A truss (fr. Ferme, from lat. Firmus durable), in structural mechanics, a rod system that remains geometrically unchanged after replacing its rigid nodes with hinged ones. In the elements of the truss, in the absence of misalignment of the rods and off-node loads, only tensile-compression forces arise. Trusses are formed from rectilinear rods connected at nodes. Sokol Elevator Equipment Plant carries out design, manufacture and installation of steel structures for trusses.
