Abstract
A pan section for combined conveying and winning apparatuses having a bottom run and a top run for guiding driver elements of a conveyor chain, as well as a welded frame structure which has two side cheeks which consist of one-piece rolled profiles. The rolled profiles have a constant profile shape with a bottom leg and a top leg, which are angled outwards in the assembled state, and an intermediate leg being provided with an offset for supporting and welding at least one intermediate plate. The pan section further includes a substructure connected to the bottom leg of the rolled profiles to connect both bottom legs to one another at a distance from the intermediate bottom. The substructure also has mounting pieces positioned at the ends below the bottom legs for transverse-force transmission means.
