A two part endless conveyor (10) which is adjustable between an in-line operative position, and a folded transport position, and which comprises: a first conveyor part (11) which is adapted to be mounted at a first end (13) on the frame of a materiel handling apparatus; a second conveyor part (14) which is adjustably mounted at a first end (15) on an opposite second in which the second conveyor part (14) forms a prolongation of the first conveyor part (11) and so that the opposite second end (17) of the second conveyor part (14) forms a discharge end of the conveyor (10), and a transport position in which one of the conveyor parts (11, 14) underlies the other conveyor part and extends generally parallel thereto; and a folding mechanism (18) which interconnects the second end (16) of the first conveyor part (11) to the first end (15) of the second conveyor part (14), said mechanism comprising: a coupling block or linkage (18) which interconnects the second end (16) of the first conveyor part (11) and the first end (15) of the second conveyor part (14) via a respective one of a pair of pivots (20); and a pair of linear actuators (21) each associated with a respective conveyor part (11, 14) and extending between a mounting point (22) on the conveyor part and a connection (23) to the coupling block (18), each actuator being operative to rotate the coupling block (19) through approximately 90 DEG about the respective pivot (20), whereby the folding mechanism (18), under the action of the two linear actuators (21), can adjust the conveyor parts (11, 14) between the in-line operative position and the folded transport position.
