gravity-driven roller conveyors // user information 55 Planning a manual conveyor system select a conveyor type based on the weight and characteristics of the material being conveyed determine the track width and axle distance based on the size of the smallest object that will be conveyed we would be glad to consult with you in more detail about custom solutions that go beyond these standard systems Selecting the proper pitch and axle spacing The conveyed goods must rest on at least three rollers in order to ensure that they are conveyed smoothly and do not tip over. The distance or pitch between the axles refers to the distance between the center points of adjacent rollers. Minimum pitch: size of smallest conveyed good divided by 3 (e.g. 250 mm / 3 = 83 mm: select 75 mm pitch). Smaller axle spacing should be selected when the material being conveyed will be loaded unevenly. Selecting the arrangement of the support frames Supports are usually set apart at a distance of approximately 1,500 – 2,000 mm. The main reason for this is the track load supports are provided as needed along a track length at the joints between two t conveyor segments for 90° bends, the bend should also be supported in the middle (at 45°) the support frames are set back slightly from the ends of the track pitch “Transporting goods with downward gradients from 2 to 5 %” flat base longitudinal bars belt battens lattice base
