What effect is the cord in the crane wire rope?
The steel wire rope is made up of a piece of wire rope. Using the IWS or the IWR. Steel wire rope is wear-resistant, compressive and has high service life, the breaking tension is relatively high and the softness is relatively low. Because of the cause of wear-resisting pressure, the steel wire rope is suitable for the crane or the hoist. Steel core wire rope price is hemp core wire rope relatively a bit higher, but considering the service life of the wire rope and the tension will be relatively a bit better, so in accordance with the overall performance for the cost of steel core wire rope is relatively low.
New hemp rope core generally contain 12% ~ 15% of the oil, and scrap steel wire rope in the loss of the largest part only contains 2.4% of fat, on the same piece of wire rope, even without pulley still oil containing 12.7% ~ 14.5%. The experiment shows that the broken wire of the coated steel wire rope is about half of the non-oil. The initial oil content of a wire rope can only last 40 percent of the life span, and then it increases dramatically if not refueling. The second is the use of the steel wire rope with poor environment and relatively low relative motion, which can choose the special wire rope such as galvanized and aluminized aluminum. These cables are exposed in the atmosphere to galvanized or coated with aluminum hydroxide and aluminum hydroxide films, which effectively prevent corrosion of wire rope
Take the hemp core material: Hemp core material with general of hemp fiber is used in the basic same, hemp core function is to store oil, make the oil on the surface of the steel wire rope to achieve lasting complement, make the steel wire rope is durable for a long time. It is essential to oil the wire rope which is constantly in motion.
Rope core is the inner part of the steel wire rope, metal core and fiber core, function as supporting and reduce the pressure between stocks, mainly fiber rope core also plays a role of lubrication, corrosion protection and oil storage. The fiber core wire rope is made up of a fiber rope. I'm going to use the letter FC.
