| Jefa 200 series steering pedestal concept |
With the 200 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 glass fibre pedestal head accepts 2 instruments and
multiple control buttons. The integrated powerful and
progressive friction brake can be operated without putting one's hand through
the wheel.
The 200 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 small 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 200 series pedestal is available as WP200 for wire steering, as RP200
for rack and pinion steering, as H200 for hydraulic steering and as
TS200 for transmission steering and all pedestals are CE approved.

| Jefa WP200 cable steering pedestals |
 The WP200 is the cable steering version of the 200 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 WP200 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 WP200 pedestal can be used for conduit cable systems by fitting the
WP200 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.
