FIELD: construction.
SUBSTANCE: device for synchronous actuation and locking of lift doors, such as a cabin door and a floor door, which are arranged mainly one behind another in a movement direction, includes drive rollers (9, 10) attached to the first door with variable distance between them; with that, movement of drive rollers (9, 10) is set by means of elongated holes (16, 17), in which pins (18) move and retain drive rollers; as a result of which, at movement of elongated holes along the pins at least in some areas the distance between the drive rollers changes. A lift system includes the above described device.
EFFECT: group of inventions ensures simplification of the structure.
