MACHINE FOR ROAD CONSTRUCTION, LEVELLING DEVICE, AS WELL AS CONTROL METHOD OF DEPTH OF MILLING OR INCLINATION OF MILLING OF MACHINE FOR ROAD CONSTRUCTION Russian patent published in 2010 - IPC E01C23/88 

FIELD: construction.

SUBSTANCE: in machine for road construction for processing of road surfaces with milling drum adjustable as to height relative to depth of milling, with levelling device at least with one controller which receives the specified values for milling depth and/or inclination of milling drum, and at least with one replaceable sensor or with several switched sensors for recording of actual values of present time of milling depth and/or inclination of milling drum with relatively reference surface. Controller is provided with possibility of controlling the milling depth and/or controlling the inclination of milling drum provided with pre-determined specified value and measured actual values of present time at least of one sensor by returning the controlled value in order to reach or keep the specified value during milling process; at that, levelling device is provided with indicating and setting device for identifying and setting the parametre of the process at least for one sensor. Indicating and setting devices of levelling device in addition to indicator and setting device provided at least for one sensor used at present time is equipped with additional indicating and setting device for the selected sensor by which the sensor used at present time shall be changed.

EFFECT: improving operating reliability of machine and device.
