Famous brand elevator wire ropes, smooth elevator ropes are outdated and obsolete technology and are not considered famous brands at all

Users hope that the service life of the elevator wire rope will be as long as possible. The longer the service life of the elevator wire rope, the lower the unit cost. A traction elevator wire rope with a long service life can be called a high-quality brand-name product. The difference between a manganese-based phosphate-coated elevator wire rope and a smooth elevator wire rope lies in the type and weight of the phosphate coating on the surface of the rope-making wire, and the type of phosphate coating. And the film weight affects the wear resistance and corrosion resistance of the elevator wire rope, and also has a direct and significant impact on the fatigue life of the steel wire rope. When purchasing a manganese phosphating coated elevator wire rope, you must agree on the phosphating film weight range, such as 15-30 grams / square meter, the heavier the phosphating film, the better the effect, but because of the increased manufacturing cost, the price will be slightly more expensive. It is recommended to stipulate the weight range of the phosphating film in the contract and indicate the product name and the measured value of the phosphating film weight on the invoice to prevent unscrupulous traders from using smooth elevator wire ropes to pass them off as manganese-based phosphating-coated elevator wire ropes. The fatigue life of coated steel wire ropes is three to five times that of smooth steel wire ropes. Manganese phosphating coated steel wire ropes are upgraded products of various smooth steel wire ropes. Smooth steel wire ropes are obsolete products produced with backward technology. When purchasing steel wire ropes, be careful with the production The film weight range of the phosphating film can be determined by the supplier, and other technical indicators can comply with the corresponding national standards or industry standards.
