Cable carriers guide and protect electrical cables, as well as hydraulic or pneumatic hoses. They limit the minimum bend radius and therefore bending stresses, while often also constraining bending to a single plane. They shield and protect cables from wear, prevent entrapment in moving machinery and avoid entanglement. To do this effectively, it is essential that the cable carrier is properly secured to machinery. The method of securing will depend on the type of cable carrier being used. As a minimum, all cable carriers should be securely fastened at each end, using an end connector, mounting surface or junction box. Depending on the type, some additional guiding or securing may also be necessary.
The drag chain style of cable carriers are the most common type. They limit bending to a single plane and are typically used for linear motion applications. This type of carrier usually has a special link at each end with a flat mounting surface containing holes for fasteners. This may be bolted directly to a flat surface, or often to an angled bracket allowing it to be secured to a surface which is perpendicular to the cable run. These cable carriers may be supplied in standard lengths, with end connectors fitted at each end, or be modular in construction. Modular cable carriers are made up of individual chain links which typically snap together using a push-fit connection. When constructing these modular cable carriers, end connectors must be specified and installed.
Longer drag chains, typically over 5 m in length, will operate more reliably if they run in a guide trough. This channel section provides a low friction surface on which the cable guide can run without snagging. Guide troughs must also be securely fastened to the machine or floor. They typically have feet installed at regular intervals for this purpose.
多柔性电缆载体允许在任何方向上弯曲，并且通常用于多轴机器人。这种类型的电缆载体仍然需要在每个端处固定，而且通常需要在其中的多个点处固定。多柔性电缆载体通常在接线盒处的每个端终止。连杆在接线盒处固定在接线盒和中间点，使用夹具的长度。这些夹在电缆载体的圆周周围并提供脚以将夹紧固定到具有螺栓的表面。
