Un di\u00e1metro insuficiente genera una fuerza de rotura insuficiente, lo que puede provocar la rotura del cable o la fractura del mismo, causando la ca\u00edda de la carga, da\u00f1os en el equipo y accidentes laborales. Por otro lado, un di\u00e1metro excesivo aumenta la carga sobre los tambores, poleas y mecanismos de elevaci\u00f3n, incrementa los costos de adquisici\u00f3n del equipo y agrava el desgaste de los mecanismos.
