Energy chain E4Q.L

Large inner height, low weight - The best mix of stability and low weight. Highly dynamic, save up to 40 % assembly time ► Can now be opened by hand

Based on the successful E4Q, the first sizes of an L version with an inner height of 64 / 58 mm are now available. Easy to open by hand with quick opening bar. crossbar of the E4Q.58/82 are used = complete width range directly available.

The bionic design, which allows increased stability and service life while reducing the weight at the same time. And the quick-opening bars, which enable simple and intuitive opening/closing of the chain. Another advantage of the growing E4Q modular system: no new crossbars need to be made for the new E4Q.L series, as those of the E4Q.58 have been adopted. This means that the complete width programme from 100 to 500 mm with a total of 29 widths is directly available

E4Q is successful - so why the L version?

Many applications do not need the E4Q's thickness at all. Energy chains with a smaller wall thickness are sufficient to guide the cable packages. This is especially true of unsupported energy supply systems with low or medium loads, such as those in machine tools, woodworking equipment, and car washes. igus has developed the L version to offer users the advantages of the E4Q in these applications as well, and at an attractive price. Depending on the width, the E4Q.L costs about 15-20% less than the E4Q.58, but is about 40% stronger than the predecessor models (the "E4 Light" and "E4.1 LEAN"). "Thanks to the outstanding strength of the E4QL, we can serve completely new applications more cost-effectively than ever before while offering the proven E4Q advantages," says Christian Ziegler, Head of e-chain® Product Management.

New stop-dog system

"We have completely rethought the stop-dog system. The development goals were more stability and service life than the predecessors with two stop-dogs, while still being able to realise a reverse bend radius," says development engineer Stefan Strack. Reverse bend radius means that the energy chain can bend in two directions. The result of this development process is the first igus® energy chain with three stop-dogs. The proven inner/outer link principle has been expanded to include a clever, innovative reverse bend radius option: the inner link continues to determine the bend radius of the chain via the size of the stop pocket. For the first time, the outer link is used to realise the reverse bend radius. By reducing the size of the stop-dog, the chain can be "bent over the back" at predefined angles.

Tech up

More room for cables thanks to the greater inner height (64mm) and reduced weight
Proven E4Q design and approx. 10% stronger than the previous 14040 series

Cost down

Reverse Bend Radius applications possible as standard without conversion/retrofitting
Depending on the width, around 10-15% more cost-effective than the E4Q.58 thanks to slimmer side links
40% stronger than the predecessor models (E4 Light and E4.1 LEAN)

Proof

Tested and developed in the igus laboratory

Sustainability

Reduced use of materials thanks to L design (about 15% lighter than E4Q.58 with the same width)

Easy e-chain® extension

extension link for the E4Q.L
With the extension link, an existing e-chain® configuration can be easily extended to run a large number of cables or particularly heavy cables in a chain.

Simply guide additional cables and/or realise a higher filling weight
Using the extension link saves an additional e-chain®
Further optimisation based on the tried-and-tested E4 extension link, which is used successfully in numerous applications
