A swing state detection device for a swing machine, characterized in that the swing machine includes the following configuration. () At the position opposite to the teeth of the ring gear above,
Two proximity sensors for detecting the number of passing teeth of the ring gear when the upper revolving body rotates are provided with a phase difference in their outputs. () It must have a controller to which detection signals from both proximity sensors are input. () This controller includes a turning direction determination section that determines the turning direction of the upper rotating structure based on output signals with a phase difference from both proximity sensors, and a turning direction determining section that determines the turning direction of the upper rotating structure based on the sensor output signal. and a turning angle calculation unit that calculates the turning angle.
