DOUBLE DECK ELEVATOR

摘要

A double deck elevator comprises a winding machine (13) which lifts up/down a cage frame (1) loaded with two cages (2, 4) in a vertical direction, a cage driving unit (10) which changes a relative distance between upper and lower cages, and a cage position controller (16) which starts an inter-cage distance adjustment operation of the cage driving unit almost at the same time when the winding machine is shifted from an acceleration operation to a constant velocity operation, and changes an operating velocity of the inter-cage distance adjustment operation corresponding to a destination floor almost at the same time when the winding machine changes from the constant velocity operation to a deceleration operation after the destination floor is determined, whereby completing the inter-cage distance adjustment operation almost at the same time when the winding machine stops.
