Elevator renewal method and elevator auxiliary panel

An elevator renewal construction method, in which, when renewing at least one device in an existing elevator,

• process of renewal construction work is divided into a series of divided construction work steps, each being determined as such a unit that the elevator operation becomes normally possible after finishing of each of the divided construction work steps, and the renewal construction works are executed in accordance with the series of divided construction work steps,
• the series of the divided construction work steps including a first divided construction work step, the first divided construction work step comprising the steps of:
• replacing an old control panel of the existing elevator with a new control panel;
• installing an auxiliary panel, which includes a communication converter to be connected to the new control panel, and which is formed separately from the new control panel;
• and
• connecting an old device including at least any one of an old hall device and an old car device, which has been placed in a communicable state with the old control panel of the existing elevator, to the communication converter of the auxiliary panel to bring the old device into a communicable state with the new control panel via the communication converter so as to bring the elevator into a normally operable state after finishing of the first divided construction work step in a renewal construction period,
• wherein the new control panel is configured to be communicable with the old device through an old communication system converted via the communication converter included in the auxiliary panel, the communication converter being configured to mutually convert a communication system between a new communication system and the old communication system, and
• wherein the auxiliary panel is configured to be removable from a present place so as to be reusable for renewal construction work at another place.
