Abstract

The present invention relates to a rotating head of a drilling column with clutch coupling. It comprises at least a motor assembly (2, 3) including in cascade a first hydraulic motor (7), a reduction set (8) with hydraulically commanded clutch coupling (15), a pinion (9) engaged with a crown gear (6) of a structure (1) supporting the rotating head. Even a single motor group (2) further bears, joined coaxially to the side opposite to the first hydraulic motor (7), a second hydraulic motor (10) and a reduction gear (11) connected to the pinion (9) to the side opposite the reduction set (8).
