Abstract

LA TECHNIQUE DE CETTE DECOUVERTE EST BASEE SUR UN DISPOSITIF METALLIQUE TRIANGULAIRE FIXE AUX EXTREMITES DES DENTS DU GRAPPIN AFIN DE LES MAINTENIR A UNE DISTANCE PREDETERMINEE A LA SURFACE DU SOL. QUAND LE MECANISME POUR LA FERMETURE DU GRAPPIN EST DECLENCHE, LES PIERRES GROSSES OU PETITES SE TROUVANT SOUS LES CANNES EN VOIE DE CHARGEMENT NE SE RAMASSENT POINT AVEC LES CANNES CAR LES EXTREMITES DU GRAPPIN GLISSENT SUR LES PIERRES. DE PLUS, LES DENTS DU GRAPPIN NE S'ENFONCENT PAS DANS LA TERRE. A MESURE QUE LES DENTS SERRENT LES CANNES, LES EXTREMITES SE LEVENT TOUT EN EVITANT DE CHARGER LES PIERRES AVEC LES CANNES.
