ABSTRACT:
In a positioner according to the present invention, the rotating table and a hollow shaft is rotated by a motor via a speed reduction gear. In such a configuration, an air tube and a cable which supplies the air or electric power used to operate a jib on the rotating table are provided via the rotary joint arranged at one end of the shaft. A communication device may be provided on the rotating table by detaching the rotary joint and arranging a composite curl cord. The communication device may be provided by the rotary joint and a wireless communication device without using the composite curl cord.
