Abstract
A semiautomatic (1) sensorized apparatus for the execution of inspections of the railway pantograph (P) is detachably associated to a railway pantograph and allows the execution of two distinct tests in succession: i) the first one, which monitors the functional properties of the pantograph, based on the characterization of the thrust force generated by the main suspension; ii) the second, which aims to identify global and local defects, adopting the principle of inspection by means of vibration analysis.
