PROBLEM TO BE SOLVED: To provide a construction machine capable of improving the operability of inching operation even when a load pressure is a predetermined pressure or higher.SOLUTION: The construction machine includes a pump, an actuator connected to the pump via a selector valve and adapted to be driven by oil discharged by the pump, a first pressure sensor for detecting the pressure of the oil discharged by the pump, a second pressure sensor for detecting oil pressure between the selector valve and the actuator, a negative control pressure sensor provided between the selector valve and a tank, and a controller. The controller corrects a control target value for the pump determined depending on oil pressure detected by the negative control pressure sensor, depending on a differential pressure between the oil pressure detected by the first pressure sensor and the oil pressure detected by the second pressure sensor. |
