Unit cranes consist of three jointed arms (13-15), the middle arm (14) being in the form of a polygon comprising a number of units jointed together, the mobility of the units being arranged by influencing the units internally. The object of the invention is to achieve improved traction curves and speed curves, and this is effected by influencing the movement of the units from the outside by means of a hydraulic mechanism.
Généralement, les grues comprennent trois bras reliés (13-15), le bras intermédiaire (14) étant sous la forme d'un polygone comprenant un certain nombre d'éléments reliés entre eux et se déplaçant sous l'effet d'une action interne. Cette invention a pour objet d'obtenir de meilleures courbes de traction et de vitesse, ce que l'on réussit en agissant à partir de l'extérieur sur les éléments, aux fins de déplacement de ceux-ci, par le biais d'un mécanisme hydraulique.
