Abstract

The present invention relates to a slewing drive for a loading and / or unloading device, a loading and / or unloading device equipped with a slewing drive, a tire heating press, and a method for operating a tire. According to the present invention, linear driving motion is converted into rotational motion, enabling precise and smooth slewing motion. The linear motion axis of the linear drive is parallel to or identical to the rotation axis of the slewing drive.
