Abstract

The apparatus (1) has a preset piano wire (11) and a specific piano wire (12) which are installed in the both sides of the hall door opening portion of the hoist way of the lift in parallel along a perpendicular direction. A preset clamp (41) holds a pair of guide rail for buckets which guides a cage. A specific clamp (42) holds a pair of guide rail for weights which guides a counterweight. A rail holding jig (20) is positioned by using gauge portion (30) that combines a relative position with respect to the three places of preset piano wire and specific piano wire.

Description

[0001] This application is based on and claims priority from Japanese Patent Application No. 2011-187964 filed on August 30, 2011, the entire contents of which are incorporated herein by reference. technical field [0002] One embodiment of the present invention relates to a centering device and an alignment method (alignment) of a guide rail arranged on an elevator shaft.
