Abstract
The handrail is an important part of the escalator, which moves synchronously with the steps to ensure the safety of passengers. It is one of the common failures of escalator equipment that the handrail is out of synchronization with the step operation. If the handrail is not synchronized with the step operation or even stops running, passengers will fall down. In this paper, a failure case of the driving chain of the escalator handrail is analyzed macroscopically and microscopically. The research results show that the serious wear of the pin shaft and sleeve of the escalator handrail drive chain is the main reason for the handrail drive chain.
