[0002] A packaging coil is a cylindrical container used to hold, store and transport rolled packaging materials. This tube is usually made of paper tube, plastic tube or metal tube. Its diameter, length and thickness will vary depending on the characteristics and size of the required packaging material. The packaging coil provides structural support when the rolled packaging material is wound and stored, maintaining its shape and stability, and helps to prevent the coil from collapsing or deforming. Lifting equipment is required to assist in the handling of the packaging coil.

[0003] However, when lifting the packaging coil lifting equipment in the prior art, two sets of support rods are first used, and the support rods are inserted from both sides of the coil drum, and then the lifting equipment is used to connect and fix the support rods for lifting.
