Lossless pay-off device

The utility model relates to a lossless pay-off device which comprises a base, a pulley assembly and a lifting hook assembly, and the base serves as a loading main body; the pulley assembly is arranged on the base and comprises a pulley, the pulley is used for making rolling contact with an electric wire, and the middle of the base is hollowed out and used for allowing the electric wire to penetrate through the pulley; the lifting hook assembly is arranged on the base and used for hanging the base at a hanging point. The base is hung at a hanging point through the lifting hook assembly, or the base is placed on the ground, and a wire is paid off through the pulley, so that the problem of friction between the wire and the ground is effectively avoided, the problem that the wire is hung by a fork is also solved, the paying-off efficiency is improved, and manpower resources are saved. 本实用新型涉及一种无损放线器，包括基座、滑轮组件和吊钩组件，基座作为装载主体；滑轮组件设置于基座，滑轮组件包括滑轮，滑轮用于与电线滚动接触，基座的中间镂空，用于供电线穿过滑轮；吊钩组件设置于基座，用于将基座悬挂于吊挂点。通过吊钩组件将基座悬挂于吊挂点，或者将
