A walking beam conveyor having a cam at only one of its ends. The conveyor includes a framework, a longitudinally extending beam having proximal and distal ends, and a plurality of supports freely pivotally mounted in the framework for supporting the beam. The supports carry the beam in such a manner as to allow the beam to move longitudinally of the conveyor with respect to the supports. A first follower, movably mounted in the framework, follows the cam and a first linkage apparatus connects the first follower to the supports. The supports pivot about their connections to the framework in response to movement of the first follower to move the beam transversely of the conveyor, e.g., vertically. The supports engage an equal plurality of beam guides to which the beam is attached. A second follower, also movably supported in the framework, and second linkage apparatus coupled to the second follower and the beam, move the beam longitudinally of the conveyor, e.g., horizontally.
