It is very necessary to select the suitable wire rope to improve the production efficiency. Under specific service conditions, the selection of wire rope should consider the following factors:
Structure selection: the service life of wire contact wire rope is longer than that of point contact wire rope.
Generally, it is 1-2 times of the point contact wire rope; when the compacted strand wire rope bears the load, because of the large contact area between the steel wires, its stress is much smaller than that of the line contact wire rope, so the service life of the compacted strand wire rope is longer than that of the point contact wire rope, which is generally 2-3 times of the point contact wire rope.
Strength: under the condition of ensuring the safety factor of equipment, the steel rope with suitable strength level shall be selected.
Non rotation performance: multi strand wire rope, three strand wire rope and four strand wire rope have good non rotation performance.
Fatigue resistance: when bending fatigue is the main cause of wire rope damage, wire rope composed of small size steel wire, wire contact wire rope and compacted strand wire rope should be selected.
Wear resistance: when it is determined that wear is the main cause of wire rope damage, the relatively thick outer steel wire rope, compacted strand wire rope and the same direction twisted wire rope should be selected.
Anti deformation performance: steel core wire rope and compacted strand wire rope should be selected when extrusion deformation is the main damage form of wire rope.
● corrosion resistance: galvanized steel wire rope, sealed steel wire rope, plastic coated steel wire rope, steel wire rope coated with oil on the surface shall be selected in the application occasions where corrosion is the main damage form of steel wire rope.
Impact performance: steel core wire rope shall be selected.
High temperature resistance: steel core wire rope shall be selected.
