Double coiling involves twisting the wire mass into strands with their subsequent transformation into a rope. This type of ropes is put into operation in open space, for example, on construction platforms, metallurgical enterprises and mines. In such stressful conditions, the use of ropes is extremely necessary for the organization of various types of work performed by cranes, lifting mechanisms, excavators, scrapers, and cable cranes. Before buying a wire product, you should familiarize yourself with the regulatory document, which describes the technical characteristics and features of steel rope with a double coil. In order to buy a rope profitably, you need to check its quality very carefully. The selection of a steel wire device also depends on the given operating conditions. At the same time, you should be guided by the provisions of the standard (steel cable, rope guest 7668-80 or others), which provides recommendations for determining the quality level. Thus, steel ropes with a double coil can be used for work under heavy loads, as well as in conditions of increased danger. For easy readability of the rope characteristics marked on the tags of the drums (packages of steel ropes) and certificates, below is a description of the main marked ropes (cables), which is the same for almost all ropes manufactured according to GOST.
