<p>The conveyor consists of a flat surface rail with a predetermined path (1) which supports trolleys (c). The trolleys are coupled together by limiting couplings located at one end, which allows each trolley to swivel sideways to follow the rail. The trolleys are propelled along the rail by a motor driven endless belt (15) running between end wheels (16). Each trolley has two top and bottom rollers riding on either side of the rail. Each roller has two side walls and a central running surface of a larger width than the rail, to rest on it.</p> |
