Breaking Down the Differences Between Lifting and Pulling Chains

Have you ever wondered about the different types of chains and their uses? Chains are versatile tools that have been used for centuries in various industries. And while they may all look similar, not all chains are created equal.

In fact, there are two main categories of chains: lifting and pulling. These two types serve specific purposes and understanding the differences between them is a must for anyone looking to use a chain for their work. So if you're curious about how these seemingly similar tools differ, keep reading for all the information!

Availability and Cost

Lifting chains are often made from high-grade, heat-treated steel to ensure maximum strength and durability. There are many certified lifting solutions for industrial operations — Grade 80, Grade 100, and even Grade 120 — that may come at a higher price tag. These chains have to meet stringent safety standards and are subjected to regular inspections to maintain their certification.

Pulling chains, which are used to drag or tow loads horizontally, are often made from less expensive materials since they do not have to support the entire weight of a load vertically. Consequently, pulling chains are more widely available and are a cost-effective option for many operations, making them a preferred choice for businesses looking to balance efficiency with budget constraints.

Purpose and Use

As the name suggests, lifting chains are primarily used for hoisting or lifting heavy loads. They are designed to withstand high tension and have specific engineering properties that enable them to bear weight vertically without breaking.

On the other hand, pulling chains are more suitable for dragging or towing loads horizontally. They are designed to withstand tension in a straight line and may not be suitable for lifting purposes. Still, they can be incredibly useful in pulling or securing heavy equipment, vehicles, and other items that require horizontal movement.

Strength and Durability

Because they are made from materials that can resist wear and tear, lifting chains are built to withstand extreme loads and harsh environments. As mentioned earlier, these chains are also subject to regular inspections, ensuring that they maintain their strength and durability. Lifting chains often have a higher weight capacity than pulling chains, a reliable choice for handling heavy loads in industrial settings.

Pulling chains may not be as strong or durable as lifting chains since they don't need to support the full weight of a load vertically. However, they can withstand a significant amount of tension and are suitable for dragging or towing lighter loads.

Link Design

For lifting chains, the links are mostly shorter and thicker, providing more surface area for distributing weight evenly. This design aims to prevent any weak points or stress concentrations that could cause the chain to fail under pressure.

Compared to lifting chains, pulling chains have longer and thinner links, allowing the chain to flex more easily and accommodate various angles. It's a type of design that allows the chain to wrap around objects and maneuver easily during pulling operations.

Safety Standards

Most importantly, lifting chains are subject to strict safety standards and regulations. They are often inspected and maintained by certified professionals to ensure they can handle the weight and stress of lifting heavy loads safely.

Although pulling chains do not have the same rigorous safety standards as lifting chains, it's still crucial to use them safely and correctly. Know the appropriate weight capacity of a pulling chain and never exceed it to avoid accidents or equipment damage.

Attachments and Accessories

Another key difference between lifting and pulling chains is the variety of attachments and accessories that can be used with them. Lifting chains often come with specialized hooks, clevises, and other fittings designed for lifting purposes. These attachments are specifically engineered to work with lifting chains and ensure proper weight distribution and secure connections.

Pulling chains also have a wide range of attachments available, but they are typically more basic and versatile. These may include clevis hooks, grab hooks, and eye slip hooks that allow for a variety of pulling scenarios. No matter the attachment, make sure it is suitable for the weight capacity and intended use of the pulling chain.

Maintenance and Care

The maintenance and care requirements for lifting and pulling chains also differ due to their unique applications and material composition. Lifting chains require meticulous maintenance to ensure they remain in optimal condition, including regular inspections for signs of wear, damage, or corrosion, and lubrication to maintain their flexibility and prevent rust. The high stakes associated with lifting heavy loads vertically mean that any compromise in a lifting chain's integrity can result in catastrophic failures, emphasizing the importance of stringent maintenance routines.

While pulling chains do require basic care to extend their lifespan, the maintenance regimen is generally less rigorous than for lifting chains. Since pulling chains are primarily used for horizontal movements and are not subject to the same level of critical load-bearing stress, the potential for catastrophic failure due to compromise is much lower.

Lifting and pulling chains are essential tools in various industries, each designed with specific features that cater to their primary functions of vertical lifting and horizontal pulling, respectively. Understanding the distinctions between the two, from their material composition and design to their safety standards and maintenance requirements, is crucial for selecting the right chain for the job. By recognizing these differences and adhering to proper usage and care, operators can ensure the safety and efficiency of their operations while maximizing the lifespan of their chains.
