Drag Chains for Robotics


In the field of robotics, drag chains play a crucial role in ensuring the smooth and efficient movement of cables and hoses. These chains, also known as cable carriers or energy chains, provide a protective housing for the cables and hoses, preventing them from getting tangled or damaged during robotic operations. In this article, we will explore the various aspects of drag chains for robotics and their significance in industrial applications.

1. What are Drag Chains?

Drag chains are mechanical systems consisting of interconnected links that form a flexible chain-like structure. They are typically made of high-quality plastic or metal materials and can withstand harsh operating conditions, including extreme temperatures and exposure to chemicals. The primary purpose of drag chains is to guide and protect cables and hoses, allowing them to move freely while maintaining optimal performance.

Drag Chain Application

2. Applications of Drag Chains

Drag chains find extensive usage in various robotic applications across industries. Some common applications include:

2.1 Robotic Welding Systems

In robotic welding systems, drag chains ensure that the cables supplying power and control signals to the welding robot remain organized and protected. They prevent cable damage caused by excessive bending or accidental contact with welding sparks.

2.2 Automated Material Handling

For robots involved in material handling tasks, drag chains provide a reliable solution to manage and support the cables responsible for power, communication, and sensory functions. They ensure uninterrupted operation and minimize the risk of cable failure.

2.3 CNC Machining Centers

Drag chains are essential components in CNC machining centers as they protect the cables for spindle control, tool changer, and other critical functions. They enable the smooth and precise movement of cables, enhancing the overall performance and longevity of the machine.

2.4 Robotic Assembly Lines

In robotic assembly lines, drag chains facilitate the movement of cables and hoses required for operating robotic arms and grippers. They eliminate cable entanglement and ensure the efficient functioning of the assembly process.

3. Advantages of Using Drag Chains

When compared to traditional cable management methods, drag chains offer several advantages:

3.1 Cable Protection

Drag chains provide a reliable and durable housing for cables and hoses, protecting them from abrasion, mechanical stress, and environmental factors. This ensures the longevity and optimal performance of the cables, reducing the need for frequent replacements.

3.2 Enhanced Safety

By securing and organizing cables, drag chains minimize the risk of accidents caused by loose or exposed cables. They also prevent cable damage that can lead to electrical hazards or production downtime.

3.3 Improved Efficiency

Drag chains enable the smooth and unrestricted movement of cables, allowing robots to operate at higher speeds without compromising performance. This results in enhanced productivity and reduced cycle times.

3.4 Easy Installation and Maintenance

With their modular design, drag chains can be easily assembled and installed on robotic systems. They also simplify cable routing and maintenance, making it convenient to replace or add cables as needed.
