Turnstiles

A Turnstile is a component used on the entry and/or exit end of coil processing line for coil storage. A turnstile has one arm, two arms, three arms, or four arms with a c-hook slot to place and remove material with a crane. Turnstiles for heavier coils are turned with a hydraulic motor. Sometimes an exit turnstile for a slitting line will have a hydraulic pusher to push slit coils onto a downlayer for further packaging on a coil banding line. You will usually see a turnstile on a slitting line and cut to length line, and sometimes on a pickling line, galvanizing line, tube and pipe mill, rollforming line, or spiral pipe mill.
