Gliding e-chain cable carriers are typically used for travel lengths between 33 and 164 feet. However, more demanding requirements are currently being placed on these e-chain systems. The required dynamics of the systems are intensifying, and the loads that the chains must handle are increasing. This can cause gliding systems to reach their physical limits. For example, if the cycle rates of machines increase, energy chains must move faster as a result. Therefore, igus has expanded the standard modular system of the E4.1 e-chain series by adding new roller links.
