Jog Lever NFU

Stuurhendel Non Follow Up

The Jastram Jog Lever provides non follow-up (time dependent) electric control.

Jastram Jog Levers operate either completely on (as long as the switch is activated) or completely off (when it is released).

Lever Controllers FFU


The Jastram Lever Controller provides full follow-up (way dependent) electric control.

When the steering lever is moved to the desired rudder angle, the rudder will follow-up to the position requested b the lever.

Electrical Wheel FFU


The EW provides full follow-up electric wheel control.  When the traditional steering wheel is turned the EW produces an analog rudder command signal.  The rudder will then follow-up to the position commanded by the movement of the wheel.

Digital Wheel


Digital Wheels are unique input devices which provide full follow-up digital electric control.  The two main features of the Digital Wheel over the standard electric wheel are:

1. A programmable number of wheel turns from ¼ to 10 turns lock to lock.

2. When taking over control of the steering system the Digital wheel takes over at the present position of the rudder.

Digital Helm/Manual


This patented hybrid hydraulic / electric unit provides full follow-up digital electric control as well as emergency manual hydraulic control. 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.  In the event of a power failure the digital helm seamlessly transfers to manual hydraulic steering. Under emergency manual hydraulic steering the numbers of turns depends on the size of the actuators.

Digital Helm Manifold


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.

Rudder feedback Unit


The RFU 300/400 is built to resist water and damage caused by vibrations from rough seas and mechanical systems. The RFU 300/400 features a high quality, long life potentiometer with heavy duty gears.

Rudder feedback stainless


The RFU 2000 is built with cast aluminum and stainless steel and designed for heavy duty use in both commercial and pleasure crafts.  Two types of devices are available for the RFU 2000 to generate the feedback signal:  the standard is the potentiometer type, and second would be the optional contact free Hall Effect.

Hydraulic follow-up

Hydraulisch follow up stuursysteem

The HFU360 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.

Rudder indicator

Roerstand meter

The X80 Series Rudder Angle Indicators are produced to fill the requests of Vessel operators and to meet Classification Societies requirements.  The X80 Indicators come in 3 sizes to fit all bridge applications.  Up to five indicators can be used with a mixture of forward and reverse scale meters.
