What does the inspection of rigging involve?
At present, the wire ropes can detect the broken wires and wear of the wire ropes and display them digitally.
Phosphating coating of steel wire rope (Chinese patent), wire by Mn and Zn Mn phosphating treatment of steel wire, wear resistance and corrosion resistance of fully, are not easy to wear and corrosion fatigue life of the phosphating coating steel wire rope is the same structure of plain steel wire rope 3 times (laboratory comparable conditions), exceeding imports of steel wire rope, phosphating coating steel wire rope are fully replace all kinds of plain steel wire rope, also be replaced after plating the first pull layer thin zinc galvanized steel wire rope used (through salt spray test the corrosion resistance test), long service life, use lower cost, better quality stability and reliability.
The crane used in atmospheric environment, preferably manganese phosphide coating, steel wire rope, heavy corrosive environment, preferred hot-dip galvanized double phosphating steel wire rope, priority wire rope in sea water. Please note that at the time of purchase, in the purchase invoice must indicate the name of wire rope, such as phosphate coated wire rope or 316 stainless steel wire rope, prevent illegal infringement of their legitimate rights and interests of enterprises, to counterfeit products in addition, patent products are generally in the rope on the outer packing is patent spraying mark, warranty book should be the main technical indicators, such as the phosphating film type and weight (film has an important influence on the weight of phosphating film size, wear resistance and corrosion resistance of the service life of the wire rope, for reference only)
The stainless steel wire rope is mainly made of 304 or 316 stainless steel. The anti-corrosion effect is excellent, but the price is expensive4. carbon coated steel wire rope, wire rope based on polyethylene, polypropylene or nylon outer coating5. smooth wire rope, short service life, the market demand is declining, the phosphating coating steel wire rope round out.
Galvanized steel wire rope, including hot galvanized and galvanized two kinds, galvanized zinc layer is thick corrosion resistant ability is strong, the thickness of zinc in grams / square meter said.
