    摘要： An actuating oleodynamic system for pumps pumping viscous material, and in particular concrete, of the open-circuit and high-pressure type supplied by one or more hydraulic pumps, with direct, automatic-sequence driving system for the actuation of the hydraulic cylinders which displace the pistons in the liners of said pump and of the cylinders of a deviation valve through which said liners are alternately put in communication with a loading hopper and with a supply pipe. The system comprises a hydraulic valve assembly to control the displacement direction of said pistons, consisting of two hydraulic distributors, each actuated by a 5-way electrovalve to invert said direction between a pumping function and an intake function.
    The hydraulic circuit driving the hydraulic cylinders of the pump is symmetrical with respect to a plane transversal to the centreline of the two cylinders arranged side by side, in correspondence of which the hydraulic supply assembly is also arranged, resulting in a simple and quick switching of the supply from "shaft side" to "piston side" and viceversa.

    摘要： A mold with hydraulic opening and closing for the casting of concrete blocks with four diverging frustoconical elements, comprises a reinforced stationary base and three tilting forms pivoted to said base and each moved by a corresponding hydraulic jack. Three tilting covers are also provided for closing three of the four end openings between the forms, and fast screw tightening means between said forms and said covers, as well as jig locators and dowel pins for centering the various mobile parts of the mold one in respect of the other. The three hydraulic jacks controlling the movement of the tilting forms are controlled by a common hydraulic gearbox.

    摘要： System for the control and monitoring of the operation of self-propelled, articulated-boom machines, in particular concrete pumps, comprising a plurality of sensors capable of continuously detecting instant data concerning the geometric conditions of the operating attitude of the machine and the load conditions thereof, as well as a central processing unit which, on the basis of such data and of previously-stored safety parameters, continuously checks for the meeting of one or more critical conditions for machine safety, such as levelling, overturning moment, stability, resonance swinging of the articulated boom. During machine operation, when at least one of said critical conditions is approached beyond a threshold value, the central unit provides to actuate a sound and visual alarm signal and at the same time to activate automatic cycles for the gradual stop of the machine and/or for gradually moving away from said critical condition.
