Abstract: A crane machine with articulated arm allows a greater operating flexibility upon operating the distal end of the articulated arm and in particular the arm inverse operation and it comprises a base frame, having a supporting base for an articulated arm which in turn comprises: a first section of articulated arm, revolvingly connected to said supporting base at a first proximal end thereof; a second intermediate section of articulated arm, revolvingly connected to a first distal end of said first section at a second proximal end thereof; a third section of articulated arm, revolvingly connected to a second distal end of said second section at a third proximal end thereof, comprising, on a third distal end thereof, an attachment for a platform, a basket, a hooking or any working device apt to be operated by means of said articulated arm; and actuating means, controlled by a control system, respectively connected to said supporting base and to each one of said sections of articulated arm, for actuating and rotati
