Two types of pre tension for zinc aluminum alloy steel wire rope

Two types of pre tension for zinc aluminum alloy steel wire rope

There are two commonly used pre tensioning methods for zinc aluminum alloy steel wire ropes: online pre tensioning for zinc aluminum alloy steel wire ropes and offline pre tensioning for zinc aluminum alloy steel wire ropes. The online pre tension of zinc aluminum alloy steel wire rope is directly measured on the rope machine. The online pre tension of zinc aluminum alloy steel wire rope is only suitable for use when the tension of zinc aluminum alloy steel wire rope is small, the tension range is small, and the effect is not very uniform; The offline pre tensioning of zinc aluminum alloy steel wire rope refers to the wide range of use of the tension of zinc aluminum alloy steel wire rope, which is convenient for adjusting the tension of zinc aluminum alloy steel wire rope. The tension adjustment speed of zinc aluminum alloy steel wire rope is fast; The debugging method for another type of pre tension is different.

Special spinning machine wire rope

Special spinning machine wire rope

When it comes to special strand spinning machine wire ropes, we are not surprised that ordinary special strand types of spinning machine wire ropes, such as fan-shaped strands of spinning machine wire ropes, 4V * 39S, 4V * 48S, triangular strands of spinning machine wire ropes, 6V * 19, 6V * 37, and other special strands have many advantages compared to ordinary spinning machine wire ropes. The surface of each strand of special strand spinning machine wire rope is larger than the support surface of the round billet, and during the operation of the spinning machine wire rope, The contact surface of the groove of the drum or rope pulley reduces the contact stress and wear of the spinning machine wire rope; Irregular spinning machine wire ropes have good anti extrusion performance, while spinning machine wire ropes with anti rotation performance, such as fans such as 4V * 39S+5FC and 4V * 48S+5FC.

What is the pre tension of zinc aluminum alloy steel wire rope

What is the pre tension of zinc aluminum alloy steel wire rope

During the use of cableways, zinc aluminum alloy steel wire ropes will have elongated structures, friction wheels, multiple rope hoists for mining, and the application of elevators and elevator engineering equipment. This extension will cause a lot of trouble. How to solve the harm caused by the elongation of zinc aluminum alloy steel wire rope, which is what we call the pre tension of zinc aluminum alloy steel wire rope, that is, before using zinc aluminum alloy steel wire rope, the tensile force of zinc aluminum alloy steel wire rope was tested in advance to eliminate residual stress and the elongation phenomenon of using zinc aluminum alloy steel wire rope. However, the extension of zinc aluminum alloy steel wire rope is inevitable, So we must remain vigilant and observe carefully when using zinc aluminum alloy steel wire ropes.

Deformation problem of fitness equipment steel wire rope

Deformation problem of fitness equipment steel wire rope

Regarding the lifting of fitness equipment steel wire ropes, the customer inquired about the issue of deformation failure. After our team's investigation, this is because the proportion of steel wire between the fitness equipment wire rope and the outer wire of the fitness equipment wire rope is too small. Generally speaking, we recommend that the diameter to outer diameter ratio of the drum and pulley fitness equipment wire rope should not be less than 400MM; Under frequent operation and rapid operation conditions, the ratio of the drum or pulley to the outer wire of the fitness equipment wire rope should not be less than 1200mm, because the outer wire of the metal core (steel core) has better support, so that the fitness equipment wire rope is not easily deformed.

The structure and specifications of the fitness equipment wire rope that we often recommend

The structure and specifications of the fitness equipment wire rope that we often recommend

For the purpose of using fitness equipment wire ropes, we recommend using a structure of 8 * 36WS+IWR, 8 * 31WS+IWR, and 6 * 36WS+IWR. Due to frequent load operations and high strength, fitness equipment wire ropes belong to multi-layer winding on the drum, which determines the characteristics of fitness equipment wire ropes. They have good fatigue and wear resistance, impact resistance, fracture force, and height, In recent years, fitness equipment wire ropes have gradually been compacted. We often recommend the models of fitness equipment wire ropes to customers as 6 * K36WS+IWR and 8 * K36WS+IWR. I do not recommend using fiber core (hemp core) fitness equipment wire ropes.
