The invention relates to a pantograph test device for pantograph net contact pressure and hard point detection. The pantograph test device comprises a supporting assembly, a weight assembly, a pantograph sliding plate assembly, a guide roller assembly and a steel wire rope assembly. The weight assembly and the guide roller assembly are connected through the steel wire rope assembly and are hung on the supporting assembly; the pantograph slide plate assembly is connected with the guide pulley assembly and is hung on the supporting assembly by means of the guide pulley assembly; the weight assembly and the pantograph slide plate assembly can achieve gravity balance at the two ends on the supporting assembly through the steel wire rope assembly; when the pantograph slide plate assembly is pressed by a contact line, the pantograph slide plate assembly can fall together with the guide roller assembly and drive the weight assembly to rise. According to the pantograph test device provided by the invention, the panto
