Zigzag e-chain modules: providing energy for vertical applications

Shery George | 29 September 2021


For applications that require vertical cable management, especially those with space constraints, the zigzag energy e-chain modules from igus® have proven to be particularly successful.  Standard zigzag energy chain modules are available from igus®, offering a space-saving and cost-effective solution for applications requiring vertically moving cable management.  Ideal for stage technology, cranes, telescopic antennae etc, this innovative solution was previously only available as a custom order.  Now new, standardised modular designs enable faster delivery and lower cost.  In modern stage technology, a variety of cables – including power, audio and data – must be managed to move and operate lighting trusses or mobile stage elements, usually vertically.

To ensure reliable supply of data and energy, it is therefore also necessary to guide and protect the cabling vertically too.  This can often be challenging in theatre environments: solutions must be visually neat, tidy and unobtrusive, operating with little noise and often in restricted spaces.  Other applications requiring vertically suspended cable management include hydraulic lifting platforms, often used where temporary, flexible access is required, such as storage, maintenance or construction.

The zigzag module from igus® provides a folding energy chain, with all the cables guided safely and neatly stowed away in a standardised box when the platform is in its lowered position.  When the platform is raised, the e-chain® unfolds and follows the movement – up to 30 metres in height. The intelligent design of the zigzag movement means virtually silent vertical operation, unlike traditional rope retraction systems.

The system is also able to carry very high cable and hose loads. The galvanised steel box can be unobtrusively integrated into stage elements or fastened to movable lighting rigs, and is also available in any colour, including low-reflection black.  For customers with demanding vertical cable management requirements, this innovative zigzag solution is ideal.  Previously, customers would specify it individually or in small batches as a custom order. The standard box also provides an ideal means of transport for the energy chain pre-fitted with cables.

This means it can be delivered as a complete system and quickly fitted as a ready-to-install plug & play system with e-chain® chainflex® cables and connectors in the same system. If the standard option doesn’t suit your application, igus® offers a full complete custom system. This starts from a customer requirement and finishes with a completely customised system, engineered and supplied by igus®. To ensure that the system reaches the customer intact, wooden transport crates can be supplied for added protection when delivering from factory to site.
