Diese Aufgabe wird gelöst mit einem in Patentanspruch 1 beschriebenen Drahtseil. This object is achieved with a wire rope described in claim 1.
Bei einem solchen Drahtseil ist der Reibwert durch den Anteil der mit Kunststoff ummantelten Außenlitzen einstellbar. In such a wire rope, the coefficient of friction is adjustable by the proportion of plastic coated outer strands.
Durch die Reibwert erhöhende Kunststoffummantelung kann auf ansonsten übliche Reibwert erhöhende, besondere Rillenformen, z.B. Keilrille oder unterschnittene Rundrille, verzichtet werden. Due to the coefficient of friction increasing plastic coating can on otherwise friction coefficient increasing, special groove shapes, e.g. V-groove or undercut round groove, can be omitted.
Gemäß einer bevorzugten Ausführungsform der Erfindung kann der Anteil der kunststoffummantelten Stahlaußenlitzen, der zur Einstellung des benötigten Reib wertes erforderlich ist, auf bis zu 100% erhöht werden, indem sämtliche Stahlaußenlitzen mit einer Kunststoffummantelung versehen sind.
