A pair of rails arranged in parallel at predetermined intervals, a rung orthogonally arranged between the electric rails, and an electric In the configuration as a plate connecting the connecting end of the rail by the fastening means, the fixed ribs are attached to the upper and both sides of the rung, respectively, and the arrangement form corresponding to the fixed ribs of the rung on the inner side of the rail where both ends of the rung are in contact. Hanging plates protruded in the shape of ∪s with a gap between them are installed on the upper surface and one side, and the other side is formed with a flat support section cut in the shape of a 자. As a result, assembly time is greatly shortened and assembly is very simple, and the quality is excellent because warpage does not occur due to welding heat as in the prior art. Do.

However, the cable tray should be formed in each of the hanger and the support on the electric rail, and the fixed ribs must be formed at both ends of the rung to increase the manufacturing cost and bend the support by inserting the rib The disadvantage is that the process is cumbersome because it should prevent departure.

The present invention relates to an improved cable tray to solve the above problems.
