THE MISSOURI MULE (MM) SERIES with a capacity range of 30,000 lbs to 180,000 lbs. or more. These turning rolls are the true work horses of the industry. Designed for heavy-duty use and quick change-over from one size workpiece to another, these turning rolls provide high quality, reliability, and economy by minimizing down time. Since they maintain a constant centerline, they are an excellent choice to use in combination with a manipulator for applications that require both circumferential and longitudinal automated welding.
