PURPOSE:To perform rapid and correct work by connecting a parallel lifting device for supplying additional oil to the hydraulic jack of each outrigger, then receiving the signals of a vehicle width inclinometer, a vehicle length inclinometer and diagonal inclinometers, and lifting a body as it is in the inclined state to make these inclinometers horizontal by the command of an arithmetic and control unit. CONSTITUTION:A body 10 is provided with an arithmetic and control unit 10 receiving the respective signals of a first diagonal inclinometer 42 for detecting the inclination in the first diagonal direction of connecting the hydraulic jacks 18, 18 of outriggers 13L, 14R, a second diagonal inclinometer 43 for detecting the inclination in the second diagonal direction of connecting the hydraulic jacks 18, 18 of outriggers 13R, 14L, a vehicle width inclinometer 40, and a vehicle length inclinometer 41. The same quantity of pressure oil is additionally supplied into the extended side oil chambers of all hydraulic jacks 18, and then the parked body is lifted as it is in the inclined state. Each oil quantity to be additionally supplied is further computed to send a command to a parallel lifting device 30, and the specified oil quantity is additionally supplied to the extended side oil chamber of each hydraulic jack 18 by a make-up circuit 35 to make the body horizontal. |
