Abstract

The steel wire ropes that hoist elevators will eventually become rusted and then cracked as they always expose to air that contains high salinity content. A number of rope broken accidents occurred because of inappropriate maintenance that causes the ignorance of broken wires in a steel rope. Elevator ropes have very complicated structure as they are formed by twisted many small wires together to form a bigger rope. Such complicated structure creates difficulty to currently available non-destructive evaluation methods. To avoid the accidents, proper maintenance equipped with effective non-destructive testing method that must be presented. However, as of today, most of the elevator rope inspections are depends on human visual inspection. Such inspection fails to detect faults occurred in internal wires and even external wires due to the covering of grease on the ropes. The aim of this study is to introduce a new and effective technique based on ultrasonic guided waves for inspecting the faults occurred in internal and external wires. The experimental results demonstrate that the ultrasonic guided wave can detect the locations of broken wires and then determine the number of broken wires effectively. The experimental results also show that the PZT sensor is more suitable for working as a transmitter/emitter and the MsS is better working as a receiver. For grease covered ropes, the results show that the range of inspection distance will be decreased due to the attenuation of the reflected signal energy. Nonetheless, the reflected signal caused by the defects can still be clearly observed even the rope was covered by grease. Although the current results are promising, more sophisticated method must be developed so that the proposed technique can be applied to on-site ropes tests. The future research may include the development of optimizing the operation parameters of guided wave and the design of practical sensor for operating ropes.
