[0002] Cold-rolled coil is made of hot-rolled coil as raw material and is rolled below the recrystallization temperature. It includes plates and coils. The ones delivered in sheets are called steel plates, also called box plates or flat plates; the ones delivered in long lengths in coils are called steel strips, also called coils.

[0003] Due to the heavy weight of cold-rolled coils, it is difficult to carry the cold-rolled coils onto the vehicle by manpower when loading them onto the vehicle. A hoist is required to lift the cold-rolled coils onto the vehicle. Most of the existing cold-rolled coil hoists require additional lifting accessories to be installed outside the cold-rolled coils to hang the cold-rolled coils on the hooks of the hoists, which undoubtedly increases the loading time and reduces the loading efficiency of the cold-rolled coils. Therefore, a hoist for cold-rolled coils is proposed to solve the above problems. Utility Model Content

[0018] Through the above arrangement, the lifting ring 1 is hung on the lifting tool, the cylinder 3 is started, the cylinder push rod 4 is pushed out, and the first fixed seat 5 moves downward accordingly, thereby driving the three first articulated seats 6 and the three sliding bars 11 to move downward together, and the three sliding bars 11 will slide downward along the inner sides of the three sliding holes 10, thereby the three clamping claws 9 will shrink inwardly. At this time, the entire device can be extended into the cold-rolled coil, and then the cylinder push rod 4 is controlled to retract, and the first fixed seat 5 moves upward accordingly, thereby driving the three first articulated seats 6 and the three sliding bars 11 to move upward together, and the three sliding bars 11 will slide upward along the inner sides of the three sliding holes 10, thereby the three clamping claws 9 will expand outwardly, and the three fixing components 12 will contact the inner side of the cold-rolled coil, and the fixation with the cold-rolled coil is completed by friction. When the lifting tool lifts the lifting ring 1 upward, the cold-rolled coil can be lifted onto the transport vehicle.
