Wire and cable are a large class of electrical products used to transmit electricity, transmit information and realize electromagnetic energy conversion. In modern society, the application of electricity and electromagnetic waves is inseparable from the research and development activities of any scientific and technological development and innovation projects. The generation, transmission and application of electricity and electromagnetic waves must use wires and cables as components for connection and transmission or as winding materials for the host. In fact, all industrial production, transportation, construction engineering and facilities, modern agriculture and scientific research, military equipment or military facilities, space, ocean detection and social life are closely related to wire and cable products. The power supply belongs to the dispatched agencies of the power company, which are distributed in various towns and towns, and mainly carry out line maintenance services, power outage services, meter reading, and electricity fee collection. In the construction process of transmission line erection, the traditional setting-out work is time-consuming, labor-intensive, and the construction progress is slow. When performing line maintenance services, it is usually necessary to use a large number of wires and cables. In order to facilitate operation and improve work efficiency, currently in the process of cable laying and laying construction, after the cables are transported to the site, they need to be laid by cranes. This operation method not only requires the construction personnel to expend a lot of physical strength, but also easily increases the torque of the cable itself or damages the cable insulation layer, which will bring hidden dangers to the safety of power supply in the future.

In the existing cable construction, a pay-off device or a pay-off trolley is generally used for auxiliary cable laying. The cable is usually wound and arranged on a winding roller. However, there is a problem in the existing pay-off device or the pay-off trolley. When the pay-off is stopped, the winding roller cannot stop rotating quickly under the action of inertia, and the redundant cables that do not need to be used are also removed from the winding roller. It falls off and cannot be stopped in time in an instant.
