What Are the Significant Differences Between Slings and Wire Rope?

Are you still unsure whether to choose slings or wire rope for your lifting needs?

Which tool is more suitable for your needs?

Don’t worry—this article will explain the key differences between slings and wire rope.

We’ll cover their functions, capacities, and their real-life applications in the field.

So, let’s dive into the full explanation below!

Understanding Slings and Wire Rope

First, do you know what slings and wire rope are?

Both are lifting tools essential for moving and transporting heavy loads.

They are both incredibly strong, designed to lift tons of weight and endure high-stress levels.

However, there are significant differences between slings and wire rope usage.

Each has distinct characteristics, leading to different functions as well.

Slings

1. Definition

Let’s start by defining what a sling is.

A sling is a textile-based lifting tool made from strong synthetic fibers, such as advanced nylon and polyester, with high tensile strength.

These synthetic fibers are woven into a strong braid, with sizes adjusted according to their lifting capacity.

Slings come in several types, such as webbing, round, and endless slings.

2. Function

The primary function of a sling is to lift heavy loads.

However, due to its lightweight nature, ability to conform to the shape of the load, and ease of use, slings offer flexibility in lifting.

Slings can be used to lift and move objects to different locations, and due to their flexibility, they are also reliable for securely binding items.

3. Size and Capacity

Slings are available in various sizes depending on their lifting capacity.

The higher the capacity, the wider the sling’s surface, ensuring that the load is evenly distributed throughout.

Slings such as webbing and round slings have a lifting capacity ranging from 1 ton to 10 tons or more.

Thanks to their lightweight and flexible characteristics, slings are popular in various industries.

For example, in the logistics industry, slings transport finished goods while ensuring that the items are not damaged due to the non-abrasive surface of the sling.

In the construction industry, slings are commonly used to lift materials and heavy equipment, regardless of the extreme field conditions.

4. Advantages and Disadvantages of Slings

Slings are lightweight and flexible, making them easy to use for lifting various loads, whether regular or irregular shapes.

Whether they are pallets, packages of finished goods, or piles of irregular construction debris, slings are capable of handling and lifting them everywhere.

Despite being made from textile materials, slings are known for their durability.

Slings are suitable for use in various work environments, including extreme conditions.

This advantage makes slings superior to wire rope because they are not prone to corrosion like wire ropes, which are made of steel.

However, without proper storage, slings may not last as long. Since they are made of synthetic fibers, slings should be kept away from sharp objects, as they may cause tears or holes that could reduce the sling’s lifting capacity.

Wire Rope

1. Definition

Wire rope is a steel cable that is braided using specialized machinery.

Structurally, several steel wires are braided into a strand and then wrapped around a steel core, forming a wire rope.

Despite being made of steel, wire rope is flexible because some wire sections can move while lifting loads.

There are several types of wire rope, including:

• Single-leg Wire Rope Sling: A wire rope consisting of a single steel cable designed for single-point lifting.

• Multi-leg Wire Rope Sling: A wire rope with two or more steel cables connected to a central ring, used for lifting with multiple attachment points.

• Grommet Wire Rope Sling: A wire rope made from a single length of wire twisted into a continuous loop, ideal for lifting heavy and large loads.

• Braided Wire Rope Sling: A wire rope made by braiding several steel cables used for lifting loads with uneven weight distribution.

2. Function

Wire rope is generally used for transporting heavy loads from one location to another.

It is commonly used with cranes or hoists and pulleys.

Wire rope is widely recognized as a robust lifting tool in several industries.

For instance, in the mining industry, wire rope is used to lift mined materials and heavy equipment on site.

Wire rope is also highly reliable in the oil and gas industry.

Wire rope is frequently used in drilling operations and transporting materials in this industry, as it is strong enough to withstand extreme and rugged conditions.

Wire rope is also used in various other sectors outside these industries.

In the tourism industry, for example, wire rope is often used for amusement rides like gondolas, enabling transportation at specific heights.

3. Size and Capacity

Wire rope varies in material, size, and structure.

The wire rope structure forms a helix pattern around the steel core.

However, in some variations, the pattern and mechanism differ to offer more excellent durability.

For example, the 6 x 37 IWRC wire rope is one of the most popular sizes.

This wire rope has a structure with six strands, each consisting of 37 steel wires, surrounding a central steel core (Independent Wire Rope Core).

4. Advantages and Disadvantages of Wire Rope

Due to its metal composition, wire rope is superior in terms of durability.

This tool is ideal for lifting hefty loads.

You don’t need to worry about rough environments or abrasive surfaces, as metal withstands scratches better than synthetic fibers.

However, as expected from a steel material, wire rope tends to be heavier.

Wire rope is more challenging to use than sling belts, which are lighter and more flexible.

Wire rope also requires lubrication before use and regular maintenance.

So, which should you choose: Slings or Wire Rope?

Only you can decide which option best suits your lifting needs.

In some cases, you can choose based on the type of item being lifted, its weight, and the lifting method.

Wire rope might be the solution if you need a lifting tool that can withstand rough and harsh environments.

However, slings are the best choice if you prioritize flexibility, strength, and versatility for various field conditions.
