Slings are used to lift and move heavy or bulky loads that cannot be easily handled by hand. By suspending the load from a sling, riggers can distribute its weight evenly, reducing the risk of injury or damage to the load or equipment. Additionally, slings can be adjusted, to accommodate different load shapes and sizes, making them a versatile and flexible rigging tool. Rigging slings and lifting slings, can be made of cable, chain, rope or webbing,
When connecting 2 or more slings to the loads, sling angles can change from 90° (vertical) to smaller angles (for example 30°) . As the angle changes, the loads that the sling needs to carry, vary. and if the angle from the horizontal gets to be small ( for example 30° or less) , the tension forces that the sling will need to be able to carry, can get to be double than the load weight. Not being familiar with these concepts can result in having an extremely dangerous situation on your hands. So before deciding to casually change the sling angle to gain additional headroom, it is important to calculate loads based on the sling angles and load factors associated with them to make sure we are able to move large heavy loads safely.
Slings are important because they are the elements that make possible to connect the load we want to carry to the devices that will help to carry them. Rigging slings and lifting slings are made of cable, chain, rope or webbing, and are used to safely move large loads.
