台平衡保持装置。In an aerial work vehicle equipped with a hydraulic cylinder mechanism to maintain the workbench attached to the tip of the boom in equilibrium with the ground, a viscous electrolyte is sealed in a glass tube container and multiple electrode plates are installed. A slope control device including a slope sensor provided and a bridge circuit connected to the slope sensor is fixed to the workbench, and a slope control signal detected by the slope control device is transmitted to a point near the workbench. Transmission is transmitted to the solenoid valve of the hydraulic unit attached to the boom, and by switching the pressurized oil flow path by energizing or demagnetizing the solenoid valve, the balanced hydraulic cylinder that connects the boom and the work platform is expanded and contracted to maintain the work platform horizontally. A work platform balance maintaining device for an aerial work vehicle, characterized by:
