3" NEMA VE 1 Loading Depth
4" Side Rail Height
Values are based on simple beam tests per NEMA VE 1 on 36" wide cable tray with rungs spaced on 12" centers. Cable trays will
support without collapse a 200 lb. (90.7 kg) concentrated load over and above published loads. Published load safety factor is 1.5.
To convert 1.5 safety factor to 2.0, multiply the published load by 0.75. To obtain mid-span deflection, multiply a load by the deflection
multiplier. Cable tray must be supported on spans shorter than or equal to the length of the cable tray being installed.
Individual rungs will support without collapse a 200 lb. (90.7 kg) concentrated load applied at the mid-span of the rung, over and above
the NEMA rated cable load with a 1.5 safety factor for highlighted NEMA spans and loads.
