ABSTRACT:
A rack assembly for allowing movement of a winning machine utilized in underground, long-wall mining operations. The rack assembly is comprised of a plurality of rack sections positioned end-to-end and suitable for attachment to trough sections of a face conveyor. The rack sections correspond in a one to one relationship to the trough sections and have lengths slightly greater than the associated trough sections. Toggles connect adjacent rack sections and maintain the adjacent rack sections such that end faces of the rack sections are maintained contiguous to one another, preventing relative longitudinal movement between the adjacent rack sections. The toggle, however, allows limited, relative vertical and horizontal movement between adjacent rack sections to allow positioning of the rack sections along a mine floor.
