How to wire the electric wire rope hoist

Users need high-quality wire ropes, which are wire ropes with long service life and highly stable and reliable quality.

The main reason for the failure of the wire rope used in the atmospheric environment is fretting fatigue，At present, the world's wire rope field to take prevention and control measures for fretting fatigue is the phosphate coated wire rope produced by patented technology,The rope-making wire is treated by manganese phosphating or zinc-manganese, and the wear resistance and corrosion resistance of the steel wire surface are improved, and the fatigue life is greatly increased by not being easy to wear and corrosion, and the fatigue life is three times that of the smooth wire rope of the same structure,The comparison of test values has reached a staggering four times, which can be verified by fatigue testing,If you have the ability to fatigue life, you can do a comparative test by yourself, the test results are credible, and the service life of the wire rope is proportional to the fatigue life,If the fatigue life is long, the service life of the wire rope will be extended in the same proportion, the use cost will be lower, and the stability will be better.Because the supply exceeds demand, phosphating coated wire rope is currently difficult to buy, and it is necessary to ask a few more wire rope manufacturers.

Electric wire rope hoist generally uses small-diameter wire rope, and it is recommended to use manganese-based phosphate coated wire rope.

The unit cost of wire rope can be calculated in this way, and the cost of purchasing wire rope is divided by the number of days of use, that is, yuan/day.Or divide the purchase cost of wire rope by the tonnage of lifting goods, that is, calculate yuan/ton of goods. If it is container transportation, it can be calculated as RMB/Box.Based on this data, it is more cost-effective to compare the type of wire rope used.Cheap wire rope does not mean low cost of use, and expensive wire rope does not mean high cost of use,It is recommended to use manganese-based phosphate coated wire rope, which is a patented technology that can be used in the production of various types of wire ropes,There are already enterprises that produce this kind of wire rope, which is very suitable for crane cranes, especially frequently used cranes, such as gantry cranes for container loading and unloading in ports.The use time of the pile driver wire rope is very short, it is recommended to use the manganese phosphate coated wire rope, which can soon verify that its service life is several times that of the smooth wire rope of the same structure, and the phosphating film can be required to be thicker when purchasing to ensure the protective effect of the phosphating film on the wire rope.

Commonly used wire rope varieties include phosphate-coated wire rope, galvanized wire rope, stainless steel wire rope or plastic-coated wire rope.The manganese phosphate coated wire rope produced by the patented technology has a longer service life, and the hot-dip galvanized-phosphated double-coated wire rope is preferred in heavy corrosive environments.

The phosphate-coated wire rope produced by the patented technology preferentially adopts manganese or zinc-manganese phosphating, compared with the smooth wire rope production process, but the wear-resistant phosphating treatment process of the wire rope is increased,The wear resistance and corrosion resistance of rope wire are greatly improved, and the wire is directly twisted after cold drawing after phosphating.At present, the fatigue test data show that the fatigue life of phosphate coated wire rope is about 3-4 times that of the same structure smooth wire rope (under comparable conditions in the laboratory), and with the study of wear-resistant phosphate formula, there is a possibility of significant improvement.Manganese phosphating is wear-resistant phosphating, which can solve the problem of wear and tear in the use of wire ropes, and smooth wire ropes are being eliminated, because phosphating coated wire ropes are in short supply, which is currently more sought-after.

The price of purchasing phosphate coated wire rope is higher than that of smooth wire rope, but the unit cost of use is lower than that of smooth wire rope.The current test data proves that the fatigue life of phosphate-coated wire rope is 3-4 times that of smooth wire rope, and the service life of wire rope is proportional to the fatigue life,According to the approximate price of the current wire rope market, the price of manganese phosphate coated wire rope is about 1.4-1.6 times that of smooth wire rope, and the service life extension is much higher than the price increase, so the average daily use cost of phosphate coated wire rope is only 30-45% of that of smooth wire rope, and the use cost is lower and more cost-effective.
