Steering
Directional control of the pedestal is achieved by turning the steering
ring mounted at the top of the column. The steering system is geared
so that the skid wheels turn by the same amount as the steering
ring. This ensures, for example, that with the pedestal set to crab,
turning the steering ring by 90° will also cause the pedestal to change
direction by 90°. The steering ring is fitted with two movable indicators
(4) which can be used to mark the straight-ahead position of the ring
and will provide a reference point when steering.
The pedestal has a crab/steer arrangement with a foot-operated
changeover mechanism, which provides a steer setting - one wheel
steering, two fixed; or a crab setting - all three wheels turning
together.
Pushing the pedal (6) operates the changeover mechanism which
toggles the pedestal between crab (3) and steer (1).
Although the pedal can be pressed with the wheels in any position,
the changeover will not occur until the wheels are all facing forward,
so the steering ring may have to be turned by up to 180° before the
changeover mechanism engages. This arrangement ensures that
the fixed wheels will always lock in the straight-ahead position when
changing from crab to steer.
