The invention relates to a telescopic handler side flat action protection system. The risk caused due to the fact that a side flat button is operated by mistake when a telescopic boom is in a hoisting and loading state is avoided. The system is simple in structure, safe and reliable. According to the technical scheme, the system comprises the telescopic boom, a frame and a front and rear axle, a frame side flat mechanism is arranged between the frame and the front and rear axle, and provided with a proportional electromagnetic valve Y1, a proportional electromagnetic valve Y2, a telescopic boom lifting state detecting switch S1, a side flat function allowing switch S2, a proportional valve controller E01, a side flat action switch S3 and a micro sensor E02, the proportional electromagnetic valve Y1 and the proportional electromagnetic valve Y2 are used for controlling the frame to swing left and right, and the telescopic boom lifting state detecting switch S1 and the side flat function allowing switch S2 are electrically connected with the proportional valve controller E01, and control the proportional valve controller E01 to be powered on and off together. The proportional valve controller E01 is electrically connected with the side flat action switch S3, and the side flat action switch S3 is controlled to be powered on and off. The side flat action switch S3 is electrically connected with the proportional valve controller E01 through the micro sensor E02.
