Steel rope GOST 7669-80

The steel rope GOST 7669-80 offered by the Trading House "Gutman - Ukraine" is a double lay rope type LK-RO of design 6 x 36 (1+7+7/7+14) + 7x7 (1+6) (metal core)

According to GOST, it applies to double lay steel ropes with linear contact of wires in strands of type LK-RO with one metal core.

This type of rope is mainly used for hoisting and transport machines and mechanisms, such as excavator ropes, and ropes (cables) used for guy ropes.

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.

 

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.


Thus, steel ropes with a double coil can be used for work under heavy loads, as well as in conditions of increased danger. For ease of reading, the characteristics of the rope are indicated on the tags of the drums (packaging of steel ropes) and certificates.
