[0002] Column-type aluminum coils refer to continuously rolled, hollow aluminum materials. During the production process, aluminum coils often need to be transported to designated locations. To protect and improve the handling efficiency of aluminum coils, they are sometimes first carried on pallets and then transported by lifting equipment. Currently, most of the limiting structures of lifting equipment are designed for pallets, and the limiting measures for coils are too simple. When the lifting equipment is transported at high speed, the coil may tip over and fall, causing structural damage to the coil and safety accidents. It also cannot meet the limiting requirements of various types of coils. Summary of the Invention

[0032] The adjustable spreader described in this embodiment has a drive assembly that adjusts the clamping range of the spreader by driving the two clamps to move closer or further apart, meeting the handling needs of various roll materials. After the two clamps grip the roll material, two limiting members clamp the roll material from both sides, achieving the limitation of the roll material and effectively reducing the phenomenon of roll material tipping over during high-speed handling. The drive assembly adjusts the distance between the two limiting members by driving them to move closer or further apart, enabling the two limiting members to clamp different types of roll materials, thus improving the compatibility of the spreader.

The first and second connecting rods use the clearance space to avoid workpieces 9 of different diameters, so that the third connecting rod can support the pallet 8 from the middle. The upper ends of the first and second connecting rods are slidably connected to the slide rail 12.

[0047] The working principle of the adjustable lifting device described in this utility model is as follows:
[0048] The workpiece 9 is placed on the pallet 8. The crane moves the two clamps to both sides of the workpiece 9. The crane hoisting mechanism lowers the height of the lifting device until the third link of the two clamps is lower than the pallet 8. Then, the drive assembly drives the two clamps to move closer to each other until both third links are at the bottom of the pallet 8. Next, the drive assembly drives the two limiting parts to move closer to each other until they clamp the sides of the workpiece 9. Then, the crane raises the lifting device so that the two third links lift the pallet 8. Finally, the crane moves the lifting device to transport the workpiece 9 to the designated position.
[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.

However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
