A multi-function machine for drilling, boring, driving and lifting comprising a translation system (2) which supports a turret (3) motorized and provided with driving cab. A lattice tower type arm is hinged to the frame of the turret and movable between substantially raised and inclined positions. In at least a first configuration the arm is used as a lifting arm. The free upper end of the arm has a head (9) having a system of pulleys and/or transmissions for rope (10). The arm (4) can rotate with respect to the turret (3) to acquire a second configuration of mounting/transport wherein its longitudinal axis is substantially horizontally arranged and turned over toward the front. Ropes and rods are provided (14,16) for bringing the arm from the first to the second configuration and vice-versa. The arm (4) can acquire a third operating configuration wherein its longitudinal axis is substantially vertically arranged; in said third configuration the arm (4) is a guide for a digger/drill (27) sliding in a direction substantially parallel to the longitudinal axis of the arm; being also provided an actuator (8) for maneuvering the arm (4) at least in the third configuration.
