Today, it is not only electrical and pneumatic cables that are routed on production robots but increasingly also bolts, rivets and nails. Since tight bending radii of the energy chain can lead to complications with these supplies, the new triflex® RSE relies on a very simple and linear retraction without arches and spring rods or guide rollers. In the triflex® RSE, the e-chain® is guided via a linear rail and held in tension with elastic cables. Different cables are used, depending on the required retraction force varying according to the size of the system.
