Large energy chains guide and protect the cables and hoses in the most demanding heavy-duty applications, from indoor cranes and port equipment to construction machinery, machine tools running large cables, and robotics. Available in inner heights from 21 mm to 350 mm, these high-strength plastic chains are engineered for long, unsupported and gliding travels, carrying high fill weights at high speeds while standing up to dirt, debris, shock, vibration, corrosion, and UV. Features such as undercut side links for lateral stability, high push and pull forces, and integrated noise-reducing elements keep operation stable and quiet even under load. Crossbars open along the inner and outer radius for fast filling, and extensive interior separation keeps large cable packages organized and protected against wear. Backed by a four-year guarantee and available from stock, large e-chains deliver a rugged, long-life alternative to festoons and cable reels.
