Load-bearing capacity of 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. They are not only suitable for the overhead laying of indoor and outdoor cables in industrial and mining enterprises such as petrochemical. Safe working loads are represented graphically as shown and are based on the cable tray being continuous over four spans or more. Deflection has been limited to SPAN/200 generally, based on the end span condition as the worst case. However, on. UNITRAY LADDER TRAY is a structure consisting of two longitudinal side members connected by individual transverse members (rungs). Both processes have their inherent advantages and. For heavy power cables or long spans, ladder trays typically perform best. For mixed small cables, perforated works well. Width is set by total cable area plus spare factor; depth helps maintain side containment and segregation. Live Load (Q): Temporary loads such as maintenance personnel, tools, and other equipment placed on the tray.
