    摘要： Method to make an arm for the distribution of concrete (10), or other material similar to concrete, used on heavy work vehicles (11), wherein the arm (10) comprises a plurality of segments (21-25) selectively folding and extendible one with respect to the other. Each segment (21-25) comprises a main girder and auxiliary elements for connection to adjacent segments or for attachment of movement and/or supporting devices for the pipe that carries the concrete. The method comprises a first step in which each main girder (20) is formed, with a predefined length, by depositing a plurality of layers of pre-impregnated composite material in a female type mold. The method comprises a second step in which the composite material, deposited in layers in the mold in a variable number of layers, is subjected to polymerization. The method comprises a third step in which each main girder (20) is removed from the mold and a fourth step in which the auxiliary elements are associated with each girder (20) so as to form a relative segment (21-25). The method comprises a fifth step in which the extendible arm (10) is assembled, connecting the various segments (21-25) at the respective ends. The cross section of each of the main girders (20) of the segments (21-25) is substantially constant over its whole length. The female mold consists of one or more elementary molds of equal section, connected in sequence with each other according to the overall length of the main girder (20) to be made.

    摘要： The invention relates to a concrete supply arm, to be mounted in particular on vehicle-transported concrete pumps, having several sections (11,12) and articulating joints between said sections. In this arm the relative movement of the sections (11,12) is performed, in correspondence of at least some of the articulating joints of the arm, by means of actuator mechanisms (23) consisting of a worm gear actuated by a hydraulic motor. Conveniently said actuators also comprise a locking brake.
