Abstract: A drilling machine includes a main body, a mast to mount a drilling tool, a kinematic mechanism movably constraining the mast to the main body while allowing mutual rotation. The kinematic mechanism includes an elongated component hinged at two ends. When the drilling machine is in a drilling configuration, the elongated component performs a structural function to constrain the mast to the main body. An assembling and moving equipment includes a moving element movably mounted to the drilling machine and supporting the elongated component. A moving actuator controls the relative position between the moving element and a mounting portion of the drilling machine. When the drilling machine is in an assembling configuration, one end of the elongated component is released and the moving element acts upon the elongated component. Moving the moving element relative to the mounting portion of the drilling machine causes rotation of the elongated component.
