1.Tight wire tensioner selection (1) elevator, aviation wire rope, etc. should use the corresponding wire rope (2) high-rise building tower wire rope, etc. should use the corresponding special wire rope (3) tight wire tensioner without elevator tensioner high-speed crane, pile driver, drilling rig, electric shovel, excavator and other mechanical wire rope need to wear-resistant, fatigue-resistant and impact-resistant. They can be used in high temperature environment 6 * 29Fi or 6 * 36SW structure wire rope (4) for the next operation or equipment that requires large breaking load, metal rope wire rope (5) wire rope used for transportation, ships, fisheries, bundling wood, etc., requires corrosion resistance and flexibility, optional 6 * 19,6 * 24, 6 * 37 A grade galvanized wire rope other structures. In addition, should be used according to the load and the specified safety factor to choose the selected wire rope tensile strength. Blindly pursuing high strength is not appropriate.
