Excerpts from the report Summary: Storage space utilization is an important consideration to the operators of apple storages because it affects their returns for performing all operations in connection with storing and packing apples. Different types of materials-handling equipment which handle unit loads of different sizes govern to a great extent the volume of apples that can be stored in a given space. In this study three sizes of storage rooms were selected. Two of these rooms are of conventional design; they are typical of many found in older multiple-story plants in which clamp-type 2-wheel hand trucks are used for performing handling operations. One room is of modern design, suited for industrial trucks. Important variables considered in determining the amount of storage space that could be utilized in these rooms are: (1) Size of unit load; (2) aisle space; (3) stacking height; (4) type and kind of refrigeration; (5) air circulation used; and (6) spacing and size of posts and girders.
