35W * 7 and 35W * K7 steel wire ropes are two common types of steel wire ropes, both of which are composed of many small steel wires. They have many similarities and some differences.
Firstly, both 35W * 7 and 35W * K7 steel wire ropes have high strength and durability, capable of withstanding heavy loads and repeated use. Whether it is as a lifting rope or a fixed rope, they are competent.
Secondly, their difference lies in the number and arrangement of internal steel wires. The 35w * 7 steel wire rope consists of 35 steel wires with an outer diameter of 1.5-8mm, arranged in a manner of 1+6+12+12+6, with one steel wire in the center and the other steel wires around. The 35W * K7 steel wire rope consists of 45 steel wires with an outer diameter of 1.0-11mm, arranged in a way of 1+6+6+6+6+6+6+12, with one steel wire in the center and the other steel wires around.
In addition, 35W * K7 steel wire rope has higher torsional stiffness and better fatigue performance compared to 35W * 7 steel wire rope, making it suitable for use in more complex working conditions.
Overall, both 35W * 7 and 35W * K7 steel wire ropes are excellent rope products with high strength and durability. However, their steel wire quantity and arrangement are different. Therefore, selecting suitable steel wire ropes under different working conditions can better leverage their advantages.
