Welding, riveting, soldering: Industrial robots must work dynamically and quickly in production. Therefore, a safe and compact guidance of cables and hoses is required. This is where the three-dimensional triflex energy chains from igus are used. If the e-chains form loops in the work area of the robot, it can damage the cables and hoses as well as lead to machine failure. For this reason, igus has now developed the new low-cost TR.RSEL retraction system. The system guides the energy chain in a line on the robot, ensuring trouble-free and fail-safe operation.
