<p>A supporting installation for supporting a number of turns extending helically one above the other in a belt pile and included in an at least partly self-supporting conveyor belt (2) , comprising an inner supporting structure (8) which, together with an inner chain (5) supported by and movable along the same, defines an inner chan- nel (12) , in which one or more inner bearing elements (14) are arranged, which inner chain (5) is adapted to support a radially inner lateral edge of a lowermost turn of the belt pile, and an outer supporting structure (9) which, together with an outer chain (6) supported by and movable along the same, defines an outer channel (13) , in which one or more outer bearing elements (15) are arranged. The outer chain (6) is adapted to support a radially outer lateral edge of the lowermost turn of the belt pile. The inner and outer bearing elements (14; 15) are arranged for transfer of vertically downward forces from the respective chains (5; 6) to the associated supporting structure (8; 9), and the inner bearing elements (14) are arranged for transfer of radially inward forces from the inner chain (5) to the inner supporting structure (8) . The installation is characterised in that each chain (5; 6) comprises abutment surfaces which form a radially outer side wall (23) of the inner channel (12) and the outer channel (13) respectively, and that the outer bearng elements (15) are arranged for transfer of radially inward forces from the outer chain (6) to the outer supporting structure (9) .</p> |
