A sling is an element that is used to raise or raise a body heavy. The concept comes from the English word sling.

According to what is detailed in the dictionary of the Royal Spanish Academy (RAE), the sling consists of a rope that has hooks. To understand the notion, therefore, it is convenient to focus on these terms.


Slings are useful for the development of rescues at height.

Analyzing a sling

We used to say that a sling is a rope. This word comes from Hispanic Arabic mabrum, in turn derived from classical Arabic mabrūmah (which can be translated as “Twisted”). Ropes are ropes that have a significant thickness and are characterized by their resistance.

A hook, meanwhile, is a corvo device whose ends, or at least one of them, usually end in a point. By design, the hook allows you to hang or hold something.

How does it work

It can be said that a sling is an intermediate article that links two other parts. It is a tape finished in a loop that has a pulling or lifting hook.

The sling can be made of steel, polyester, nylon, or other materials. The important thing is that it is resistant, elastic and flexible to have a good load capacity. Usually its resistance is associated with the material and the width of the rope.

The operation of the sling is simple. The noose must be hooked to what is intended to be lifted, dragged or secured; therefore, at the other extreme there must be something or someone capable of carrying out or withstanding a force.


With a sling it is possible to tow a vehicle that got stuck in the ground.

Sling Uses

Slings are often used to mobilize a vehicle that got buried or trapped in soft ground. In these cases, the sling links the locked car with another that can pull it.

Another frequent use of the sling appears in the field of mountaineering. The sling makes it possible to create a assurance meeting or anchor point, protecting mountaineers against eventual falls.

In addition, the sling is useful at the time of a rescue, since it allows the person who fell from height to climb. That is why this instrument is often used by firefighters.

Classification according to type

The flat sling is the most popular. It consists of a strip similar to a belt that you usually have one or two hooks, although there are also eye and eye flat slings (with folds like grommets at the ends) and flat inverted eye slings (whose eyes are crooked).

The multi-link sling, the endless sling and the ratchet sling They are other kinds of flat slings. The cylindrical, tubular or round slings, meanwhile, have a different design and are generally more flexible and elastic than flat ones.

Sling Maintenance

To avoid damage to the sling, and therefore minimize the risk of accidents, it is important to analyze your state before and after use. If the rope is frayed or cut, it should not be used.

It is easier to maintain the integrity of the rope if it is washed after use and stored dry (i.e. without humidity).

On the other hand, they should not be knots with the sling or use it when it is turned on itself. Otherwise it is more likely to end up breaking.
