Abstract
A swiveling work machine includes: a swivel base rotatable about a swivel axis extending in an up-down direction; a working device provided on the swivel base; a position detector provided on the swivel base to detect a position; and a calculator to calculate an orientation of the swivel base based on a detected position which is the position detected by the position detector, in which the calculator is configured or programmed to calculate an axis position which is a position of the swivel axis based on a plurality of the detected positions obtained during rotation of the swivel base about the swivel axis, and calculate the orientation of the swivel base, based on the axis position and the detected position.

A swiveling work machine comprising:
- a swivel base rotatable about a swivel axis extending in an up-down direction;
- a working device provided on the swivel base;
- a position detector provided on the swivel base to detect a position;
- and
- a calculator to calculate an orientation of the swivel base based on a detected position which is the position detected by the position detector, wherein
- the calculator is configured or programmed to
- calculate an axis position which is a position of the swivel axis based on a plurality of the detected positions obtained during rotation of the swivel base about the swivel axis, and
- calculate the orientation of the swivel base based on the axis position and the detected position.
A method of detecting an orientation of a swiveling work machine, comprising:
- a first step including causing a swivel base provided with a working device to rotate about a swivel axis extending in an up-down direction and causing a position detector provided on the swivel base to detect a plurality of detected positions;
- a second step including calculating an axis position which is a position of the swivel axis based on the plurality of detected positions detected by the position detector;
- and
- a third step including calculating an orientation of the swivel base based on the axis position calculated in the second step and a current detected position.
