A good entry coil storage system can improve efficiency by reducing line downtime and by allowing efficient use of overhead cranes. The ability to stage multiple coils is crucial as it allows the crane operator to retrieve and load coils whenever it is convenient. Common coil storage devices are turnstiles, saddles, and turntables.
Turnstiles with four arms are suitable for many slitting line applications as they rotate. It allows the line operator to select any coil in any order. Storage saddles support coils from the outside diameter. This design eliminates ID damage on heavy coils and allows easy loading from an overhead crane. Saddles are usually placed in a straight line, which requires the operator to select the coils in a consecutive order.
