<p>In order to be able to produce for the improvement of single part inventory and shipment as well as easing the handling in the production and/or assembly of a frame for band conveying devices formed from longitudinal beams held together by cross beams, the longitudinal beams of which in each case are formed as sections open towards the conveying means with outer web and top web extending away from its upper end, with as few single parts as possible and without cost-intensive connection elements with despite adequate load-bearing capacity significant weight reduction simply, quickly and conveniently in the manufacturing plant for delivery ready assembled or at the site of use particularly rationally despite universality to a very large extent with regard to the most widely differing conveying width and length and different load-bearing capacity properties from sections of the simplest possible and accordingly most inexpensive cross-sectional contouring, the longitudinal beam sections possess according to the invention in each case at the free end of their top web a connection flange extending away downwards and both longitudinal beam sections are connected with one another by means of a distance piece formed as U or C section, the two side or edge webs of which extending away from its central web approximately complementarily to the adjoining longitudinal beam section connection flange are in each case connected with this.</p> |
