Drag Chains for Automated Sorting and Grading Systems


In today’s automated industries, sorting and grading systems play a crucial role in streamlining the production process. These systems require reliable and efficient components to ensure smooth operation, and one such essential component is the drag chain. In this article, we will explore the various aspects of drag chains and their significance in automated sorting and grading systems.

1. Understanding Drag Chains

Drag chains, also known as cable carriers or energy chains, are flexible protective devices designed to guide and manage cables and hoses in automated machinery. They provide a safe and organized routing system, keeping the cables secure and preventing tangling or damage during repetitive movements. These chains are typically made of high-quality plastic or metal links, allowing for smooth and reliable motion.

2. Importance of Drag Chains in Automated Sorting and Grading Systems

Automated sorting and grading systems involve constant movement and positioning of components, making drag chains an indispensable component. Here are some key reasons why drag chains are vital:

2.1 Cable Protection

Drag chains shield cables and hoses from external factors like abrasion, oils, dirt, and other contaminants. This protection extends the lifespan of the cables, ensuring uninterrupted operations and reducing maintenance costs.

2.2 Cable Management

With their ability to neatly organize cables, drag chains minimize cable entanglement, reducing the risk of malfunctions and downtime. They also make troubleshooting and maintenance easier by providing clear cable routing paths.

2.3 Flexibility and Durability

Drag chains exhibit excellent flexibility and durability, allowing them to withstand the rigors of continuous movement in sorting and grading systems. They are designed to cope with high speeds, accelerations, and decelerations, ensuring reliable performance even in demanding environments.

2.4 Enhanced Safety

By keeping cables and hoses securely contained within the chain, drag chains eliminate the risk of tripping, tangling, or accidental damage. This significantly enhances operator safety, which is crucial in automated manufacturing environments.

3. Types of Drag Chains

There are various types of drag chains available, each with its unique characteristics and suitability for specific applications. Let’s explore a few commonly used types:

3.1 Plastic Drag Chains

Plastic drag chains are lightweight and cost-effective solutions. They offer excellent resistance to chemicals, corrosion, and impact, making them suitable for a wide range of industries.

3.2 Flexible Chains

Flexible chains, as the name suggests, provide exceptional flexibility, allowing them to bend and twist easily. They are ideal for applications that involve intricate and dynamic movements.

3.3 Bushchains

Bushchains are specialized drag chains that offer enhanced wear resistance. They are often used in applications where heavy loads and harsh operating conditions are present.

3.4 Tabletop Chains

Tabletop chains are flat-surfaced chains commonly used in conveyor systems. They are highly durable, with excellent load-bearing capabilities, ensuring smooth and efficient material handling.

3.5 Multiflex Chains

Multiflex chains combine the benefits of plastic and steel components, providing a balance between flexibility and strength. They are suitable for applications that require both flexibility and high load-bearing capacity.
