Aerial work platform

The invention relates to an aerial work platform. The aerial work platform comprises a platform chassis, a walking device, a lifting device, a work platform and a control unit. The work platform comprises a fixed platform and a movable platform, the movable platform can horizontally move in a telescopic mode towards at least one direction on the fixed platform, and the fixed platform is connected to the top of the lifting device. The aerial work platform is characterized in that the platform chassis is connected with at least one telescopic ground supporting foot supported on the ground, and the telescopic direction of the ground supporting foot is the same as that of the movable platform. The aerial work platform is simple in structure, has the functions of planar moving, longitudinal lifting and transverse telescoping, enables a scissor-type lifting platform to move flexibly, and facilitates timely work. Through change of the position of the supporting foot, the safety work area of the work platform is obviously increased, and the accidents of side turning and the like due to the fact that the side surface bears much are effectively prevented.
