Zusammenfassung:	A mechanical door lock with a control device for an industrial elevator is provided to prevent a safety door from being opened forcedly by installing a hook and a latch between the safety door and a door of a carrier. A mechanical door lock with a control device for an industrial elevator comprises a push rod and a locking structure(40) having a hook(42) and a latch(44). The push rod is installed at a door of a carrier. The hook is installed to a door frame of a safety door(30). The latch, which is installed to the safety door by a hinge(41), operates like a seesaw. The latch is unlocked by the push rod moving when the door of the carrier is opened, and then opens the safety door. The carrier is interlocked with the door which is opened by an arrival signal. When the safety door is unlocked, the elevator is opened automatically.
