FIELD: transport.
SUBSTANCE: invention relates to elevators and is intended for controlling movement of lift cabin group in single well. Control device contains the first and the second relay switches (52, 56), door monitoring unit (46). In the process of controlling movement of lift cabin (22, 24) group, door monitoring unit (46) determines position of each cabin (22, 24), condition of each door of well (30, 32, 34), well (30, 32, 34) door opening. Door monitoring unit (46) opens contacts of relay switches (52, 56) when lift cabin (22, 24) stops at lift landing. Door monitoring unit (46) opens contacts of relay switches (52, 56) when none of cabins (22, 24) is stopped at landing corresponding to at least one open door (30, 32, 34).
EFFECT: higher safety.
