In an elevator renewal method, a first segmented construction step among a series of segmented construction steps comprises: a step for installing a communication-type landing device in a landing; a step for installing a communication-type car device in a car; a step for installing a communication relay device and interconnecting the communication relay device and an old control panel; and a step for interconnecting the communication relay device and the communication-type landing device and interconnecting the communication relay device and a communication-type car device. After the first segmented construction step has concluded, the old control panel will be able to communicate with each of the communication-type landing device and the communication-type car device via the communication relay device.
Description
technical field [0001] The invention relates to a refurbishment method for elevators. Background technique [0002] Existing elevators are refurbished in order to cope with the aging of equipment or to improve performance such as energy saving. In this case, it is necessary to continuously suspend the operation of the elevator for a long period of time during an elevator renovation project in which at least a part of the equipment of the existing elevator is renovated. Therefore, the long-term suspension of the elevator becomes a major obstacle to renovation. [0003] Therefore, there has been proposed an elevator refurbishment method that shortens an elevator continuous stop period during an elevator refurbishment work period (for example, refer to Patent Document 1). [0004] prior art literature [0005] patent documents [0006] Patent Document 1: International Publication No. 2018 / 109946 Contents of the invention [0007] The problem to be solved by the invention...
