The invention provides a hydraulic fault alarm system of an elevator, and belongs to the technical field of elevators. The problem of how to ensure the monitoring stability and the monitoring precision on the basis of reducing the arrangement difficulty of an alarm system is solved. The hydraulic fault alarm system of the elevator comprises a mounting plate, an oil tank, an alarm, a hydraulic motor, a first oil delivery pump, a first oil delivery pipeline and a hydraulic cylinder are arranged on the mounting plate, and a generator which is connected with the hydraulic motor and supplies power to the alarm is further arranged on the mounting plate. The oil outlet end of the hydraulic motor is connected with an oil inlet of the oil tank, the oil inlet end is connected with the first oil delivery pump through the first oil delivery pipeline, the first oil delivery pump is connected with an oil outlet of the oil tank, a pulley is installed on a pump shaft, a first overflow valve is installed on the first oil delivery pipeline, the hydraulic cylinder is connected with the first overflow valve, and an output shaft abuts against the alarm switch. According to the hydraulic fault alarm system of the elevator, the monitoring stability and the monitoring precision can be ensured on the basis of reducing the arrangement difficulty of the fault alarm system.
