Wire rope is refers to the use of multiple root or more shares of fine wire into flexible rope, wire rope is composed of multilayer wire twist into shares, centering on the rope again, by a certain amount of shares twist around into a spiral line.In the material handling machinery for ascension, traction, taut and bearing.Wire rope of high strength, light weight, stable work, is not easy to suddenly broken, reliable work.
Various layers of steel wire rope, the state and the shape is different also, so we in the choose and buy when how to judge the stand or fall of wire rope?
1. Specific gravity: that is, the higher the weight of wire rope of the same diameter, quality also is relatively better.That, of course, also want to see material pledge, some weight reached, wire rope and material not, it will affect the quality of the products.
2. Cut the rope after micro loose are of good quality and length of lay relatively long rope quality is better than a short lay length;The believe that everyone can understand, cut the rope, the more does not mean that the screw loose a compiled more strong, natural quality also will be better.
3. In the process of purchasing wire rope should also note that several factors, such as requests for quotation when must get wire rope type at all:
(1) the steel wire rope structure: how much how much stock of wire, such as 18 x 7 is 18 stocks 7 per share of wire
(2) the diameter of wire rope: there are many customers inquiry: six, eight is 6 mm, 8 mm
(3) the wire rope usage: wire rope application field is very wide, say wire rope usage at the time of purchase can have twice the result with half the effort
(4) steel wire surface treatment: treatment over the surface of steel wire rope, smooth surface, galvanized, plastic coated, and stainless steel
(5) purchase quantity: wire rope can be inquiry, kg, and tons of rice
(6) other requirements: including what is the raw material, the tensile strength of steel wire, electric galvanized or hot dip galvanized, rope core requirements (hemp core or steel core), plastic coated wire rope should tell itself diameter and the diameter of the plastic coated later, as well as the factory delivery time and so on.Also for the production license and wire rope quality assurance certificate (certificate).
