A crane machine with articulated arm comprises a base frame, a supporting base and an articulated arm comprising a first section revolvingly connected to said supporting base at a first proximal end thereof; a second intermediate section revolvingly connected to a first distal end of said first section at a second proximal end thereof; a third section 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 respectively connected to said supporting base and to each one of said sections of articulated arm, for actuating and rotating each one of said sections of articulated arm and a platform, a basket, a hooking or any working device apt to be operated by means of said articulated arm, wherein one or more of said sections of articulated arm are divided into two proximal and distal half-tracts revolving one with respect to the other one around the axis of the respective section of articulated arm, one proximal half-tract thereof is fixed whereas another distal half-tract is revolving, a revolving attachment member and additional actuating means for actuating the attachment member, fastened to said half-tract at a hinge, being connected to the distal half-tract; and wherein the two half-tracts are fastened one to the other one by means of a pair of hooking plates comprising a through-hole and a fastening pin constitutes an extension of the first half-tract, so that by disassembling the fastening of the pair of plates it is possible re-mounting the second half-tract axially rotated by 180° with respect to the first half-tract, by rotating by 180° even the respective arm-actuating means.
