The triflex TRCF energy chain from igus is designed specifically for multi-axis systems. This three-dimensional chain consists of a completely enclosed system. One feature of this robot chain is that it can be quickly opened and filled at the same time, with the flip-open mechanism enabling chainlinks to be opened quickly and easily with a screw driver. This approach allows even large filling diameters to be inserted in record time, therefore triflex TRCF is suited for applications with dirt and chip exposure. The energy chain is now available as a new version with a nominal diameter of 85 millimetres and - as is customary for 3D robot chains from igus - with defined minimum bending radii and torsion stop dogs. This guides and protects hoses and cables reliably in the interior. A rugged stop dog system also ensures high strength. The device can be shortened and extended as needed. Accessories, such as mounting brackets and protectors are also available.
