A dynamic line guiding system for high speeds and/or long displacement paths, with an energy chain arranged as lying on the side, which chain, in the configuration of a first strand, a second strand, as well as a deflection curve, is displaceable back and forth. The energy chain is guided in a guide trough with two laterally-opposite side walls and a trough floor therebetween, wherein each strand is respectively displaceable with a lateral surface on a respective bearing surface on the trough floor, and is held, relative to the outside, by means of one of the two side walls. It is provided that the trough floor comprises at least one bearing surface with a step or a ramp, which counteracts a deviation of the first strand out of its intended target location on the respective bearing surface.

At least one first section of a cable guide for receiving energy or communication cables in a receiving area can be arranged in the form of a first and second strand (3, 4), which are connected together by a deflecting region (2) extending about a deflecting arc, wherein the cable guide can be moved about the deflecting arc of the deflecting region (2). The aim of the invention is to allow a movement of the cable guide about the deflecting arc in the most frictionless manner possible while keeping the deflecting region stable. This is achieved in that a stabilization element (5) is provided which is substantially adapted to the deflecting arc and is arranged in a deflecting region (2) guide area that extends along the first section of the cable guide and passes through said section at least in one region and which supports the deflecting region (2) in the guide area in a floating manner when the cable guide is being moved about the deflecting arc without emerging from the guide area.

A system for monitoring the state of a cable, which is guided in an energy chain between a base and a movable driver element. The movable energy chain forms a movable run at a driver element, a resting run at a base and, between the two runs, a deflecting bend. A monitoring device having at least one indicating element at the energy chain evaluates an indicating-element signal and monitors whether an error state occurs. The indicating element has two electrical indicating conductors guided by the energy chain, which indicating conductors extend along the movable run, and the monitoring device comprises a measuring circuit for resistance measurement or conductance measurement. One end point of each indicating conductor is connected to the measuring circuit and the other end points of the indicating conductors are short circuited such that the indicating conductors form a measurement loop.
