Description

Technical Field

[0001] This utility model relates to the field of maintenance tool technology, and in particular to a tool for replacing the hydraulic rod of the escape window of a CRH5A high-speed train. Background Technology

[0002] The hydraulic actuators of the escape windows in the driver's cab of the CRH5 high-speed train are damaged and malfunction due to frequent opening and closing during driver observation and maintenance operations. This results in the escape windows becoming unusable or even failing to function properly. This issue occurs more than a dozen times a year, and the hydraulic actuators must be replaced to resolve the problem.
