Abstract

La présente invention concerne un ensemble tête de trépied (1), comprenant un moteur (3) et un premier bras d'arbre (2) ; ledit moteur (3) entraîne ledit premier bras d'arbre (2) en rotation ; ledit ensemble tête de trépied (1) comprend également un élément de limitation de position ; ledit élément de limitation de position est pourvu d'une partie de limitation de position ; l'élément de limitation de position est relié entre le moteur (3) et le premier bras d'arbre (2) ; l'élément de limitation de position peut tourner dans une première plage prédéfinie d'angles entre la partie de limitation de position et le premier bras d'arbre (2) ; l'élément de limitation de position peut tourner dans une seconde plage prédéfinie d'angles entre la partie de limitation de position et le moteur (3). L'ensemble tête de trépied peut limiter l'angle de rotation entre le premier bras d'arbre et le moteur, empêchant ainsi la situation dans laquelle se produit un enroulement voire une rupture du câble électrique reliant le premier bras d'arbre et le moteur du fait d'un angle de rotation excessivement grand de la tête de trépied.
