[0002] Hot-dip galvanizing involves reacting molten metal with an iron substrate to create an alloy layer, thereby bonding the substrate and the coating. Hot-dip galvanizing involves first pickling the steel to remove iron oxide from the surface. After pickling, the steel is cleaned in an aqueous solution of ammonium chloride, zinc chloride, or a mixture of ammonium chloride and zinc chloride before being placed in a hot-dip galvanizing tank. Hot-dip galvanizing offers advantages such as uniform coating, strong adhesion, and a long service life. A lifting device is used during the hot-dip galvanizing process.

[0003] A hot-dip galvanizing sling with application number 202223535209.7 in the prior art can effectively solve the problem of multiple small-sized zinc materials touching or overlapping, which affects the hot-dip quality of the zinc materials. It includes a mounting column; a first connecting rod is rotatably provided on both sides of the mounting column, a second connecting rod is hinged at one end of the first connecting rod, and a clamp is provided at the lower end of the second connecting rod; a horizontal plate is rotatably connected to the middle position of the second connecting rod, and a rotating shaft is installed on the mounting column, and a screw is connected at one end of the rotating shaft.
