1. An electromechanical drive by flexible transmission for the activation of lift safeties comprising a bidirectional wedge assembly comprising:
a first wedge roller and a second wedge roller that run through a first oblong groove and a second oblong groove, respectively, on a protection plate, said first and second wedge rollers are mounted on a first floating anchor and a second floating anchor, respectively, and the first and second floating anchor joined together by means of a spring;
a drive assembly comprising a coil characterized in that a transmission between the drive assembly and the wedge assembly is carried out by means of a flexible transmission comprising a first cable and a second cable joined at one end to the drive assembly and at the other end to the first and second floating anchors on which the first and second wedge rollers are mounted, respectively;
wherein the first and second floating anchors are mounted on a discriminating plate.
