Conveyor having a track and rolling frames

摘要

In the rolling frames the wheels (2) can be swivelled in at least one pair of wheels. On the sides of its running surface (5) one rail (4) bears upwardly pointing, relatively low guide brims (6), the mutual spacing (a) of which is virtually equal to the width (b) of the wheel. By this means, the rolling frame is guided in the track system in an extremely accurate manner. <IMAGE>
