| Jefa 300 series steering pedestal concept |
|
With the 300 series pedestal Jefa Steering introduces a
new style integrated pedestal design. All major functions for the modern
helmsman are integrated in one central steering and control centre: The
integrated engine control offers easy installation and quick access. The
integrated compass offers easy and clear readings without the need of a separate
binnacle. The 25 mm diameter stainless steel 316 guardrail is firmly
attached to the pedestal head offering the best protection
for the compass and pedestal combined with a strong support when moving
around in the cockpit. The large glass fibre pedestal head accepts
multiple instruments and control buttons. The integrated powerful and
progressive friction brake can be operated without putting one's hand through
the wheel.
The 300 series pedestal concept has big
advantages over existing similar concepts:
- The robust
powder coated aluminium base has no mounting
holes for pedestal bolts as these are
integrated in the pedestal deck flange. This
avoids multiple weak points for damage with
the accompanying corrosion and possible
leaking.
- The input
socket has a large water draining groove
behind the cover plate to prevent any water
entering the pedestal.
- The pedestal
head largely overhangs the aluminium base to
prevent any splash water entering the
pedestal from underneath the head.
- The pedestal
head is strongly attached to the aluminium
base by resting on a horizontal flange and
clamped by a counter flange.
- The engine
control mechanism is not attached to the
pedestal head but to the pedestal base. This
offers the unique advantage of mounting the
complete mechanism to the pedestal and the
attachment of the control cables
independently from the pedestal head. The
pedestal head can be worked on separately in
the workshop to be adapted to the customer
requirements with instruments, buttons and
joysticks. This concept also eases the
retrofit of a mechanism, or a swap from
starboard to port.
- The robust
guardrail has a four point connection to the
pedestal head, spreading the loads smoothly
over the pedestal head.
- The
guardrail is attached to the back of the
pedestal leaving the top surfaces completely
usable for instruments, buttons or
joysticks.
- The
underside of the pedestal deck flange has
two large milled grooves with twin foam
gaskets for easy mounting without any
additional sealant.
- The steering
shaft is sealed by the Jefa developed PUR
seal. Normal industry seals use steel
reinforcement rings in the rubber housing.
As the standard industry rubber will start
to crack due to the UV in the sunlight, the
steel rings will corrode and destroy the
seal letting water in the steering shaft
bearings with disastrous effects.
The 300 series pedestal is available as WP300 for wire steering, as
RP300
for rack and pinion steering, as H300 for hydraulic steering and as TS300 for transmission steering and all pedestals are CE approved.

| Jefa WP300 cable steering pedestals |
The WP300 is the cable steering version of the 300 series
pedestal. The 25 mm steering shaft is equipped with the standard
international 1" taper to fit all Jefa wheels up to 1500 mm
diameter. The steering shaft has 2 ball bearings at the front of the
pedestal and one ball bearing at the aft side of the pedestal. The pedestal can be equipped with multiple sprockets to match the turns starboard
to port as specified. Please look at the table
for choosing the the sprocket size in relation to the quadrant radius. The WP300 pedestal can be used for open wire systems with our
cross
wire and parallel wire idlers. These idlers have large base plates
for a a firm clamping of the deck between the deck flange of the
pedestal and the base plate. The idlers are mounted with pedestal
mounting studs, so no additional mounting bolts are necessary. The WP300 pedestal can be used for conduit cable systems by fitting the
WP300 conduit plate underneath the pedestal. |

- The standard heights of the pedestal are 630, 710 and 800 mm.
Custom heights are available at request.
- The compass mounting flange should not exceed 180 mm diameter.
- The appropriate compass hole will be drilled when the compass is
ordered together with the pedestal.
- The pedestal mounting studs are available in multiple lengths to
suit the cockpit floor thickness. The mounting studs are positioned
on a square of 220 by 180 mm.
- The cable offset relative to the middle of the pedestal is 24 mm.
