Galvanized steel wire rope 1.2MM 7*7 bearing 15kg 4000m/roll

Steel wire ropes are mainly used in transportation such as hoisting and hauling that require high-strength wire ropes.

The steel wire is made of high-quality carbon steel, which can reach high strength after repeated cold drawing and heat treatment. Steel wire ropes twisted from galvanized steel wires can be used in workplaces such as wet or open air environments to enhance anti-rust performance.

Steel wire ropes are standard products in various industrial countries, and their diameter, number of strands, number of wires per strand, tensile strength and sufficient safety factor can be selected according to the needs of the application.

Its specifications and models can be found in relevant manuals. In addition to the wear of the outer layer of the steel wire, the steel wire rope is gradually broken mainly due to metal fatigue caused by repeated bending when passing around the pulley and the drum.

Therefore, the ratio of the diameter of the pulley or drum to the wire rope is an important factor that determines the life of the wire rope. If the ratio is large, the bending stress of the steel wire is small and the service life is long, but the mechanism is huge.

The appropriate ratio must be determined according to the application.

Steel wire rope shall be scrapped when the degree of wear and corrosion of the surface layer or the number of broken wires in each twist exceeds the specified value.
