A conveyor comprises laterally spaced apart lifting/holding slats ( 12 ) and laterally spaced apart conveying slats ( 10 ) between the lifting/holding slats ( 12 ). The conveying slats ( 10 ) are advanced in a first direction for conveying a load and are retracted in a second direction for returning them to a start position. The lifting/holding slats ( 12 ) have lower portions ( 62 ) which reciprocate and upper portions ( 60 ) which move up and down. Cams ( 92, 94 ) operate in response to longitudinal movement of the lower portions ( 62 ) to raise and lower the upper portions ( 60 ).
