Abstract
First to third inertial sensors () are respectively mounted on a boom (A), an arm (B) and a bucket (C) to rotate in coordinate axes different from each other at the time of operating the boom (A). In a case where the boom (A) is operated in a state where a traveling operation pressure Pa and a revolving operation pressure Pb are equal to or less than respective preset operation pressure threshold values, a controller () makes a determination on which movable part of the boom (A), the arm (B) and the bucket (C) each of the inertial sensors () is mounted, based upon sensor outputs outputted from the inertial sensors (). The controller () sets a corresponding relation between each of the boom (A), the arm (B) and the bucket (C) and each of the inertial sensors () based upon the determination result.
