Then the staff holds the handrail 7 and moves the cross arm lifting tool 11 above the side of the foil roll. Then the staff flips the cross arm lifting tool 11 through the handrail 7 to hook the core shaft 14 with the hook 4. After hooking, start the speed reducer inside the electric hoist 9, and then the reel foil 10 can be lifted.
[0032] During the process of the hook 4 hooking the core shaft 14, the distance can be adjusted according to the length of the workpiece. When the distance needs to be adjusted, first remove the indexing draw pin 3, and pulling out the indexing draw pin 3 can slide the hook 4 to adjust the lifting position.
[0033] The utility model completes the handling of heavy objects of the reel type through the design of the cross arm hook structure of the shoulder pole type.
[0034] It should be noted that the bottom of the reel foil hanging box 12 is on the ground. Before hoisting, the core shaft 14 is placed at the semi-circular through hole 13. During the hoisting process, the combination of the reel foil 10 and the core shaft 14 will be hoisted.
