A sling is a form of equipment that is used to lift heavy objects. You can use a lifting sling to hoist heavy objects that you can lift by hand. The sling is attached to lifting equipment, such as a crane. Additionally, these slings can be constructed from different types of materials.
In today’s article, we are going to look at wire rope slings and their applications. This type of lifting sling is ideal for hoisting tasks because of its strength, flexibility and durability.
Why Choose a Wire Rope Sling?
Wire rope slings are reasonably priced and are excellent at stabilising the load that needs to be lifted. Other benefits include:
- They are resistant to abrasion
- They can’t be crushed easily
- Won’t corrode easily
- Resistant to rotation
What to Take into Consideration
If you need to purchase a lifting sling, there are certain features you need to consider such as:
- The length of the item
- The size and volume
- The direction and type of lay
- How the wires are finished
- The grade of the rope
- What material the cord is made of
Each type of wire rope sling has a maximum breaking strength and load limit, that shouldn’t be exceeded.
Carry Out an Inspection Before Using it
Lifting heavy objects can be dangerous. It’s extremely important to inspect the sling before every use. Anyone that works with the sling should be taught how to inspect the sling. Look for the following:
- The slings workload limit capacity
- How long the sling is
- Look for deformities
- General damage and wear and tear
- Make sure all the pieces are there and in working order
- Wires that are frayed or look out of place
- Bent hooks
What are the Different Kinds of Lifting Slings and What are they used for?
There are many different types of lifting slings and each of them is used for a different purpose.

Common Uses for Lifting Slings
Lifting slings are very versatile and can be used for the following purposes:
- Mountain climbing: Webbing slings are often used for climbing mountains as a stabilisation device. They can be secured around trees or rock structures to protect the climber from falling as they ascend.
- On your boat: Boats are incredibly heavy and require a lot of work to get them in and out of the water. Some boats need to be docked on land. To accomplish this task a special lifting sling is needed.
- Towing a car: Webbing slings are perfect for towing other large vehicles, such as diggers, trucks, caravans and horseboxes. The slings provide extra power should the vehicle be stuck in the mud or snow.

- Tree surgeons: People that chop down trees or do tree maintenance often use slings to keep themselves safe, when they work at great heights. Slings could even be used to lift and lower cut branches safely.
- Laying pipes: Pipes are extremely heavy, so plumbers use lifting slings to pick them up and then lower them into the correct position.
- The construction industry: Building materials and wooden beams are lifted into place by cranes using lifting slings.
- Heavy machinery: The only way to move heavy machinery is by using lifting slings and a crane
- Telecommunications industry: They use lifting slings to install pylons, poles and other items
- Aeroplanes: Slings are used to lift and transport parts of the aircraft. This system is also used to replace faulty parts.
Lifting slings can be used in many different ways. Almost every business that requires heavy lifting needs to have slings available. Additionally, there are different types of lifting slings, so it’s important to choose the correct sling for the job. If in doubt, contact an expert for advice.
