A self-propelled, articulated-boom machine comprising: - lorry-mounted concrete pumps mounted on a carriage and having an articulated boom, - extendable stabiliser legs provided in order to transfer the resting points to a certain distance from the carriage, and - a system for the control and monitoring of the operation of the self-propelled, articulated-boom machine, the system comprising: - a plurality of sensors capable of detecting instant data concerning the geometric attitude of the moving components of the machine and the load and operation data of the same, - as well as a central processing unit capable of continuously receiving such data to process them and compare them with previously stored safety parameters, wherein said central unit is capable to continuously check for the meeting of one or more critical conditions for machine safety and, when at least one of said critical conditions exceeds a predefined threshold value that can be set individually for each critical condition, the central unit is capable to actuate an alarm signal and simultaneously activate automatic cycles for stopping the machine and/or moving away from said critical condition, characterized in that said critical conditions comprise at least - the contact with the ground and levelling of said carriage, and - the overturning moment applied to said carriage by the articulated boom, wherein the system is configured - to give consent to machine operation only when at least said two conditions are below said individually preset threshold values, and - to inhibit the completion of the process in case at least one of said two conditions exceeds said individually preset threshold values until said two conditions are newly met, and - wherein the central unit of the control and monitoring system is capable of determining the admissible operation range of the lorry-mounted pump, and in particular of the articulated boom of the same, independently for each of the critical conditions detected above, whereby it is possible to set threshold parameters or a threshold function as well as a maximum approaching percentage to such threshold, beyond which the control system actuates the alarm signals and simultaneously activates automatic cycles for stopping the machine and/or moving away from said critical condition; - and wherein said central unit is provided with a self-teaching system for storing a sequence of boom movement operations in a self-teaching step manually set by the operator and for repeating it on demand, such that, when repeating the sequence, the system operates intelligently "a priori" avoiding to exceed the threshold of the critical conditions that may have been encountered during the self-teaching step, hence suggesting a correct boom trajectory for the required process. - lorry-mounted concrete pumps mounted on a carriage and having an articulated boom, - extendable stabiliser legs provided in order to transfer the resting points to a certain distance from the carriage, and - a system for the control and monitoring of the operation of the self-propelled, articulated-boom machine, - a plurality of sensors capable of detecting instant data concerning the geometric attitude of the moving components of the machine and the load and operation data of the same, - as well as a central processing unit capable of continuously receiving such data to process them and compare them with previously stored safety parameters, wherein said central unit is capable to continuously check for the meeting of one or more critical conditions for machine safety and, when at least one of said critical conditions exceeds a predefined threshold value that can be set individually for each critical condition, the central unit is capable to actuate an alarm signal and simultaneously activate automatic cycles for stopping the machine and/or moving away from said critical condition, - the contact with the ground and levelling of said carriage, and - the overturning moment applied to said carriage by the articulated boom, - to give consent to machine operation only when at least said two conditions are below said individually preset threshold values, and - to inhibit the completion of the process in case at least one of said two conditions exceeds said individually preset threshold values until said two conditions are newly met, and - wherein the central unit of the control and monitoring system is capable of determining the admissible operation range of the lorry-mounted pump, and in particular of the articulated boom of the same, independently for each of the critical conditions detected above, whereby it is possible to set threshold parameters or a threshold function as well as a maximum approaching percentage to such threshold, beyond which the control system actuates the alarm signals and simultaneously activates automatic cycles for stopping the machine and/or moving away from said critical condition;
