Abstract:
1. An elevator modification work apparatus applied to an end surface of a rotatable motor shaft of a motor having the motor shaft and a motor frame provided around the motor shaft, the elevator modification work apparatus comprising: a positioning member having a plate shape with opposed surfaces; a recess in one of the opposed surfaces of the positioning member, the recess having a depth that is less than a thickness of the positioning member between the opposed surfaces such that the recess does not extend entirely through the positioning member in the thickness direction, whereby the recess has a bottom surface, wherein the recess has a shape and size permitting the end of the motor shaft to be inserted therein, and permitting the positioning member to rotate in a direction of rotation of the motor shaft while prohibiting movement of the positioning member relative to the motor shaft in any direction perpendicular to the direction of rotation of the motor shaft when the end of the motor shaft is inserted into the recess and the elevator modification work apparatus is applied to the end surface of the motor shaft; and at least one motor shaft positioning aperture that passes through the positioning member from the other of the opposed surfaces in a direction that intersects the bottom surface of the recess.
