There is described a loading system, for use with a conveyor transfer system, which comprises a conveyor and a pusher assembly. The conveyor is located adjacent and parallel to a portion of a conveyor transfer system and is driven to travel at the same velocity as the adjacent conveyor transfer system. The pusher assembly comprises: a pusher member located adjacent an upper surface of the conveyor; a mounting member, the pusher member being rotatably mounted on an end portion thereof; a planetary gear fixed to the mounting member and rotatably mounted on a driven mounting which is rotated around a central axis; a restrained member rotatably mounted on the driven mounting and connected through links located on common parallel chords to the pusher member; and, a driven ring gear sharing said central axis and driven in the same direction as, but at a different speed to, the driven mounting. The relative rotational speeds of the ring gear and the driven mounting, and the gear ratio between the ring and planetary gears is selected such that the mounting member is rotated in an opposite direction causing the pusher member to move across the conveyor with a parallel component of velocity equal to that of the conveyor and a normal component of velocity to push an object from the conveyor onto said adjacent system.
