The conveyor's main part (4) has two arms (4a,4d) whose facing sides (4o,4p) have skids or rollers (2) positioned in pairs crosswise. The rollers, in the form of cylindrical wheels (2a,2b,2c,2d), are spaced apart in the arms' direction of travel so as to accommodate a guide rail (10) between them. The side surface of each wheel facing the opposite wheel forms the wheel flange. At least one of the two arms has a pin (4e)protruding especially at right angles to the arm's direction of travel. |
