Jefa WP400 cable steering pedestals

Jefa 400 series steering pedestal concept

With the 400 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 even the largest radar instruments. The integrated powerful and progressive friction brake can be operated without putting one's hand through the wheel

The 400 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 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 400 series pedestal is available as WP400 for wire steering, as RP400 for rack and pinion steering, as H400 for hydraulic steering and as TS400 for transmission steering and all pedestals are CE approved.

Jefa WP400 cable steering pedestals

The WP400 is the cable steering version of the 400 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 WP400 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 WP400 pedestal can be used for conduit cable systems by fitting the WP conduit plate underneath the pedestal.
