Since only manpower can be used for pulling and traction type wire collection and pay-off, the construction difficulty is great under the influence of the environment and terrain, and the degree of wear and tear on the cable is more serious during the process of manpower traction, which does not meet the safety needs of the personnel and equipment during operation. At present, the distribution network generally uses wire collection and pay-off vehicles for wire collection and pay-off operation. For example, the patent with the publication number CN218754312U discloses a distribution network wire and cable collection and pay-off vehicle.
