Laying of cable trays
Thread Content
Currently, the cables are located above the fire escape, with a span of 10.7 meters. It is proposed to install I-beam supports at each end, connected using 100-channel steel, with the cables placed inside these channels. Is this feasible? Could a fellow member help check whether the channel steel will bend under a span of 10 meters?
It will bend. It would be better if it were viewed upright.
Excuse me, how do I align it properly? {:2_30:}
It’s placed like this (in the work). ---------------------
10 meters of span is not a big problem; what is your height?
The cables are placed in trunking or cable trays, mounted on I-beams
4.2 meters in height – needs to pass through a fire truck
It involves using channel steel to hold some cables; how should they be placed?
Using channel steel is also an option; the cables can be placed inside it. Weld it firmly at both ends, and add a support at the right angle. Make a few small holes in the channel steel for drainage.
Thank you, :victory::handshake
It’s possible, but it’s not appropriate to place cables directly on the cable tray base. If you have fewer cables, it is recommended that you use a galvanized pipe on the base.
