The correct using of stainless steel wire rope is to ensure that the life of the important guarantee, and in the practical application process, Stainless Steel Wire Ropes due to the carelessness of the operator, there is no standard operation caused by the use of wire rope fatigue, resulting in a certain security risk.
The first is bending fatigue, stainless steel wire rope repeatedly through the pulley or reel scratching, numerous bending, easy to make steel wire fatigue, toughness decreased, eventually leading to broken wire. And fatigue broken wire appears in the most severe bending of the outer wire. Often, Stainless Steel Wire Ropes the appearance of fatigue broken wire means that the stainless steel wire rope is already close to the late use. The results show that the bending fatigue life of the stainless steel wire rope is closely related to the D / d ratio (ie, the ratio of the diameter D of the reel and the diameter of the wire rope). The safety factor and the rope structure are closely related.
The second is tensile, twisting and vibration caused by fatigue, stainless steel wire rope in the start and start of the brake, bundled wire rope before and after the load, Stainless Steel Wire Ropes the tensile stress will cause metal fatigue. In addition, stainless steel wire rope is often subject to distortion and vibration is also the cause of fatigue. The principle of fatigue damage is under the action of stress, Stainless Steel Wire Ropes the first fine steel wire surface due to a variety of slip to form the initial crack, and then crack tip under the action of shear stress repeated plastic deformation, so that crack propagation until the fracture. Its fatigue caused by the broken wire generally flat, mostly in the surface of the wire, and very regular.
Regulate the operation of stainless steel wire rope is fundamental, Stainless Steel Wire Ropes we can control the above list of factors, to avoid the incorrect use of methods, so as to effectively prevent the use of stainless steel wire rope fatigue, to extend the service life to create the conditions.
Transport: loading rope rope can be used to wear rope rope rope hole or steel pipe into the shaft hole, and then set the rope at both ends of the pipe, is prohibited from the high directly rolling down, you must use the transition springboard slowly slide down Or with a crane hanging, the ground handling, Stainless Steel Wire Ropes if you need to pry carry, do not directly pry on the surface of the rope, so as not to cause the surface of the rope crushing long-distance transport need to cover the cover, to prevent the impact of rain caused by the use of corrosion.
Daily storage: stainless steel wire rope storage, should be placed in a ventilated and dry room, to prevent direct sunlight and hot air baking; such as must be on the outside, should be placed on the higher ground, covered with rain cover. Place the ground above the general height of 300mm or more.
