The take-up and release work in the distribution network maintenance is an extremely important construction link, with a large workload and many risk factors. Especially in the process of retracting and unwinding, there are many and scattered crossover operation points of distribution network lines, and frequent movement during construction. For example: in scenarios such as between highways, communication lines, low-voltage lines, and 10kV lines that cross and cross, there are more cases of crossing and crossing in the work of receiving and releasing lines. At home and abroad, the spanning construction of high-voltage transmission lines is generally realized by airplanes, airships, and towed model airplanes. This method is not suitable for distribution network construction, and the cost is quite high. Due to the low voltage level, small scope of influence, and insufficient attention at all levels for the maintenance and construction of distribution network lines, there is currently no targeted spanning tool for distribution network take-up and release lines.

At present, the following methods are commonly used in the construction of distribution network line maintenance cross-over take-up and release lines: 1. Use ladders to build spanning frames, such as insulating ladders, bamboo ladders, wooden ladders, etc.; 2. Use steel pipes and wooden sticks to build spanning frames 3. Temporarily close the road, and manually drag the line for retraction and release.

When the first and second methods are used, the installation and disassembly of the spanning frame is cumbersome, the labor cost is high, the probability of industrial accidents is high, and it may pose a threat to the safety of passing pedestrians and vehicles. Moving pulleys, and the phenomenon of line jams will occur during the use of the pulleys.
