Drag chains, also known as cable carriers or energy chains, come in various types to suit different applications and requirements. The choice of drag chain depends on factors such as load capacity, travel distance, environment, and the specific needs of the machinery. Here are some common types of drag chains:

Open Type Drag Chains:

These chains consist of individual links that are open on both sides, allowing for easy access to cables and hoses. They are suitable for applications where frequent maintenance or changes to the cables are necessary.
Enclosed Type Drag Chains:

Enclosed drag chains have a protective cover over the links, providing better protection for cables and hoses. They are suitable for applications where environmental conditions may be more challenging, such as exposure to debris, dust, or liquids.
Steel Drag Chains:

Steel drag chains are constructed with steel links, making them durable and suitable for heavy-duty applications. They are often used in harsh environments where resistance to abrasion, impact, and chemicals is essential.
Plastic Drag Chains:

Plastic drag chains are made from high-strength, lightweight materials such as nylon or reinforced plastic. They are suitable for applications where weight is a concern, and they provide good resistance to corrosion.
Combination Drag Chains:

These drag chains combine both steel and plastic elements. The outer links may be made of steel for strength, while the interior links are made of plastic to reduce weight and friction.
Low-Noise Drag Chains:

These drag chains are designed to minimize noise during operation. They often feature noise-reducing elements such as special links or interior separators to dampen the sound generated by moving cables.
Miniature Drag Chains:

Miniature drag chains are designed for smaller applications where space is limited. They are often used in applications like robotics or medical equipment.
Accordion Type Drag Chains:

Accordion or bellows-type drag chains are flexible and expandable, allowing for increased length when extended. They are suitable for applications where the travel distance of cables varies.
Specialized Drag Chains:

Some drag chains are designed for specific applications, such as those requiring resistance to extreme temperatures, chemicals, or electromagnetic interference (EMI). These specialized drag chains may have unique materials or features to meet specific challenges.
When selecting a drag chain, it's essential to consider factors such as load capacity, speed, environment, and the type of cables or hoses being protected. The choice will depend on the specific needs of the machinery and the working conditions.
