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
