Abstract: 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.

Abstract: A movable pump for concrete comprises a vehicle provided with a frame (16) to which a fifth wheel (15) is fixed that is suitable for supporting a distributing arm (40) for distributing concrete, mounted rotatably thereupon, there being present a pair of front legs (17, 18) and a pair of rear legs (19, 20) for stabilising the pump that are movable between an operative position extending from the vehicle and a retracted non-operative position, the front legs being telescopic and diagonally extendible forward on opposite sides of the vehicle and each having a fixed part that is integral with said frame (16), the rear supporting legs being rotatable hinged on said frame (16) on opposite sides of the vehicle. The fixed parts of the telescopic legs are arranged near the fifth wheel (15) and the rear legs (19, 20) are hinged on the frame with hinge (21, 22) near said fifth wheel (15).

Abstract: The invention concerns a concrete pump, of the type comprising a pair of pumping cylinders alternatively operating under the control of a backflow hydraulic pump - to draw concrete from a hopper and feed it, by way of a rocking valve (S-valve), into the transport and delivery duct - wherein said cylinders are provided with stops to control the advance of the starting movements of the S-valve and wherein the motion of the pistons in the cylinders is reversed in respect of the moment in which said pistons reach the top dead center. According to the invention, said stops are located in the position for the most efficient working with the highest number of pumping cycles per minute, and electronic means are provided to set said advance time, by delaying the starting movement of the S-valve and the reversal of the backflow hydraulic pump according to the actual number of pumping cycles per minute.
