PROBLEM TO BE SOLVED: To provide a hydraulic control system and construction machines installed with the hydraulic control system in which input values for sensors used for control, set values used in computation for control and instruction values or the like outputted are outputted to a display unit and displayed to an operator and at the same time the operator updates optionally the set values for control to enable the operator himself or herself practically to get an operational feeling desired by the operator.SOLUTION: This invention provides a hydraulic system comprising hydraulic equipment in which a hydraulic pump and a hydraulic actuator connected through a hydraulic passage and a control valve installed between the hydraulic pump and the hydraulic actuator. There are provided sensors installed at the hydraulic passage or the hydraulic pump and the hydraulic actuator, a solenoid proportional valve installed in the hydraulic passage, a controller device connected to the sensors and the solenoid proportional valve and an input/output device connected to the control device and capable of displaying the measurement results of the sensors and inputting parameters and then the parameters can be updated in response to the measurement results of the sensors. |
