[0013] According to the above technical solution, the present utility model provides a galvanized coil lifting device, which includes a central cross beam. Right-angle beams that are slidably sleeved at the ends of the central cross beam are provided at both ends of the central cross beam. A hook is connected to the outer end of the right-angle beam. An insertion hole that inserts into the central cross beam is provided at the inner end of the right-angle beam. T-shaped grooves that penetrate in the width direction are provided on the top sides of both ends of the central cross beam. A strip-shaped middle hole that extends along the length direction parallel to the central cross beam is provided on the top side of the insertion hole.

Adjacent two of the screws are arranged in a staggered manner. A suspension ring is provided in the middle of the central cross beam.

[0014] The usage method and beneficial effects of the galvanized coil lifting device are as follows: First, by sliding the right-angle beams at both ends, the hooks at both ends are adjusted to a suitable position for lifting the galvanized coil. At the same time, it is ensured that the right-angle beams at both ends are adjusted synchronously, so that the right-angle beams at both ends are always symmetric with respect to the central plane of the central cross beam to ensure balance at both ends. Then, the hook of the crane is hung on the suspension ring, and the hooks at both ends are hooked on both ends of the galvanized coil, thereby realizing the lifting of the galvanized coil. Since the right-angle beams at both ends can be slid to adjust the position, the galvanized coil lifting device can adjust the distance between the hooks at both ends according to the length of the galvanized coil to be lifted, and has high versatility. In addition, since adjacent two of the screws are arranged in a staggered manner and are respectively limited in the corresponding side holes, it is difficult to pull out the right-angle beams at both ends after the nuts are locked, strengthening the installation stability of the right-angle beams.
