Load-bearing capacity of corrugated long-span cable trays
Load rating is independent of width. Even though a 900 mm wide tray has six (6) times the volume of a 150 mm wide tray, it cannot carry any more cable weight. When piling cable in tray, the required air separation between cables can be maintained by spacing. Long-span cable trays have a larger support span than ordinary cable trays, with a more sophisticated structural design and greater load-bearing capacity. Follow these steps to generate your accurate Bill of Materials (BOM) and engineering report: Step 1: Define System Specifications: Select your cable tray type. Ladder cable tray is available in widths of 6, 9, 12, 18, 24, 30, 36, 42 and 48 inches with rung spacings of 6, 9, 12 or 18 inches. Specifiers should be aware that some cable tray. Result: The cables alone add 2850 lbs to this 100-foot tray section. Don't forget the weight of any lids or dividers. Our product is both CSA and UL certified, and utilizes the latest innovations in manufacturing techniques. Unitray is proud to be 100% Canadian owned and the following catalogue.
