The pans are arranged end to end, and the rack bar haulage system includes a plurality of rack bars, each rack bar end including a pillar portion extending downwardly. One rack bar is adapted to be mounted adjacent an end of a line pan, and another rack bar is adapted to be mounted adjacent the adjacent end of the adjacent line pan. The haulage system also includes a chain-link, the chain-link surrounding and engaging the two adjacent pillar portions on the ends of the one rack bar and the adjacent other rack bar. The chain-link is adapted to extend over the adjacent ends of the line pans. The haulage system also includes a clog for receiving the rack bar, the clog including an extension that engages the chain-link and traps the chain link between the extension and the rack bar. |
