The invention discloses an auxiliary lifting tooling for cable mounting and a cable paving system. The auxiliary lifting tooling comprises a main bracket, a lifting driving part, a fixed pulley and ahoisting part, wherein the main bracket is provided with a bearing end; the lifting driving part is arranged on the main bracket; the fixed pulley is arranged on the bearing end; the hoisting part ismounted on the fixed pulley; one end of the fixed pulley is connected with the lifting driving part; a binding part is arranged at the other end of the fixed pulley; and the binding part is used for fixing a to-be-lifted cable. Firstly, the main bracket is moved to the position beside a cable bracket, then, the cable is fastened through the binding part, the lifting driving part is started to windthe hoisting part, through rotation of the fixed pulley, the hoisting part gradually drives the cable to rise to the position close to the cable bracket, then, the binding part is released, and the cable is pushed onto a hoop on the cable bracket and is fixed, so that cable mounting efficiency can be improved, construction cost is reduced, body potential safety hazards of construction personnel are relieved or eliminated, and the cable is prevented from being damaged.
