Pandjiris® Turning Rolls

Constant Centerline

Pandjiris® manufactures a complete line of constant centerline turning rolls.

The constant centerline models include:

Pandjiris® The Piper Series

THE PIPER SERIES with a capacity range of 1,500 lbs. to 10,000 lbs: Mini Pipers, Piper 3, and Super Piper. Designed for the smaller capacity applications, these turning rolls are no light weights when it comes to providing the same reliability and endurance of the larger models.

Pandjiris® The Tanker Series

THE TANKER SERIES with a capacity range of 8,000 to 15,000 lbs.: Tanker 80/40 and Tanker 150/75. Pandjiris® designed these Turning Rolls to meet the needs of the weld shop that handles a wide range of diameter sizes. Since there are no wheel adjustments for different diameters, they maintain a constant centerline, providing a quick change over from one size workpiece to another.

The Missouri Mule Series

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.
