The load of cable tray vendors is divided into load, dynamic load and additional load.
Static load refers to the type, root number, outer diameter weight / unit length of the cable laid in the cable tray, which is listed and counted according to the different routes of cable laying.

Dynamic load refers to the weight of construction and maintenance personnel in the process of installation and maintenance of cable tray.
For light cable tray, dynamic load is generally not considered, that is, people are not allowed to stand (walk) on the bridge.
If people need to be considered, the span should be reduced appropriately.

The external additional load only refers to the load formed by snow, ice, wind and electromagnetic force, which is related to the natural meteorological conditions of the installation site and the nature of the charged body, and should be calculated according to various conditions in the design.
