摘要
A powered drive (10) for moving gates and barriers comprises a mechanical motion transmission (12) along which are a drive shaft (18) and a corresponding driven shaft (19). Between the driven and drive shafts is a mechanism (20) which by operating setting means (25) allows immediate conversion of the coupling between the drive and driven shafts into a coupling with reversible or irreversible motion transmission depending on need.
