Peter Lunati, a technician looking for a better way to repair a car, was inspired by the sight of a barber chair rising in the air. If you can lift a chair, why not an automobile? Not even a year later, in 1925, Lunati built the world's first automotive hydraulic lift. And Rotary Lift, the Company, was born.More than 80 years later, Rotary has grown to become the world leader in lift productivity. Global operations extend from our headquarters in Madison, Indiana, throughout North and South America, Europe and Asia.
