Energy chain expert igus has completely redesigned many features of its "quiet chain", the fast, quiet, low-vibration "E6" series. The significant weight saving of up to 37 percent (compared to the existing "E6.29") makes greater dynamics and less drive force possible. It is also 2 dB (A) quieter compared with the "E6.29". In addition, the new energy chain is much more modular, it can be extended and shortened as required by simple clipping and can be assembled and taken apart again quickly. The opening cross-bars can now be swung open to both sides by 115 degrees on both the inner and outer radius and no longer have to be removed completely, although this is still possible if required.
