Support issues for large-span outdoor cable trays
Thread Content
For the outdoor area, a 6-meter-long tray is being used; the process pipes are supported by pillars every 6 meters. The tray is of the trough type and 200 meters wide. It is planned to use the pillars for supporting the process pipes. Is a spacing of 6 meters too large? If so, how should it be installed?
A spacing of six meters is usually too large for a 200-mm-wide trough-type cable tray, as it can easily cause the tray to deform or sag. It is recommended to reduce the spacing between supports, or add additional tray supports on the process pillars. If necessary, a bridge rack hanger or support can be added in the middle to ensure the stability and load-bearing capacity of the bridge rack. .
To take advantage of the pillar mounting method, a support arm can be installed every three meters along the cable tray.
Spacing evaluation: A spacing of 6 meters may be acceptable for certain cable tray applications, but it depends on the weight, quantity, and type of cables in the tray, as well as environmental conditions such as wind load and temperature changes. If the cables on the cable tray are heavy or numerous, or if the environmental conditions are harsh (such as strong winds or high temperatures), a spacing of 6 meters may be too large; in such cases, it is necessary to consider adding more support points or using additional support measures. Installation recommendation: If the 6-meter spacing is too large, additional tray supports can be added between the two process pillars. These brackets can use the same materials and installation methods as those for process pillars, ensuring the stability and safety of the cable tray. If the structure and location of the process pipeline supports permit it, the cable tray brackets can be directly welded or fixed to the process supports. This ensures the stability and reliability of the cable tray. If the structure or location of the process pillar does not allow for direct mounting of the cable tray supports, structures such as suspension rods or cantilever supports can be used to hold the cable trays in place. These supports need to be designed and installed according to specific conditions to ensure their stability and safety. During installation, attention must be paid to the levelness and verticality of the cable tray to ensure that the cables can be laid and secured smoothly within it. At the same time, attention must also be paid to the distance and relative position between the cable trays and the process pipelines, in order to avoid mutual interference or damage.
It will soften, especially since it tends to deform when cables are installed there frequently; for a width of 200, it’s recommended to use sections two meters long
