Through ingenious fixing methods, a kind of work platform is achieved. When it is raised, the four braces of the chassis are automatically supported on the ground; when the working platform is lowered, the wheels touch the ground, which can be easily pushed and moved by manpower. However, the ground clearance of this platform is generally low, and the passability is poor. The road surface of the ramp is inconvenient to pass. What the aerial work platform of this invention patent moves adopts manpower to move, is not automatic walking. CN103539037A discloses an aerial work platform, which is an aerial work platform with a complex control system and high cost. Its control panel is set on the work platform, and a person standing on the work platform controls the walking and steering of the platform through the control panel. In addition to the remote control system, the realization of the platform steering function also requires the actuator of the mechanical transmission part. The mechanical transmission and control system is complex and expensive.
