Galvanized steel wire ropes will cause different degrees of wear after a long period of use. According to the positioning position of the wear, it can be divided into external surface wear and internal surface wear. The wear caused by friction caused by common objects such as galvanized steel wire r Read More

The steel wire rope is a spiral steel wire beam that stretches the steel wire that meets the requirements of the mechanical performance and geometric dimensions according to certain rules. The wire rope is composed of steel wire, rope core, and fat grease. The steel wire rope is first twisted from the multi -layer steel wire, and then the rope core is centered, and a certain amount of stock twist into a spiral rope. In the material handling machinery, the use of improvement, traction, tightening and carrying. The strength of the wire rope is high, the self -heavy, the work is stable, and the work is not easy to break suddenly, and the work is reliable. Read More
