Renewal method of elevator

Abstract

The invention provides a renewal method of an elevator, including a first step in which the operation of a hydraulic elevator is maintained and the renewal product is installed at a position without bringing obstruction to the operation of the hydraulic elevator and replaced; a second step in which the operation of the hydraulic elevator is maintained and arrangement of a tractor to the top in a lifting passage is executed; and a third step in which the operation of the hydraulic elevator driven by a hydraulic jack is stopped and a switch operation to a rope-type elevator is executed. In the second step, one rail installed at a position without bringing obstruction to the operation of the hydraulic jack and a temporarily equipped holder disposed between such rail and an inner wall of the lifting passage are arranged in a pair of guide rails for a balancing weight arranged in a lateral space of the hydraulic jack. The holder supports a tractor base of the tractor and the tractor is disposed on the tractor base.

Description

[0001] This application is based on Japanese Patent Application No. 2010-113108 (filing date: 5 / 17 / 2010), and enjoys the priority of this application. This application refers to this application, and includes the entire content of this application. technical field [0002] Embodiment of this invention relates to the update method of an elevator. Background technique [0003] Conventionally, in low-rise apartment buildings with a relatively small number of floors, hydraulic elevators that do not require a machine room above the elevator passage are used. However, in recent years, due to environmental concerns, the adoption of hydraulic elevators using oil has been drastically reduced, and rope elevators are in the majority. Therefore, almost all of the old hydraulic elevators are replaced with machine-room-less rope elevator systems (for example, JP-A-2003-34474). [0004] In the past, the method of upgrading the hydraulic elevator to the latest rope elevator without a mach...

AI Technical Summary

Problems solved by technology

However, since rails for hydraulic jacks are erected on both sides of the hydraulic jack, rails for counterweights cannot be built until rails for hydraulic jacks are removed.

That is, if the track for the hydraulic jack is removed, the elevator cannot be made to work as a hydraulic elevator

[0008] In addition, the traction machine and / or the traction machine bed on which the traction machine is placed in the updated new elevator are arranged on the upper part of the guide rail for the counterweight, so the guide rail for the counterweight These artifacts cannot be set until the

As a result, as mentioned above, the construction content during the complete stop period increases, and thus the complete stop period also becomes longer.
