ABSTRACT:
An article carrier (1) includes a mount (3) for mounting the article carrier to a conveyor. A carrier frame (4) is located over the mount and is movable about a pivot (5) so as to be locatable in a carriage position, in which articles (2) may be supported on the carrier frame (4), and an ejection position, in which articles (2) are ejected from the carrier frame (4). The apparatus further includes a locking member (6); wherein when the carrier frame (4) is located in the carriage position, the locking member (6) is locatable in a first position that prevents movement of the carrier frame (4) about the pivot (5) and is movable into a second position that releases the carrier frame (4), allowing the carrier frame (4) to move about the pivot. When the locking member (6) is located in the first position to prevent movement of the carrier frame, the locking member is not under load. The article carrier (1) may be used as part of a grading apparatus.
