Proper Maintenance And Storage Of Lifting Slings

Proper Maintenance And Storage Of Lifting Slings

If you can adequately take care of your lifting slings, you will be surprised about the extended service life of the product. It can help you with a better return on your investment. When you do not use any sling protection during operation, you create every possible chance of injury or tend to drop the load.

Rope wire slings, chain slings, round slings, metal mesh slings, web slings, and synthetic ropes are used to lift, position, or move any load efficiently. But the lifting slings that you choose will depend on the environment and its application.

Proper storage and maintenance can maximize the life of your lifting slings. Here are some of the ways you can prolong life.

  • Avoid extreme temperatures: No matter what kind of lifting slings an individual uses, every sling is prone to damage. When you expose the lifting slings to extreme temperatures, they reduce the performance as their strength diminishes. While some materials like the wire rope, wire mesh, or alloy chain can tolerate severe weather, they tend to become soft and brittle when you try to use them in extreme temperatures for an extended period.
  • Be aware of any chemically active environments or chemical exposures.: Sometimes the process of galvanizing can add corrosion resistance to the metal surface. However, when you are trying to coat or dip the material, you need to understand the acidic or alkaline property of the liquid in which the lifting sling would be submerged. Polyester or nylon are generally susceptible to these chemical damages. Therefore make sure there are no chemically active components near the lifting sling.
  • Avoid prolonged exposure to UV light and sunlight.: The synthetic material provided on the different kinds of lifting slings can degrade if you expose it to long-term ultraviolet light or sunlight. The bright colouration also tends to fade or become dull in appearance. When you perform regular inspections of the lifting sling, look for any faded areas or stiff areas.
  • Avoid rough surfaces and edges.: It does not matter whether the sling is made of nylon, polyester, or steel. If you do not provide proper protection or protection, then it can experience holes or punctures. In the case of metal mesh, it can distort the fittings or broken wires. While in the case of alloy chains, it can cause distortion, crushed fittings or gouges. The wire rope can experience damaged fittings and broken cables, while the synthetic slings can have snags and cuts.
  • Keep your slings free from debris.: When you are not using the rigging equipment for the lifting sling, ensure that you clean it properly and organize it well. If you expose the lifting slings to continuous dirt or moisture, your lifting sling would prematurely break down.

Also, look for the smallest particles like stones or dirt inside the lifting slings while you clean them, as they can cause abrasion or fiction while causing the slim to wear out from inside.

How can you store and organize the sling?

When you are organized, you can find the right equipment at the right place. While you manage your rigging gears, it would be easier for you to find the right equipment that you need. Also, the best way to do this is to prepare a periodic inspection.

It would be best if you stored the sling away from extreme temperatures, mechanical devices, chemicals, and moisture. Ensure that you keep up the slings off the ground so that they are not crushed by any vehicles or fork trucks during operation.

Here are some other factors that you must keep in mind while you store the lifting slings.

  • Make sure that you keep your lifting slings in a dark, dry, and relaxed environment.
  • Avoid exposing your lifting slings to extreme cold or hot temperatures. If done, then your lifting slings wood loses its strength to work.
  • Keep your lifting slings clean and avoid any moisture, dirt, or dust on their surface. These can degrade the quality of the material over time while shortening the longevity of the product.
  • You need to be aware of the environmental temperatures.
  • In case of any problems, make sure that you contact the manufacturer and not any other person.

Conclusion

When you know how to take care of your lifting slings, it will increase the life expectancy of the equipment. It can provide you with the best return on your investment. Therefore make sure that employees regularly inspect and maintain the slings and the rigging equipment.

Create a schedule for sling inspections

You can make this schedule based on-

  • The frequency of your wire rope sling use
  • The type of your lifts
  • The severity of regular service conditions

Daily inspections: A visual inspection is a must every day, as the person using the sling has to identify the signs of deterioration. Any minor damage may weaken the wire rope sling. Thus, the user needs to check out defective wires, crushing potentials, corrosion, and faulty attachments.

Yearly inspections: You can do the inspection annually and make sure that you have checked every part of the sling, including the fittings, end attachments, and splices.

Is it time to replace your old slings?

After inspection, you may have found some signs of damages. Still, you cannot confidently choose between repair and replacement of those damaged slings.

  • Deteriorated wires- When you are using single-part slings, 5 damaged wires in a strand indicate the time for a replacement. Similarly, while there are 10 randomly damaged wires in a rope lay, you have to replace the multi-part sling.
  • Metal loss- Outer diameter of wires may have wear and tear indicating the loss of metal.
  • Bent and cracked end attachments of wire rope slings
  • Severe rope corrosion denotes that you must replace your slings. However, light rusting simply reduces the strength of your slings.
  • Bent hooks- The standard throat opening is 15%, and while it is more than this limit, you have to take steps.

How will you dispose of your damaged slings?

You have to cut the fittings and eye of the sling and then label them properly to avoid using them mistakenly. You must not reuse those slings in any way.

Overall, we can say that proper inspections prevent you from using damaged wire rope slings. It is best to hire professionals to inspect those slings. You can avoid costly repairs by checking and maintaining wire rope slings throughout the year.

You can make your slings long-lasting with thorough maintenance and care. Moreover, you must learn the right ways of storing those slings while they are not in use. Keep them away from heat, liquids, sprays, and corrosion. You may use your wire rope slings for several years.

Sling Protection

Any sling that bears on a sharp edge or corner needs protection. Synthetic slings (web slings and round slings) need it most, because polyester and nylon cut and abrade easily.

  • Wear pads
  • Corner pads and corner protectors
  • Sleeves and covers
  • Reinforced eyes

Fit protection wherever the sling touches the load edges, eye bolts, hoist rings, the crane hook or a shackle.
