Self-walking building machinery

The utility model relates to self-walking building machinery which comprises a machine frame and a bottom disc. The bottom disc is provided with walking mechanisms supported on the ground. According to the self-walking building machinery, the supporting force exerted on the walking mechanisms by the building machinery is measured in the operation mode for adjusting the working depth of a working device, wherein the fact that the building machinery is lowered in a controlled or non-controlled mode is deduced according to the supporting force. The building machinery further comprises a measuring device which is provided with a part used for measuring the supporting force exerted on at least one of the walking mechanisms by the building machinery. The building machinery further comprises an assessing unit, if the supporting force exceeds a preset critical value, the assessing unit generates electronic control signals according to the measured supporting force, the control signals represent that the building mach
