In a comparison test in the industry's largest test laboratory in Cologne, igus® compared its plastic R4.38L energy chain with a competitor's product. In a fracture test, the two chains were evaluated in respect of their appearance, their behaviour when subjected to tensile forces and their load capacity; their ease of installation was also assessed.
| igus® R4.38L | Competitor´s chain | ||
|---|---|---|---|
| 1.5 m unsupported length with 4 kg/m additional weight |
