ABSTRACT:
During the haulage of a conveyor unit (3), a floor chain (6) of a shunting track (2) is moved over a pitch distance (PZ) which is slightly larger than the length of a conveyor unit (3) and which is selected such that, after the movement, a catch element (7) is in a position ready to carry along a pin (11) of a subsequent conveyor unit (3) to be hauled, until the conveyor unit (3) reaches an intermediate position whereby it is still situated with a portion thereof in the path (14) of the conveyor units (3) which have not been hauled. When the subsequent conveyor unit (3) must also be hauled, the floor chain (6) of the shunting track (2) is again moved over the above-mentioned pitch distance (PZ). When the subsequent conveyor unit (3) has to further follow the main track (1), the floor chain (6) of the shunting track (2) is moved over such an intermediate distance (X) that the conveyor unit (3) in the intermediate position is brought outside the path (14) of the conveyor units (3) which have not been hauled, after which the floor chain (6) is moved in the reverse direction over a return distance (Y) until the catch element (7), which would normally carry along the pin of a subsequent conveyor unit (3) to be hauled, is in the position in which it is ready to carry along the pin (11) of such a subsequent conveyor unit (3), whereby the conveyor units (3) are released by the catch elements (7) on the shunting track (2).
