Abstract
A device for moving objects by a driving cable. The device features two cable spools enabled to wind and unwind the cable on both sides. A remote cable pulley is arranged for guiding, at a remote location (X), the cable. The cable spools are arranged to exert, by means of constant torque springs, a cable pretension force in a direction (T) contrary to the unwinding direction (U) of the spools. Electric driving means are provided to be coupled either to the one or to the other cable spool, thus causing the cable to move from the one to the other cable spool or reversely, in order to move said one or more objects connected to the cable, or to be disengaged from both cable spools in order to enable manual operation of said one or more objects connected to the cable.
