THE KEEL SERVANT (It. Patent) 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 stem, driven by an electromechanical screw jack that works inside a jacket that is inserted and secured in the fix fin of the keel.
According to specific needs, the stem and jacket section can be rectangular or tubular, and the fix fin can be made in HR stainless steel or in cast iron.
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 in the bulb itself during melting.
A fiberglass shell is screwed to the bulb and fits like a sleeve with the fix fin to form the aerodynamic 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
