The distance between supports and hangers determines the span of the cable tray. According to

The distance between supports and hangers determines the span of the cable tray. According to the bridge standard, the thickness of the connecting piece of the long-span cable tray should be the same as that of the main structure of the bridge frame.
The following is a description of the relevant content for your reference.
1. The standard lengths of straight line segments of long-span cable tray are generally 2m, 3m, 4m and 6m.
The standard length of ordinary cable tray is generally 2m.
The length of long-span cable tray is generally more than 2m.
For the cable tray with high load whose span is larger than the standard length or considering the effect of outdoor wind and snow, it is necessary to use enhanced side plates or enhance the height of the bridge, or corrugated cable tray to ensure its safe load.
2. Thickness standard bridge thickness standard includes bridge plate thickness standard and bridge protective layer thickness standard, bridge plate thickness standard includes pallet, cover plate and connecting plate thickness, bridge bridge protective layer thickness standard includes zinc layer thickness and coating thickness and so on.
In the bridge standard, the thickness requirements of spraying process surface coating > = 50um, electrogalvanized surface zinc layer thickness > = 12um, hot-dip galvanized surface zinc layer thickness > = 65um.
Thickness requirement of VCI bimetallic coating > = 60um.
3. The surface protection treatment of the connecting piece cable tray accessories, such as the connecting piece, should be consistent with the protection requirements of the main structure of the bridge frame, and the surface protection treatment of the supporting supports and hangers should be determined according to the specific technical requirements of the project.
The thickness of the connecting piece of the cable tray should be the same as that of the main structure of the cable tray, or one thicker.
