Abstract
The electrical wiring harness system of aerial work machinery is affected by mechanical vibration, repeated bending,
and harsh operating conditions, making it prone to various faults that are often difficult to detect. Based on this, this paper takes
the electrical wiring harness of aerial work machinery as the research object, introduces its structure and functions, and
summarizes several common fault types and their causes. Traditional methods such as visual inspection and instrument-based
measurement are briefly introduced. Other nondestructive testing methods, including infrared thermography, ultrasonic testing,
X-ray testing, and time-domain reflectometry, are also analyzed and compared. Finally, the development of intelligent
diagnostic technology is briefly discussed, and comprehensive prevention and detection measures are proposed from four
aspects: design improvement, production process enhancement, inspection and maintenance during operation, and the
establishment of a sound online monitoring system.
Key words： aerial work machinery; electrical wiring harness; fault analysis; nondestructive testing; intelligent diagnosis
