A life saving equipment for roping down persons along a rope has a rack with an inlet opening and an outlet opening for the rope so that the rope passes the rack when the person is roped down. A rope pulley is rotatably mounted within the rack and has on its circumference a groove for the rope. The rope is guided in the groove for a looping angle of more than 180 DEG . The rope pulley can be braked by at least one brake member, the braking force of which can be adjusted by a setting mechanism influenced by the weight of the person to be roped down. A monitoring means checks the presence of the rope within the rack and has a movable sensor member pressed again the rope, preferably by means of at least one spring. The sensor member acts on a rope clamping device for clamping the rope when a rope shortage occurs.
