CaterpillarTwo new double-drum asphalt compactors, the CB-534D and CB-534D XW, have drum widths of 67 and 79 inches, respectively. The machines feature automatic speed control with an impact-spacing indicator, new operator's station with an electronically controlled propel lever, five amplitude settings (standard) and a vertical-yoke frame that allows drum-width changes and better visibility.
