Not easy.
This kind of steel wire rope, whose professional name is called anti-rotation steel wire rope, is a multi-layer stranded steel wire rope. The inner and outer strands of this kind of steel wire rope adopt opposite twist directions to achieve the purpose of anti-rotation.
The wire rope will have residual twisting stress and will tend to rotate when receiving tension. Rotation will cause the two wire ropes to become entangled with each other, affecting the lifting operation. Anti-rotation wire ropes are suitable for tower cranes with relatively large heights to prevent the wire ropes from becoming entangled with each other. Commonly used types of steel wire ropes for cranes include phosphate-coated steel wire ropes, galvanized steel wire ropes, stainless steel wire ropes or plastic-coated steel wire ropes. They are used in atmospheric environments. The manganese-based phosphating-coated steel wire ropes produced with patented technology have the longest service life. Anti-corrosion is preferred in heavy corrosive environments. Hot-dip galvanized-phosphating double-coated steel wire rope with outstanding capabilities.
