Jastram Jog Levers operate either completely on as long as the switch is activated or completely off when it is metzl. 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 Largest of the Indicators is the overhead three faced panoramic indicator.

The rudder will then follow-up to the position commanded by the movement of the wheel. Setting the Standard in Marine Steering Excellence. The Digital Helm Manifold DHM is a small, compact manifold which provides seamless transfer from fly-by-wire steering to emergency manual hydraulic steering in the event of a power failure.

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

In essence, they start and stop the electric motor which drives the hydraulic pump powering the steering gear. Up to five indicators can be used with a mixture of forward and reverse scale meters.


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

The two main features of the Digital Wheel over the standard electric wheel are: The T-ram is a complete self-enclosed jaxtran unit that provides fast rudder movement through midships and maximum torque at the hadvover positions.

They provide a proven, trouble free system for all types of commercial vessels. The MSA comes in 3 series: In the event of a power failure the digital helm seamlessly transfers to manual hydraulic steering.

The comfort and safety of the vessel and crew is in part dependent on how well the steering system functions. Under emergency manual hydraulic steering the numbers of turns depends on the size of the actuators. DW shaft dimensions are: Digital Wheels are unique input devices which provide full follow-up digital electric control.

Jastram Digital Wheel DW.

Supertankers and cruise ships have maritime jasrran who act as valets for the giant vessels in ports 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 Jastram Jog Lever provides non follow-up time dependent electric control.


We provide dependable engineered marine steering solutions worldwide. All electronic circuitry necessary to develop rudder feedback signal and rudder angle signal is contained within the RFU The Jastram Lever Controller provides full follow-up way dependent electric control.

RAI power Supply 3. The two main features of the Digital Wheel over the standard electric wheel are:.

Products – Wagner Engineering Ltd.

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

This set-up would be used in lieu of a Hydraulic Power unit set-up. Only two torque struts arm are required to connect the T-ram to the vessels hull structure.

Transverse Thrusters

Matching of ram capacity to rudder torque provides effective steering at the least cost. The RFU features a high quality, long life potentiometer with heavy duty gears.

Galvanic cathodic protection CP is jasttan and installed to protect the system for up to 5 years. The stainless steel ring in the propeller tip region protects the tunnel against cavitation damage.
