How to extend the service life of wire rope

To extend the service life of the wire rope, you can start from the following aspects：

I. Rational selection and use

1. Selection of high-quality wire rope：
   • Prefer wire contact ropes, whose life is usually 1~2 times longer than point contact ropes.
   • Ensure that the steel wire material of the wire rope is of high purity, good fatigue resistance and flawless appearance quality.
2. Correctly matched pulleys and wire ropes：
   • Pay attention to the material, hardness, shape and size of the groove and processing accuracy of the pulley used with the wire rope to reduce friction and wear.
3. Avoid overloading：
   • Prohibit overload lifting to prevent the wire rope from accelerated wear and tear or breakage due to overloading.

II. Standardised operation and maintenance

1. standard operation：
   • Prohibit crooked pulling and slanting hoisting to prevent the wire rope from swinging and shaking, in order to reduce all kinds of wear and tear arising therefrom.
   • In the process of use, to avoid the wire rope by sudden impact or violent vibration.
2. Timely tampering of wear parts：
   • For wear and bending serious parts, timely tampering treatment, in order to extend the service life of the wire rope.
3. Regular inspection and replacement：
   • Regularly check the wear and tear, broken wire, deformation and corrosion of the wire rope, and find timely replacement of problems.
   • For the service life or the existence of potential safety hazards of the wire rope, should be replaced immediately.

III. Protection and maintenance

1. Preventing corrosion：
   • Prevent the wire rope from contacting with high-temperature objects or baking at high temperatures to avoid annealing of the wire.
   • Prevent the wire rope from contacting with acid, alkali, salt and water to avoid corrosion.
   • For wire ropes that need to be exposed to harsh environments for long periods of time, anti-corrosion measures such as galvanising or injection moulding are recommended.
2. Lubrication and maintenance：
   • Regular lubrication and maintenance of wire ropes to reduce friction and wear and tear.
   • According to the use of the environment and working conditions to choose the appropriate lubricant, such as high-temperature environment can be used for high-temperature lubricants, wet environment can be used for waterproof performance of the lubricant.
3. secure：
   • When the wire rope is no longer in use, it should be properly stored to avoid direct contact with the ground and subjected to distortion, abrasion and other impacts.
   • Storage should be dry and ventilated, avoid direct sunlight and humid environment.

lifting wire rope performance

1. Optimisation of the twisting process：
   • Reasonable choice of wire rope twisting form and twisting distance, in order to reduce the stress concentration effect, improve the fatigue life of the wire rope.
2. Improve the mechanical properties of steel wire：
   • Through the optimisation of the chemical composition of the steel wire and heat treatment process, improve the tensile strength and toughness of the steel wire, so as to extend the service life of the wire rope.

In summary, to extend the service life of wire rope need to start from the reasonable choice and use, standardised operation and maintenance, protection and maintenance and improve the performance of wire rope and other aspects. Through comprehensive measures, can significantly improve the service life and safety of wire rope.
