FIELD: transport.SUBSTANCE: proposed machine comprises chassis 10, two front and two rear supports 20, 22. Said supports may turn from transport position to bearing position with changed datum angle (?) between support and chassis and/or they may be drawn apart to vary their length between mount end and free end. For automatic determination of bearing leg position (X/Y) relative to chassis 10 three transceiving units (S/E, S/E, S/E) related to every support for transmission and reception of signals of travel time or distance signals. Besides, there is microprocessor-controlled processing unit responding to signals of said units and incorporating program defining support leg position in fixed coordinate system.EFFECT: higher operating performances.8 cl, 4 dwg |
