[0002] Busbars are key equipment used for conductor connections in power transmission and transformation systems. They are mainly used in substations and power plants for connecting transmission lines to transformers, for power line jumpers, and for high-current DC de-icing devices. They can replace traditional rectangular busbars or steel-cored aluminum stranded wires. "Large span" refers to the large distance between two support points (such as post insulators or frames) of the busbar.

[0003] Currently, busbars require hoisting before installation. Due to the long length of the busbars, horizontal hoisting is used. During hoisting, it is necessary to ensure the symmetry of the positions of the hoisting tools on both sides to improve the stability of the busbar hoisting. However, the existing hoisting tools are inconvenient to adjust, requiring measurement and marking before locking the position, which is inefficient and needs to be improved. Utility Model Content
