  27. Warehouse Configurations

  28. Warehouse Physicals • Storage systems • Pallet storage • Non-pallet storage • Vehicles

  29. Configuration Variations • Rack selection and layout may vary due to space limitations • Three standard layout variants • Conventional - 12 foot aisle • Narrow aisle - 8 to 9 foot aisle • Very narrow aisle - 5 to 6 foot aisle

  30. Conventional Layout • 12 foot aisles • Counter balance fork trucks • Least expensive equipment • Limited to four or five levels high
