Japanese Patent JP2004123331
Kind Code:
A
Abstract:
To efficiently examine a wear state of a guide shoe to be slidably engaged with a guide rail at a low cost.
Oil feeders 4 and 8 and guide bodies 5 and 7 are provided on an elevator car 2, and scrapers 20 and 21 abutted on a guide rail 3 to scrape a lubricating oil according to the wear of the guide shoe 14 of the guide bodies 5 and 7 are also provided thereon. Since the scrapers 20 and 21 scrape the lubricating oil deposited on an abutting surface of the guide rail 3 when the guide shoe 14 is worn, the friction coefficient of the abutting surface is increased, and a sliding noise occurs between the guide rail 3 and the guide shoe 14 to notify the wear of the guide shoe 14.
