The article describes the main types of steel wire ropes, their structure, the materials which they are made of and modern ways to increase their operating characteristics. There are also explores the forces occurring in a double lay rope with organic core, produced the selection of the rope based on forces acting on the polyspast. Taking into account the structure of the steel rope, is calculated the maximum equivalent tension in it, and this value is compared with the maximum allowable tension value in accordance with the labeling group of rope. The calculation scheme of the rope is a rod (the core) working on tension, and a spring (strands) working on torsion, bend and shear, the axes of which is coincide with the axis of the rod. We made calculations with different values of the applied load and came to the conclusion that in the rope occur tensions longer than tensions given in the GOSTs. Therefore it is necessary to increase the strength of the rope without changing the diameter of its strands in order that the rope does not lose its flexibility. It is one of the main directions in the study of the ropes nowadays.
