Abstract (en)

[origin: EP1357073A1] In an elevator main rope elongation detector apparatus, electrical resistance of an electrically-conductive filament integrated into a main rope is measured by an electrical resistance measuring apparatus. A determining means determines whether a measured value from the electrical resistance measuring apparatus is within a preset normal range. When the measured value is determined by the determining means to be outside the preset normal range, a warning is issued by a warning means. <IMAGE>
