Provided is a cable tray for high load. A cable tray for high load according to the present invention prevents deformation and damage by a structure of minimizing the action of bending moment or deformation due to action load even though a cable of high weight is placed, and can be stably used. A cable tray for high load according to the present invention includes a pair of side rails (10) which is separated from each other; and a vertical unit (20) which is vertically arranged between the side rails (10) and is separated by a setting gap. The side rail (10) has a U-shaped cross section and has a lower fixing terminal (11) inserted into the vertical unit (20); a connection terminal (12) which has a bar shape which is extended to the upper side of the lower fixing unit (11) and has a protrusion (121) which is formed on the inside of the center part and protrudes to the inside; and an upper fixing unit (13) which is horizontally formed on the upper end of the connection terminal (12). Deformation and damage due to the load of a cable placed on the vertical unit (20) can be prevented while the load applied to the connection terminal (12) of the side rail (10) is absorbed by the elastic deformation of the protrusion (121). |
