A conveyor provided with a sidewardly spaced pair of elongate roller systems (61, 62) which are downwardly inclined and are maintained in rolling engagement with legs (56, 57) associated with outer edge portions of a pallet. A conveying arrangement (71) extends longitudinally midway between the roller systems (61, 62) and includes a vertically movable roller unit (72) actuatable so that, when raised upwardly the rollers (81) engage and lift a center portion (58) of the pallet (55) to permit gravity-urged movement downwardly along the conveyor. The roller unit (72), when lowered, permits the center portion of the pallet (58) to engage a stationary brake structure (91).
