Expanding Energy Chain Capacity for Machine Tool Modernization

igus is releasing extender crossbar clips designed to increase the internal height of existing energy chains by up to 200 percent. This modular hardware targets mechanical engineers conducting industrial equipment upgrades who must accommodate larger hydraulic, coolant, or extraction hoses without replacing entire cable carrier systems.

Overcoming Capacity Constraints in Industrial Upgrades
Machine tool modernization frequently involves installing more powerful extraction units or upgrading fluid delivery lines. These larger diameter hoses often exceed the dimensional limits of standard cable protection systems. Historically, accommodating these larger elements required the complete replacement of the energy chain, leading to oversized systems and increased component costs. At the AMB trade show in Stuttgart (September 15 to 19), a retrofit solution was presented to modify rather than replace the existing carrier framework.

Modular Architecture and Dimensional Expansion
The extender crossbar clips operate on a tool-free modular principle that alters the carrier's geometry. Technicians manually unclip the existing crossbars from the locking mechanisms of the energy chain and insert the gate-shaped extender clips. Depending on the carrier model, this physical modification yields up to a 200 percent increase in internal clearance. Dieter Reitz, Sales Manager for e-chains at igus, notes that this modular approach makes the E2.1, E4QL, and E4.1L series significantly more adaptable to changing structural parameters. The solution is specifically compatible with the E2.26, E2.38, E2.48, E4Q.64L, and E4.64L series.

Application Across CNC and Laser Cutting Systems
The capacity to alter interior dimensions post-installation directly applies to the retrofitting of CNC milling machines, lathes, laser cutting equipment, and grinding machines. By generating the required vertical clearance for thicker extraction hoses or advanced cooling lines, the clips enable existing energy chains to remain operational. Retaining the original structural components reduces both capital expenditure and material waste during mechanical overhauls.

Additional Context

Cable carriers are standard protective frameworks in industrial automation, with major global suppliers including Tsubaki Kabelschlepp, Murrplastik, and igus. Traditional capacity expansion in these systems generally requires purchasing a new chain with a larger bend radius or wider internal links. The modular crossbar extension approach introduces a distinct mechanical alternative to complete system replacement, yielding efficiency gains in retrofit installation times. While competitors offer varied crossbar designs—such as adjustable aluminum frame stays or custom-milled internal dividers—tool-free snap-on vertical extenders that independently increase carrier height represent a specialized mechanism for post-installation dimensional adjustment.
