Abstract (en)
[origin: WO2005008075A1] The invention relates to a control and adjustment system for a lifting mechanism (100) of a loading blade (6) in a mobile machine tool. Said lifting mechanism is made up of at least one first and second blade cylinder (1, 2), at least one first and second lifting cylinder (61, 62) and one first and second hydropump (15, 75) which can be adjusted with regard to the pump volume. The adjusting pistons (3, 5) which can be displaced in the first and second blade cylinders (1, 2), respectively, separate both blade cylinders (1, 2) into two adjusting pressure chambers (7 and 8, 9 and 10). The adjusting pistons (63, 65) which can be displaced in the two lifting cylinders (61, 62) respectively separate the two lifting cylinders (61, 62) into the two adjusting pressure chambers (67 and 68, 69 and 70) in an analgous manner. In a first closed hydraulic circuit, a first and the second connection (14, 17) of the first hydropump (15) is, respectively made to the piston side of the piston pressure chamber (7, 9) of one blade cylinder (1, 2) and to the piston rod side of the adjusting pressure chamber (10, 8) of the other blade cylinder (2, 1). The first and second connection (74, 77) of the second hydropump (75) is respectively made in a second closed hydraulic circuit to a piston side adjusting pressure chamber (70, 67) of a lifting cylinder (62, 61) and to the piston rod side of the adjusting pressure chamber (68, 69) of the other lifting cylinder (61, 62).
