Abstract

"IMPROVEMENTS INTRODUCED IN POLLING DRILLING MACHINES", characterized in that double-acting hydraulic cylinders have been provided in the drilling head, whose rods that work by traction, are attached at their ends to some plates-support of the axis of rotation and on which the said shaft exerts the ascending or descending thrust; having been provided in addition in the same head columns-guides integral to the aforementioned plates which slide with the assembly on sliding supports of the crankcase of the head.
