Abstract

Drilling unit (1) provided with a top drive (10) which is mobile along a drilling axis (A) in order to move drilling rods, with two telescopic drilling masts (6) which are arranged facing each other, a cable device (30) and a hydraulic device (40) which co-operate with each other to move the top drive (10) along a support guide (5) which is parallel to the axis (A) and is arranged in an intermediate position in relation to the two drilling masts (6) for supporting and sliding the top drive (10) along the axis (A); a hydraulic actuator (41) for each drilling mast (6) being suitable for modifying a longitudinal length of the relative drilling mast (6) itself, and a control station (42) being suitable for controlling the actuation of each hydraulic actuator (41) either in contemporary or independent fashion.
