ABSTRACT:
Apparatus for propelling a succession of pallets in a longitudinal direction has a plurality of pawls for pushing the pallets and spaced apart on a pair of endless drive chains each having a portion extending parallel to a pallet guide means. Each pawl is arranged to move in such a way that in use it engages one of the pallets to push it along the guide means and disengages from the pallet further down the guide means, the movement of each pawl being controlled by an associated cam follower wheel cooperating with one of a pair of longitudinally extending cam tracks. The cam follower wheel can be laterally moved on a shaft to select the appropriate cam track for the type of pallets to be conveyed, so that the apparatus can be easily adapted to e.g. different length pallets.
