Support bracing for railway wagon covers and sliding panels

摘要

The construction features at least two vertically disposed main frames (7) located between an upper spar (4) at the edge of the roof cover (2) and a lower spar (3) at the bottom of the side wall (I). At the bottom of the vertical frame nearer to the end wall (12), a support roller (9) is mounted so as to interact with a longitudinal runner (11). The second vertical frame has a guide with lateral contact surfaces bearing upon the runner. Beyond the two main frames is a smaller secondary frame (8) also equipped with a support roller.
