Two types of warehouse

Main Warehouse:

A warehouse is a commercial building for storage of goods. Warehouses are used by manufacturers, importers, exporters, wholesalers, customs and many others. They usually have loading docks to load and unload goods from trucks. Sometimes warehouses are designed for the loading and unloading of goods directly from railways, airports and seaports. They often use a cranes and forklifts for moving goods, which are usually placed on ISO (International Organization for Standardization) standard pallets loaded into pallet racks. Stored goods can include any raw materials, packing materials, spare parts, components, or finished goods associated with agriculture, manufacturing and production.

In the warehouse, there are many of the transportation to bring the goods from one point to another point. For example is forklifts, cranes, drum lifters, chain hoists, flammable storage cabinets, electronic workbenches, industrial shelving, lift tables, pallet trucks, plastic storage bins, platform trucks, rolling ladders, utility carts and more others.

The function of each one material handling in a warehouse is differences. Firstly the most familiar material handling in the warehouse is a forklift. A forklift truck also called a lift truck, a fork truck, or a forklift is a used to lift and move materials for short distances. The forklift was developed in the early 20th century by various companies including the transmission manufacturing company Clark. Forklifts have become the most important piece of equipment in manufacturing and warehousing operations until now.

                                           










          Secondly is crane. A crane is a tower or derrick equipped with cables and pulleys that can be used both to lift and lower materials and to shift them horizontally. Cranes are commonly employed in the construction industry and in manufacturing heavy equipment. Construction cranes are usually temporary structures, either fixed to the ground or mounted on a purpose-built vehicle. Cranes may either be controlled from an operator in a cab that travels with the crane, by a push button pendant control station, or by infrared or radio control.

Refrigerator Warehouse:                                       

Cold storage preserves agricultural products. Refrigerated storage helps in eliminating sprouting, rotting and insect damage. Edible products are generally not stored for more than one year. Several perishable products require a storage temperature as low as -25°C.

Ammonia and Freon compressors are commonly used in cold storage warehouses to maintain the temperature. Ammonia refrigerant is cheaper, easily available and has a high latent heat of evaporation but it is also highly toxic and can form an explosive mixture when mixed with oil containing high percentage of carbon. Insulation is also important, to reduce loss of cold and to keep different sections of the warehouse at different temperatures.

There are two main types of refrigeration system used in cold storage warehouses, a Vapour absorption system (VAS) and Vapour compression system (VCS). VAS, although comparatively costlier, is quite economical in operation and adequately compensates the higher initial investment.

The temperature necessary for preservation depends on the storage time required and the type of product. In general, there are three groups of products, foods that are alive (e.g. fruits and vegetables), foods that are no longer alive and have been processed in some form (e.g. meat and fish products), and commodities that benefit from storage at controlled temperature (e.g. beer, tobacco).

There are state and local laws which regulate the cold store industry, requiring safe working conditions for employees, and operational procedures must be in accordance with these laws. Those companies which do their homework and prepare in advance for inspections and other routine enforcement protocols will be able to continue operating at full capacity, ensuring greater customer service and more product flow seven days a week.
