Deflection value of steel cable trays
The safe working load (SWL) is the evenly distributed load at which the transverse deflection of the cable tray is less than 1/100th of the span between supports in the longitudinal direction, as. When a cable tray system is installed in a prominent location, a maximum simple beam deflection of 1/200 of support span can be used as a guideline to minimize visual deflection. Economic consideration must be considered when addressing cable deflection criteria. Deflection has been limited to SPAN/200 generally, based on the end span condition as the worst case.
