Claims

[Claims for Utility Model Registration] 1. A swivel base rotatably mounted on a base; a swivel drive means with adjustable drive speed for driving the swivel base; a storage and holding means disposed on the base for storing and holding the working device; and whether the swivel base is located in a storage position where the working device is stored and held by the storage and holding means. storage position detection means for detecting whether or not the working device is stored; an automatic storage switch that is activated when the working device is stored; and rotate the swivel base toward the storage position at low speed, and when the storage position detection means detects that the swivel base is located at the storage position,
An automatic retraction control device for a swing work device, characterized in that it is comprised of an automatic storage swing control means for stopping the drive of the swing drive means. 2. A swivel base rotatably mounted on a base; a swivel drive means capable of adjusting the drive speed for driving the swivel base; a working device disposed on the swivel base; and the working device. storage and holding means disposed on the base for storing and holding the work device; and storage position detection for detecting whether the swivel base is located at a storage position where the working device is stored and held by the storage and holding means. means; deceleration area detection means for detecting whether the swivel base is located in a deceleration area set in a predetermined rotation angle range centered on the retracted position; and activated when the working device is retracted. an automatic retraction switch; when the automatic retraction switch is actuated and the deceleration area detecting means detects that the swivel base is outside the deceleration area, the swivel base moves to the normal speed; When it is detected that the swivel is in the retracted position, the swivel drive means is decelerated and the swivel is swung toward the retracted position, and the swivel is positioned at the retracted position by the retracted position detection means. 1. An automatic retraction control device for a swing work device, comprising: an automatic storage swing control device that stops driving the swing drive device when the rotation drive device is detected.
