摘要

Problem to be solved: to provide a construction machine capable of determining which of the plurality of hydraulic actuators is abnormal in a simple configuration.Construction machinery according to the present inventionA first flow rate detector (17V) for detecting the flow rate of drain operating oil discharged from a first hydraulic actuatorA second flow rate detector (18V) for detecting the flow rate of drain operating oil discharged from a second hydraulic actuatorAbnormality of the first hydraulic actuator is determined based on the detection signal from the first flow rate detector.An abnormality determination part (31) for judging the abnormality of the second hydraulic actuator based on the detection signal from the second flow rate detector andEquipped withA first flow rate detector and a second flow rate detectorRespectivelyDrain hydraulic fluid passageA moving body (62) disposed within L3 and is urged in a direction to prevent the flow of drain operating oil andAn output part (65) which outputs a detection signal corresponding to the amount of movement of the moving object and.
