CONSTITUTION: A winch of multiple drums for multiple structures includes many rows of drums(100); an input element; a driving device(200); a clutch(300); a level winder(400) and a brake(500). Many rows of drums are combined to shafts(110) combined to a main body(10) in multiple layers with bearings(102) to be rotated. The input element is combined to input ends of shafts of each layer. The driving device drives shafts. The clutch connects and disconnects power between the input element and each drum. The level winder guides a wire to be wound and led to each drum. The brake stops each drum. A vertical wire guide roller is connected to a lever of the level winder to adjust a width. A spring tightens the level winder. Therefore, an operation to lead and collect all signal cables is operated easily when many pieces of cables are wound separately. The level winder passes a uniform diameter of the wire, and the wire is inserted and stripped off after opening and shutting easily a vertical wire guide roller if necessary.
