Where is 35wx7 non rotating wire rope used?

Brief introduction of 35wx7 non rotating steel wire rope

Non rotating steel wire rope, also known as multi-layer strand steel rope, is mainly used for 12mm, 13mm, 14mm of tower crane (tower crane, tower crane) and 12mm-22mm of truck crane. Gantry crane 12mm-28mm, electric hoist 12mm-28mm, some are also used for cableways, and a large part is used for ports, such as Rizhao Port, Shanghai port, Ningbo port, Dalian port, Tianjin port and other first-class wharf large and small cranes, which are basically dominated by non rotating steel wire rope. 18 * 7 and 35W * 7 account for half respectively, but in the later stage, 35W * 7 must be the main one. After all, the cost performance is much higher than 18 * 7, although the unit price is a little higher.

Many users call non rotating steel wire rope non winding steel wire rope and non twisting steel wire rope. It is mainly due to the non rotating rope production process (please check the steel wire rope production process, non rotating wire matching method and twisting process for details). The inner and outer strands are twisted in the opposite direction to counteract the rotating force. 18 * 7 and 19 * 7 are also called micro rotation and semi rotation. 35W * 7 is a real non rotating steel wire rope, and its density is higher than 18 * 7 and 19 * 7. However, due to the very high requirements for the twisting process of rope strands. 35W * 7 ropes are basically made of 72A, 82B and T9 materials, most of which are 82B, and the strength is basically 1870n / mm21960n / mm2.

Non rotating wire rope

Non rotating steel wire rope is mainly used for wharf crane, construction tower crane, crawler crane, truck crane, mining winch, crane electric hoist and other special and important purposes.

An important feature of non rotating steel wire rope is that the repeatability of steel wire rope is improved and becomes soft; The recoil force is very small and will not form winding knots; Non rotating performance is improved. Therefore, the non rotating steel wire rope is also convenient to install, safe and reliable to use, with uniform stress and stable operation. It is not easy to break the wire during use. Even if the wire is broken, it will not tilt up and still lie on its original position, so as not to scratch the rope sheave or drum and affect the normal work of other steel wires. This kind of crane has good load-bearing capacity, flexible loading and unloading capacity of oil shaft, tower shaft, vertical shaft and other industries, and can be used in various industries, such as oil shaft, vertical shaft, steel wire, lifting shaft and so on.
