What should we pay attention to when installing tray cable bridge

 

1. For the large load of the cable bridge, the gap between the support points should be less than the span of the support points of the permitted load.

 

 

2, the installation and use of the bridge should be based on national standards and specifications. The bridge shall not be used in the process of installation, such as when the construction site situation is necessary, there must be a security device to take people, this point is very important for the actual operator who is not qualified or non-professional.

 

 

3. The column and bracket bracket of the bridge frame can be welded and fixed with the basic embedded parts, and can also be fixed with expansion bolts. For the welding site of the construction site, anti-corrosion processing must be strengthened, and anti-corrosion paint is generally applied by the user on the construction site.

4. The horizontal laying of the cable bridge is that the gap between the connection point of the bridge and the support point should be within 1/4 of the span. For the large-span bridge to be connected to the support frame, the support point must be added independently in the place with bending energy or tee, and a fixed point is set for the bracket arm in the vertical direction every 1.5m.

 

 

5. The cables in the bridge frame are sorted and fixed by cable cassette or metal cable clip. For horizontally laid cables, a fixed point is generally made up and down every 2m interval, for vertically laid cables should be fixed once every 11.5m interval, and the end of the change in elevation is also fixed.

 

 

6, pallet cable tray according to the requirements of power engineering construction standards and specifications should be excellent grounding, galvanized cable tray does not need a specialized grounding device, its own can be used as a grounding trunk; The bridge for non-metallic processing of the surface layer must have a specialized grounding device.
