The conveyor pan according to the present invention has a framework construction ( 1 ) having the bottom run ( 2 ) and an interchangeably constructed exchangeable tray ( 4 ) forming the top run ( 3 ), which can be lifted out, vertically supported on the framework ( 1 ). The framework construction ( 1 ) of the conveyor pan ( 50 ) has two roiled U-profiles forming the side walls of the conveyor pan, each of which has a vertically extending intermediate arm ( 11 ), an upper, outwards facing flange arm ( 12 ) and, lower outwards facing flange arm ( 13 ). The identically constructed but mirror imaged iron U-profiles ( 10 ), i.e. with the flange arms ( 12 ), ( 13 ) arranged facing away from each other, are joined firmly to each other by means of welded on plate strips ( 5 A, 5 B) at about half height on the inner wall ( 14 ) of the intermediate arm ( 11 ), whereby the plate strips ( 5 A, 5 B) leave an opening ( 6 ) inside the conveyor pan ( 50 ), which, with the exchangeable tray ( 4 ) removed, can serve as an inspection opening for the scraper chain, not shown, circulating in the bottom run ( 2 ) and equipped with scrapers. In the free space between the flange arms ( 12, 13 ) toggle pockets are welded in with a positive engagement, which additionally stiffen the iron U-profiles and the plate strips ( 5 A, 5 B) are supported by means of bottom run rails ( 20 ) on a continuous base plate ( 7 ) welded on beneath the iron U-profile ( 10 ).
