The multifunctional work platform is characterized in that the multifunctional work platform is mainly composed of a vehicle frame, a lifting arm, a lifting oil cylinder, a hydraulic oil tank, a hydraulic pump, a gasoline engine, walking wheels, a steering wheel, an operating deck, a collecting box and a hydraulic walking motor. The vehicle frame is integrally in a triangular shape, the two walking wheels and the one steering wheel are located on the three vertexes of the vehicle frame, and the steering wheel is connected with the vehicle frame through a steering wheel support. The lifting oil cylinder, the hydraulic pump, the gasoline engine and a protection cover are arranged in the middle of the vehicle frame, and the lifting arm is hinged to the upper portion of the vehicle frame. When the multifunctional work platform works, an operator stands on the operating platform, operates a walking wheel control rod to enable a machine to move forwards and backwards, and operates a lifting control rod to control the lifting arm to go up and down.
