Title:
An inspecting method and an inspection device of the buffer made of resin
Document Type and Number:
Japanese Patent JP6246380
Kind Code:
B2
Abstract:
An inspection method and an inspection apparatus capable of readily determining the necessity of replacement of a resin shock absorber at an elevator inspection location without using a car of a rated weight. First, an indenter is pressed into a resin shock absorber for an elevator. A load of pressing the indenter into the resin shock absorber is released. A physical property value indicative of a repulsive force that causes the indenter to bounce from the resin shock absorber by releasing the load is measured. The necessity of replacement of the resin shock absorber is determined by comparing a result of the physical property value obtained by measuring the repulsive force with a reference value prepared in advance.
