The construction device forms the cable tray with longitudinal wires (1,3) supported at regular intervals by transverse brackets (2) with a 'U'-shaped profile. The assembled tray has a bottom (1A) and two sides (1B). The upper longitudinal wire is bent into troughs (4A) at regular intervals along its length. The section of the bottom part of the trough (5) is machined to be rectangular. The transverse brackets have a loop at either end (2A) that fits over the bottom of the trough. The profile of the loop matches the profile of the wire at the bottom of the trough, providing a close fit that reduces movement between the longitudinal sides and the transverse brackets, increasing the rigidity of the constructed cable tray.
