20110139587 | CONVEYOR PAN WITH CHANGEABLE TROUGH, AND A CHANGEABLE TROUGH - A conveyor pan for a mining conveyor having a substructure with two side elements and an intermediate floor as well as a changeable trough forming a top strand and being detachably and exchangeably fastenable to the substructure. The trough having side profiles, each with a top web, and the top strand fastening means including screw bolts being fixable in place on the substructure. In order to ease an exchange of the trough, at least the top web of one side profile is provided with a plurality of open-edged indentations, in which there are welded holding strips, which project laterally over the top web and are provided with a plurality of bolt holes for the passage of a plurality of screw bolts. | 06-16-2011 |
20110220466 | PAN SECTION - 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. | 09-15-2011 |
20120031210 | RACK ARRANGEMENT FOR UNDERGROUND WINNING INSTALLATIONS AND BEARING BRACKET THEREFOR - A rack arrangement for underground winning installations having bearing brackets being fastenable at pan sections of a face conveyor and which have two pin holes each, and having rack bars being detachably fastenable to the pin holes of adjacent bearing brackets via pin connections having connecting pins. In order to design the rack arrangement and the bearing bracket for easier fitting and to improve the interplay between bearing bracket and rack bars in operational use, both pin holes are designed as an elongated hole for accommodating the connecting pin | 02-09-2012 |
