The aerial and ground rotation groups are devices that hooks and turns a pinion installed on the placementing support of the painting item.
This system is composed by a structure specifically designed with the kinematics (pinions, joints, chains, pneumatic cylinder) that allows the skid rotation where are placed or hanged the painting item.
This system also permits to control the rotation on the basis of a programmed sequence. The managing values during the rotation are angle, vector and speed.
At the end of painting operation, the rotation group replaces the item at the original position or in a new position.
