the digital wheel. T Ram Rapson Slide Actuators.

Welcome to Driver’s Ed Matching of ram capacity to rudder torque provides effective steering at the least cost. Jastram steering systems can be offered with an Engine driven type of jaxtran which consists of a pump that couples onto the existing main engines and provide flow to a custom wall mount reservoir assembly.

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 The comfort and safety of the vessel and crew is in part dependent on how well the steering system functions.

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 meet customer requirements.

The RFU is built with cast aluminum and stainless steel and designed for heavy duty use in both commercial and pleasure crafts. Supertankers and cruise ships have maritime pilots who act as valets for the giant vessels in ports In essence, they start and stop the electric motor which drives the hydraulic pump powering the steering gear.

DW shaft dimensions are: When the steering lever is moved to the desired rudder angle, the rudder will follow-up to the position metwl b the lever. Designed for continuous heavy duty operations for the marine environment. They provide a proven, trouble free system for all types of commercial vessels.
