A weighing platform with a lattice load-bearing structure shaped spatially and made of load-bearing elements and connecting elements intersecting with them, affixed to a joint frame, where the load-bearing elements, in the place of intersection with the connecting profiles, have cuts in the shape adjusted to the shape of the connecting elements, and additionally the platform contains at least one load-bearing shell, measurement elements, regulated feet and connectors, where the connecting elements are located strictly in the cuts of the load-bearing structure at the depth, equal to height of the connecting elements and at the same time less than half of the height of the load-bearing elements, while to the bottom of the weighing platform at least two profile panels are fixed, with openings for the screw connectors, to which panels the measurement elements and regulated feet are fixed.

A grating including a bar assembly having bearing bars with a unique cross section connected to one another with crossbars. The bearing bars are generally hourglass-shaped in cross section and include a first region, a second region, and a third region interposed therebetween. The first and second regions flare outwardly away from opposite ends of the third region. The ends of the first and second regions are of a first width and the third region is of a smaller second width. First and second side sections of the third region connect to each of the first and second regions at an angle of greater than 90 degrees. Channels for the crossbars are defined in a first end of the first region of the bearing bar or form a hole extending from a first side section to a second side section of the third region of the bearing bar.
