We are not unfamiliar with profiled strand wire ropes. Common profiled strand wire ropes, such as fan-shaped strand 4V * 39s, 4V * 48S, triangular strand 6V * 19, 6V * 37 and so on, have many advantages compared with ordinary round strand wire ropes,
Firstly, the surface of each strand of special-shaped strand wire rope is larger than that of round strand. During the operation of wire rope, the contact surface with drum or pulley groove increases, which reduces the contact stress and wear of wire;
Secondly, the special-shaped strand wire rope has good anti extrusion performance, such as 4V * 39s + 5FC, 4V * 48S + 5FC, which also has anti rotation performance;
Thirdly, the density coefficient of wire rope is large, so the breaking force of wire rope is also large, which is more than 20% higher than that of round strand wire rope of the same specification;
Special shaped strands such as 6V * 19 / 6V * 37 / 6V * 34 / 6V * 21 are widely used in the field of coal mine engineering, such as shaft hoisting, inclined shaft hoisting, and others such as electric shovel hoisting and blast furnace hoisting. Special shaped 4V * 39s + 5FC sector strand wire rope is often used in busy lifting equipment (such as tower crane, port hoisting, etc.)
