Buy a second-hand caterpillar crane rammer, about how much money
The use of wire rope in the atmospheric environment, mainly caused by the failure of wire rope is fretting fatigue, at present, the wire rope for the first time in the field of fretting fatigue control measures is the phosphating coating steel wire rope patent technology production, steel wire after manganese phosphating or zinc manganese treatment, wear resistance, enhance the surface of steel wire that is not easy to wear and corrosion fatigue life of the steel wire rope large increase, fatigue life is three times the same structure light steel wire rope (laboratory comparable conditions), can be verified by fatigue test, fatigue test machine if they have on their own to do comparative tests, this test results most credible, steel wire rope life and fatigue life is directly proportional to the fatigue life, long service life of the same proportion of extension.
Phosphating coating of steel wire rope than plain steel wire rope has long service life, lower cost, better stability, phosphating coating of steel wire rope is patent technology production, because the demand is more difficult to buy, to ask the producer of several wire rope, please note in the purchase, purchase invoice must indicate the name of wire rope, such as phosphate coated wire rope to prevent illegal enterprises, infringement of their legitimate rights and interests, in addition, patent products are generally in the rope on the outer packing of a patent spraying label, warranty should be the main technical indicators, such as the phosphating film type and film weight (have an important impact on the phosphate film weight size, wear resistance and corrosion resistance of the service life of the wire rope). For reference only
Take a look at the used car market, a penny a cargo, must see the object and then bid, so as not to be deceived, used car remember not online shopping.A high quality steel wire rope should be used by a crane user. It should be a steel wire rope with long service life and high quality and stability.
