Abstract

Appareil élévateur à flèche pivotante. La flèche se compose d'un secteur inférieur articulé sur un plateau de support, d'un secteur intermédiaire coulissant dans ce secteur inférieur sous la commande d'un vérin articulé sur un bras de support, et d'un secteur supérieur qu'un câble fait coulisser hors du secteur intermédiaire lorsque celui-ci prend sa position d'extension. Application aux appareils de levage dont l'extrémité de la flèche doit rester à distance sensiblement constante d'une surface verticale.Lifting device with pivoting boom. The boom consists of a lower sector articulated on a support plate, an intermediate sector sliding in this lower sector under the control of a cylinder articulated on a support arm, and an upper sector than a cable slides out of the intermediate sector when the latter takes its extended position. Application to lifting devices the end of the jib of which must remain at a substantially constant distance from a vertical surface.
