CR coil is loaded on the Coil Car by overhead crane. The coil car travels on rail lines by AC motor & brings the coil to the uncoiler. The lifting cylinder of the coil car centralizes the coil to the Uncoiler centre. The two opposed bodies of the uncoiler are mover towards each other so that the collapsed drums of both the bodies enter the ID of the coil. After proper positioning, the drums are expanded to hold the coil firmly. The coil car is lowered and taken back.
