A workpiece elevator for moving plural workpieces from an intake station vertically to an elevated discharge station. The workpiece elevator includes a bucket assembly which is pivotable in response to engagement with cam bars such that in one rotated position, the bucket engages the workpieces and carries them to the discharge station where the bucket is rotated to a discharging position. The bucket assembly includes a pair of cam followers disposed on opposite sides of a plate which engage elongated cam bars affixed to the elevator frame. Means are also provided for limiting the angular range of motion of the bucket assemblies. The elevator in accordance with the second embodiment includes means for enabling the elevator to be easily modified to accommodate different configurations and sizes of workpieces. A pair of separated channels are mounted to the frame amd extend between the intake and discharge stations to laterally support the workpiece. Further, means are provided for varying the number of workpieces loaded onto the bucket assembly, thereby enhancing the range of application of the elevator.
