THE KEEL SERVANT IS AN INNOVATIVE LIFTING SYSTEM FOR TELESCOPIC KEELS.
The mechanism is suitable for a wide range of sizes for telescopic keel systems, consisting of a fixed fin and a lifting bulb.
The lifting mechanism is made up of a shaft with a rectangular section, driven by an electromechanical screw jack that works inside a jacket that is inserted and secured in the fix fin of the keel.
The mechanism is mounted on a fixed fin that must be designed with a special rectangular cross-section space in order to receive the jacket (fixed) of the mechanism.
The bulb is connected by a pair of flanges, one of which is integral with the shaft (sliding) of the mechanism and the other is inserted by melting in the bulb itself.
A fiberglass shell is screwed to the bulb and fits like a sleeve with the fix fin to form the hydrodynamic profile around the sliding part.
The materials of all parts are carefully selected for sea water heavy duty conditions:
• Jack and screw:
· · stainless steel AISI 316 grade
• Travelling plate and nut, sleevs, pads, stoppers:
· · bronze EN 2.0980
• Shaft, jacket, flanges:
· · stainless steel AISI 304 grade
