Low-cost igus energy chain for unsupported applications A new addition to the igus energy chain portfolio: the E4Q, a globally proven e- chain for applications with large unsup- ported lengths and high fill weight, now has a new L variant. Where the E4Q is too large, users can now save up to 20% with the new E4Q.64L, while still benefiting from the advantages such as quick and tool-free opening. “Depending on the width, the low-cost version of the energy chain costs be- tween 15% and 20% less than the E4Q.” he says. To reduce costs, the side links are
the first igus energy chain with three stop-dogs per chain link,” says Ziegler. “This ensures an even more regular pow- er flow and a longer service life.” Tests in the igus test laboratory prove that the E4Q.64L has an approximately 30% greater breaking moment than the 14240 series, which is also used for un- supported applications. This results in up to 20% more length with the same fill weight. www.igus.co.za
narrower than those of the E4Q, reduc- ing the weight. The bionic design, which dispenses with any material that has no load-bearing function, was retained. "The stop-dog system was completely rethought, resulting in improved service life than predecessors. The E4Q.64L is
From the seventh robot axis in linear robot applications to machine tools, the igus E4Q-series energy chain has estab- lished itself in recent years in demand- ing applications with large unsupported lengths and high fill weights. There are two reasons for this. One is that the e- chain's wide side links and four stop-dogs per chain link make it very robust. The other is that assembly time is reduced by up to 40%, because the cross- bars can be opened in seconds, without tools and with just two fingers. The problem is that, in applications with medium loads the E4Q is over- sized. “To offer users the advantages of the E4Q in these applications as well, and at a lower price, we developed the E4Q.64L,” says Christian Ziegler, head of e-chain product management at igus.
The new E4Q.64L shines in applications with medium loads, such as machine tools, and features high strength, long service life and low weight.
