The present invention relates to a sea-hook device for moving the hot rolled and cold-rolled coils produced in a steel mill to a required position in the production process. More specifically, the hook portion of the sea-hook device can be briefly moved when the coils are closely stacked. The coil can be moved after it is folded and entered into the inner circumference of the coil, so that the coil can be moved and moved smoothly even if the stacking space of the coils is reduced as compared with the conventional sea hook. It relates to a sea hook device.

In general, steel mills produce slabs that have undergone steelmaking, smelting and reprocessing as strips, which are produced by rolling, into coils. These coils can be divided into hot rolled and cold rolled coils. In order to move the coil using a seed hook, i.e., a C-shaped seed hook which is supported by the inner winding of the coil, the conventional seed hook is shown in FIG.
