Definitions

  • the object of the present invention is a cable tray, whose characteristics allow multiple stacking, decreasing the volume of a set of trays, which optimizes transport costs very appreciably.
  • Grid cable trays consist of a set of longitudinal rods joined together by transverse rods every certain distance.
  • transverse rods In traditional cable trays the transverse rods have a "U" shape, with two of their sides parallel and joined together by a base perpendicular to both. Although for the function performed by this form is satisfactory, by when the mechanical strength of the tray is adequate, it is not so in terms of how to group them for packaging or transport, since it is necessary to stack them in inverted positions two to two , with a gap of considerable size between them.
  • transverse rods with their diverging side parts are unsatisfactory because the mechanical strength, ie the load capacity, is considerably reduced, so that at high load levels deformation occurs. progressive that makes its use unviable, or requires a greater thickness of the linkage and / or the number of rods, increasing the weight, the number of manufacturing operations and, consequently and significantly the price.
  • the present invention consists of a grid cable tray provided with a set of longitudinal rods joined by transverse rods, said transverse rods comprising:
  • each of said lateral parts is divided into three portions:
  • both lower and upper portions are perpendicular to the lower part; the upper portion is farther from the central plane of the tray than the bottom; A longitudinal rod is arranged in the angle forming the lower portion and the connecting portion.
  • It also comprises at least one longitudinal rod at the end of each of the upper portions of the transverse rods.
