Drive comprising a set of safeties that can be bidirectional or unidirectional. In the case of the bidirectional system, it is formed by two wedge rollers (1) and (2) that run through oblong grooves (11) and (12) respectively provided in a protective plate (16). The wedge rollers (1) and (2) are assembled onto floating anchors (14) and (15) respectively, which anchors are linked together by means of a spring (5) ; on the other hand it comprises a drive assembly comprising a coil (3) where the transmission between the drive and the wedge assembly is carried out by means of a flexible transmission comprising two cables (7) and (8) joined at one of their ends to the drive assembly and at the other end to the floating anchors (14) and (15) on which the wedge rollers (1) and (2) are mounted. In addition, the bolts of the rollers (1) and (2) run through the oblong holes of a discriminating plate (6) which is responsible for separating the non-wedged roller from the guide. This system allows separate mounting of the wedge assembly with respect to the drive assembly.
