CHOOSING THE APPROPRIATE CABLE TRAY/LADDER
Next, we select the appropriate cable tray / ladder for the total weight of cables (calculated in Step 5). The load capacity of the cable trays / ladders can be found in the load curves, relative to the span.
All ELVAN cable trays / ladders are tested in-house acc. to EN 61537.
The key factors for the load capacity of any cable tray / ladder are:
- Support spacing
- Side height and
- Material thickness
We strongly recommend not exceeding a support spacing of 1.5 meters if possible.
