Abstract: A system for controlling and monitoring the operation of self-moving machines with an articulated arm, particularly concrete pumps, is disclosed comprising a plurality of sensors and transducers apt to collect data regarding the machine position, attitude and operating parameters, and a central unit apt to receive in real time said data, process and compare them with reference data regarding the proper use of the machine and make them comprehensible to an operator. A maintenance method based on the acquisition and comparison of the data of said system equipped with a memory device is also described.

Abstract: 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.
