Automatic propulsive construction machinery

The utility model relates to an automatic propulsive construction machinery and the method that is used for controlling automatic propulsive construction machinery. When construction machinery marchd, extended or the withdrawal operating system (6) of anterior running gear (4), makes on machinery frame (2) keeps being in predetermined orientation for ground B's surface in vertical direction. , construction machinery can detect ground irregularity degree on the surface when marcing, because the position of a plurality of anterior operating system (6) can be predetermined, right by control or regulating unit (14) monitor the position so that mechanical frame (2) are surperficial for ground in predetermined orientation. When construction machinery marchd, rear portion operating system's control was controlled according to anterior operating system and is gone on with the delay mode. Consequently, construction machinery's work systems can be adjusted the exact height for the ground surface to make work systems can not duplicate the route on ground.
