Construction machine with a hydraulic system

A construction machine (100) with a hydraulic system with at least one hydraulic control (1), the construction machine (100) comprising multiple components (9) moveable at least relative to one another, the at least one hydraulic control (1) comprising:

• at least one joystick (15);
• at least one hydraulic pressure source (2);
• two hydraulic drives (3) each connected to the at least one hydraulic pressure source (2) by a hydraulic connection (4);
• at least two main control valves (6) provided in each of the hydraulic connections (4), each of the at least two main control valves (6) controllable by the at least one joystick;
• at least one priority valve (7) being an electrically actuatable proportional valve assigned to one of the two hydraulic drives (3) and provided in the hydraulic connection (4) thereof;
• an electronic control unit (14) electrically connected to the at least one priority valve (7);
• and
• electrical movement sensors (12) provided on the movable components (9) for indirect or direct detection of respective positions thereof, the electrical movement sensors (12) are in each case connected to the movable components (9) in order to transfer detected sensor values to the electronic control unit (14),
• wherein a pressure level of each of the two hydraulic drives (3) depends on a working point of one of the hydraulic drives (3) selected in each case,
• wherein each of the multiple components (9) is operatively connected to one of the hydraulic drives (3) for moving one of the multiple components (9),
• wherein the at least one priority valve (7) is controlled by the electronic control unit (14) to generate additional hydraulic resistance,
• wherein in addition, in the electronic control unit (14), on the one hand, at least one trajectory can be stored, and, on the other hand, a control mode can be activated, in which the at least one priority valve (7) can be controlled using the values actually detected in each case by the electrical movement sensors (12) upon actuation of the at least one joystick (15) by the electronic control unit (14) in such a way that the at least one stored trajectory is run by corresponding control of the hydraulic drives (3).
