Description

Technical Field

[0002] Electrophoresis processing is a surface treatment technology, which is mainly used to apply a uniform, corrosion-resistant coating on the surface of metal or other materials. Electrophoresis technology is widely used in the fields of automobiles, homes, aviation, electrical and electronic appliances, etc. to achieve functions such as waterproofing, corrosion resistance, insulation, and anti-oxidation. Among them, the coating of automobile bodies usually adopts electrophoresis coating technology to achieve good anti-corrosion effect and aesthetics. However, the automobile body is large in size and heavy in weight, which makes its lifting a problem. Existing hoists often use hooks to lift the car, or hang the car by hooks after winding the chain. On the one hand, the existence of these hoists or chains will bring certain scratches to the appearance of the car and affect the effect of electrophoresis of the car. On the other hand, these hoists have poor stability during the lifting process. When placing the car in the processing tank, it is easy to unhook. It is difficult to complete the re-hooking work in the processing tank, which also wastes time and reduces work efficiency. Utility Model Content
