Abstract: Cable carriers having laterally stabilized tabs made of plastic. An arc-shaped guide region of one tab engages in a free space behind a retaining nub on the other tab. The retaining nub provides lateral stabilization. According to the invention, the retaining nub is spatially limited to a middle height section of the tab height and limited in dimension in the circumferential direction about the pivot axis. The arc-shaped guide region is thus overlapped solely by a smaller proportion, preferably ?33%, of the arc length or angle width thereof by the retaining nub and remains not overlapped (that is, laterally free) over a predominant proportion, particularly 66%, of the arc length or angle width thereof by the retaining nub. This particularly facilitates the assembly of the chain tabs and their connection to each other.

Abstract: A transverse bar for a chain link of an energy guiding chain for guiding lines. The transverse bar has an elongate main body comprising a first plastic and at both longitudinal ends a connecting region for connection to the side plates. The main body of the transverse bar has two long narrow sides which each have a holding device for separating bars. Provided on the inside of the main body that faces towards the lines is a line-protecting layer for handling the lines gently and comprising a second plastic which is different from the plastic of the main body and is selected to reduce abrasion upon relative movement between a line and the transverse bar. In that case the line-protecting layer extends from one narrow side to the other and at least predominantly covers over the inside of the main body but leaves uncovered the respective holding device at the one narrow side and at the other narrow side.

Abstract: The invention relates to cable carriers having laterally stabilized tabs made of plastic. An arc-shaped guide region (120A, 120B) of one tab (102) engages in a free space (123) behind a retaining nub (121A, 121B) on the other tab. The retaining nub (121A, 121B) provides lateral stabilization. According to the invention, the retaining nub (121A, 121B) is spatially limited to a middle height section (hl) of the tab height and limited in dimension in the circumferential direction about the pivot axis (A). The arc-shaped guide region (120A, 120B) is thus overlapped solely by a smaller proportion, preferably ?33%, of the arc length or angle width (a) thereof by the retaining nub (121A, 121B) and remains not overlapped (that is, laterally free) over a predominant proportion, particularly 66%, of the arc length or angle width (ßa) thereof by the retaining nub (121A, 121B). This particularly facilitates the assembly of the chain tabs and their connection to each other.

Abstract: A tension relief for a cable carrier. A multi-part holding frame comprising bars which are connected by side parts holds block-like spacers, between which a plurality of lines, such as cables, hoses or the like, are laid. In order to exert a clamping force by the holding frame on the spacers for the purpose of strain relief, a quickly closable device is provided. A quick release clamp can be provided, which in the closed position clamps the side parts and/or the bars to one another. According to the invention, the two side parts are mounted pivotably on the lower strip and are fastened releasably to the first bar, for example by screws or the quick release clamp. Each side part can thus be pivoted from the closed position into an open position and vice versa in order to release and clamp the lines respectively.

Abstract: 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.

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.

Abstract: An energy guiding chain and side part therefore are proposed. In energy guiding chains, the pivotability of connected chain links against each other is typically limited by cooperating abutments with abutment surfaces arranged on the side parts. The invention concerns elastically deformable damping elements which dampen the abutting motion of the areas between the abutments and the abutment surfaces. In accordance with the invention, at least some abutments have a damping bow which is convexly curved in the direction of the respective other abutment surface and behind which a free space is provided, both ends of the damping bow being firmly connected to the respective abutment in the manner of an arched bridge. Furthermore, the damping bow is connected in one piece to the inner wall of the respective side part facing the inner guide channel.

Abstract: A monitoring system for the operation of an energy chain. This has a movable strand, a stationary strand and a deflection bend therebetween. The system comprises at least one sensor which generates at least one output dependent on the condition of the energy chain, and an evaluation unit which evaluates the at least one output of the sensor in order to monitor whether a fault condition occurs during operation of the energy chain. The sensor has a non-contact working principle and is arranged so that the sensor interacts from a distance with at least a subregion of the deflection bend and/or a subregion of the movable strand. The sensor thus generates an output which is dependent on the position and/or speed of the energy chain.
