Energy Chains for all Industries and Applications
For around 50 years, we have specialised in the production of custom plastic, hybrid, and steel drag chains for a variety of applications. From the design to the installation of a finished product, you will receive perfectly tailored solutions that combine cables, chains, and accessories. Our portfolio includes self-supported chains for short travel distances, gliding products, and rolling designs for longer distances and maximal additional loads. Special gliding blocks reduce wear, and trough systems reliably guide chains.
Our mission:
To set connections in motion. Our drag chains stand for flexibility in application, smooth operation, perfect protection for cables, and for maximum efficiency in all applications.

Expertise in Energy Chains
Drag chains, also known as energy chains or cable chains, are flexible duct systems found in many different applications and are utilised in the transmission of energy and signals from a fixed source to a moving destination.
They protect cables and wires from abrasion, wear, and other damages caused by movement, vibrations, or environmental factors. They allow cables and wires to be specifically organised to improve the operation of machines and plants. Drag chains are often found in industrial applications such as in mechanical engineering, automation technology, robotics, and material handling technology.
In our product overview, you can find a large selection of drag chains in different sizes, materials, and designs to meet the requirements of your application.
Plastic Drag Chains
Our plastic drag chains are optimal for light and mid-weight loads and are often utilised in automation technology, robotics, and mechanical engineering. Their most prominent features are their light weight, durability, resistance to corrosion, and high flexibility, which make them ideal for applications with dynamic movements. In comparison to their steel counterparts, plastic drag chains are quieter, more affordable, and are easier to install.
Kolibri Plastic Drag Chains
The Kolibri plastic drag chain is a very affordable cable duct for light industries. The integrated plastic connector replaces specialised connection attachments.
This drag chain is used in robotics, handling technology, conveyor technology, paper, and textile machines, and many more.

PKK Plastic Combo Chain
The PKK combines all of the advantages of plastic cable ducting in a singular system. The PKK combo chain can be opened and closed, as well as have its length, width, and height adjusted, without the need for a specialised tool.
These chains are utilised in a variety of applications including robotics, handling technology, intralogistics, tooling and textile machines, and many more.

PFR Plastic Tube
The PFR plastic tube is suited for short travel distances. Its sleek, closed design fulfils both form and function, while still being easy to adjust lengthwise.
Applications: Tooling and welding machines, sheet metal processing, and many more.

Steel Drag Chains
We also manufacture high-quality cable drag chains made of steel and stainless steel designed for the most extreme conditions, offering uncompromising reliability where it matters. Our steel drag chains can be found performing to the highest degree in the tunnelling and mining industries, as our drag chains are the clear choice when it comes to tackling such extreme challenges.
SLE Steel Link Drag Chain
The SLE steel link drag chain is available in steel, stainless steel, and hardened steel designs, and it can be delivered assembled with hole crossbars (SLE and SLA), foam crossbars (SLS), plastic intermediate crossbars (SLP), and tube crossbars (SLR).
Industrial applications include tooling machines, the food and beverage industry (stainless steel), mills, specialised machines, mining, offshore industries , and many more. Our experts look forward to advising you on pre-assembled, complete drag chains.

GKA Large Steel Chain
The large GKA steel chain is used in applications calling for a large number of cables and hoses with large outer diameters, as well as in in applications with self-supported travel distances up to 18 m. This drag chain is also available in V4A stainless steel and in customised designs.
This chain is used in heavy machinery, steel production, mills, in large-scale and offshore plants, and many more.

SFK Steel Tube
The closed steel casing of the SFK steel tube provides cables and hoses with good protection against hot shavings, welding beads, and sparks. The SFK steel tube is a proven solution for many specialty tooling machine applications with short travel distances and limited movement cycles.

Hybrid Drag Chains
Hybrid drag chains combine the benefits of plastic and metal drag chains and are an ideal solution for applications that require both flexibility and high stability. They are characterised by their low weight, high resistance against abrasion and corrosion, and their superior resistance to chemicals. These characteristics make hybrid drag chains especially suited for use in demanding environments such as in automation technology, mechanical engineering, and in robotics applications.
PLE Hybrid Drag Chain (Plastic Chain with Aluminium Crossbars)
The PLE plastic drag chain with aluminium crossbars is a more cost-effective and lighter solution than steel drag chains. When installed in a trough, this chain slides over itself in applications with travel distances up to 100 m.
The PLE hybrid drag chain can be found in tooling machines, handling technology, conveyors, hoisters, and many more.

Alongside our expansive portfolio of proven, high-quality standard solutions, HELUKABEL offers pre-assembled drag chains that are designed to perfectly fit the individual requirements of your application.
