The Crater Tire CT 4.0 Double is equipped with a skiving robot to process defects on previously buffed casings. The robot, equipped with a gripper, loads the tyres fully automatically from the monorail, which independently sets up the hooks for gripping. The robot loads the tyre one at a time and inserts it first on the first tripod, the system starts to scan it by means of a sensor that identifies the defects on the crown. Once this has been done, the first internal robot will start processing it using abrasive tools, while the loading robot will take the second tyre previously positioned by the monorail and load it into the second tripod where the second robot, after performing a new scan, will process the defects.
