Traveling control method of telescopic arm crawler crane

The invention relates to a crane technology, and discloses a traveling control method of a telescopic arm crawler crane. The traveling control method of the telescopic arm crawler crane comprises the following steps that a high-speed traveling switching control step is carried out, specifically, a high-speed traveling mode change-over switch is selected; the extension length of a telescopic oil cylinder and the angle of a boom are detected, and whether there is no load or not is judged; the extension length of the telescopic oil cylinder is compared with an extension length threshold value, and the boom angle is compared with an angle threshold value; and when the extension length of the telescopic oil cylinder is not larger than the extension length threshold value, the angle of the boom is smaller than the angle threshold value and the boom is in the no-load state, the switching function between the low-speed running mode and the high-speed running mode is started. According to the traveling control method
