Abstract: With the development of intelligent insulating aerial device, the operation of insulating aerial device is becoming increasingly difficult for operators to quickly grasp, and even in the event of emergencies, there may be situations of panic. Develop an insulating aerial device with an operation indicator device. The operating system of the insulating aerial device adds an operation indicator light on each operation button, and the operator can judge the feasibility of the action by the color of the indicator light. At the same time, there will be an alarm sound to remind when the action cannot be continued. The result proves that the insulating aerial device using this device is easier for operators to control.
