Abstract

PURPOSE: To accurately detect the damages of a hung steel rope without stopping an elevator by contact between the cut wires of the hung steel rope and a terminal of a sensor.
CONSTITUTION: This device consists of a sensor 6 mounted at a fixed void distance from a surface of a hung steel rope 4 and a terminal 7 electrically contacting with the hung steel rope 4 connected to said sensor 6 through a power source 8, and detects the damage of the hung steel rope 4 when the cut wires 4aW4i of said hung steel rope 4 electrically contact with the sensor 6. Above-mentioned arrangement can detect damages safely and positively without stopping an elevator
