<p>The conveyor plant has driven carrier wagons, which run with rear and front rollers in upper and lower parallel profiled guide rails. At front and rear of the truck (FW), one roller is formed as a drive roller (FR), moving above the associated rail (LS), while the other roller is formed as a support roller (SR), moving below the other rail (LS). Drive rollers and support rollers are positioned diagonally opposite to each other. The distance (a) between the side of the truck, and the drive roller positioned on the opposite truck side is smaller than the clear distance (b) between the rails. In curved sections, the distance between the rails increases towards the centre of the curve. Drive rollers and/or support rollers are profiled for a slide guidance.</p> |
