The safe working load obtained guarantees: • A maximum longitudinal deflection of 1/100th of the span (example: 20 mm deflection for a distance between supports of 2000 mm) • A maximum horizontal

Under the current CSA standard clauses 4.3 and 6.1.3, it is now possible to vary the maximum design load for tray as a function of its support span. This allows for heavier tray loading if the support span

The support span is the distance of cable tray between supports. Your cable tray length must always be longer than or equal to the support span you have selected.

Typically, cable trays can span anywhere from 6 to 24 feet without additional support. Several factors influence the maximum span length of a cable tray: 1. Cable Weight. Heavier cables

Commonly called the Load Class, this defines the load-carrying capability of the tray for a specific support span distance. The design and cost of the cable tray is greatly affected by this designation.

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.
