Abstract: In order to increase the efficiency of space utilization in a palletized goods store in which loaded pallets (1) are arranged in rows (2, 3) with alleys (4) therebetween, each loaded pallet (1) is carried on a wheeled trolley (7A). Where it is required to introduce a loaded pallet (1A) into a space (10) present anywhere along each row (2), the wheeled trolleys are arranged to move transversely of a row whereby the loaded pallet (1A) can first be transported by a fork lift truck (11) down an alley (4) opposite to said space (10), and then moved transversely on a wheeled trolley (7A) into said space (10). In this manner, it is unnecessary for the truck (11) to effect a quarter-turn in the alley (4) whereby the latter can be of a much smaller width than normal. Where the store is to be operated on a first-in, first-out basis, the wheeled trolleys in a row are arranged for movement longitudinally of the row.
