The Ruzaevsky Chemical Engineering Plant (AO "Ruzkhimmash") has patented a utility model that increases the carrying capacity of a flatcar. This is achieved by changing the design of the shortened center sills.
A standard car frame includes headstocks, side sills, bolster beams, crossbeams, and shortened center sills. The authors proposed making the top shelf of the shortened center sill T-shaped – with longitudinal and transverse sections. The transverse section of this shelf is simultaneously connected to the side sills at the points where the fitting stops are installed and becomes the top shelf of the crossbeam. As a result, the crossbeam acquires a box section, which significantly increases its rigidity and strength.
Such an engineering solution allows for more efficient load redistribution and increases the useful carrying capacity of the flatcar without changing its external dimensions. The development can be used in the production of new freight cars and in the modernization of existing rolling stock. The patent has already been obtained.
Earlier, Ruzkhimmash invented an improved brake equipment mounting assembly for flatcars. The development allows increasing the strength of the connection while maintaining the compact placement of parts. This refers to the dead point link mounting assembly – one of the key parts of the brake rigging. This is where stresses often occur that can lead to breakage. Ruzkhimmash engineers proposed a new bracket design that solves this problem.
