ABSTRACT:
A walking-beam conveyor has a pair of horizontally and longitudinally extending fixed beams flanking a central movable beam. A plurality of support yokes each have a relatively low central part underneath the movable beam and a pair of relatively high side parts horizontally flanking the movable beam. Rollers are provided on the low parts for supporting the movable beam thereon for longitudinal movement relative to the fixed beams and yokes, the yokes in turn being longitudinally nondisplaceable relative to the fixed beams. Respective vertically expansible lifters are engaged between the ground and the high parts for lifting the movable beam with the yokes relative to the fixed beam. A longitudinal conveyor is hung on the movable beam and has a pinion meshing with a rack carried directly on the movable beam for horizontal displacement of the movable beam relative to the fixed beams.
