Cable carriers, also known as drag chains, energy chains, or cable chains depending on the manufacturer, are guides designed to surround and guide flexible electrical cables and hydraulic or pneumatic hoses connected to moving automated machinery. They reduce wear and stress on cables and hoses, prevent entanglement, and improve operator safety.

Cable carriers (also known as cable tracks and energy chains) are flexible hollow structures composed of links to help guide and protect cables, hoses, and hydraulic lines on equipment and machinery.

Energy chains (also called e-chains, drag chains or cable carriers) are mechanical machine elements. They are used to guide and protect cables, data and signals that have to withstand the most diverse environmental influences. E-chains or drag chain include cables, hoses, interior separation elements, strain relief devices and guide troughs.
