Logistics tray of the "past life"

 Tray to the modern logistics industry benefits are mainly reflected in: can achieve the packaging of the unit, standardization and standardization, to protect the goods, to facilitate logistics and business flow.

Tray circulation originated in war

From the world point of view, the first use of the tray originated in Australia, but the tray in the circulation between enterprises originated in the United States. The Pacific War in the 1930s, the US military for the first time the use of trays to improve the efficiency of cargo handling to ensure the supply of logistics supplies. In 1946 the Australian government established a federal handling equipment sharing system, the standard pallet utilization rate of up to 95%, and become the world's largest use of standardized pallet countries, and has the largest hemisphere pallet sharing system. Later, the tray in the world has been widely used, is considered the 20th century logistics industry, one of the two key innovations.

The first countries in Europe to carry trays are Sweden (1947), followed by Switzerland (1951), the success of the two countries pallet joint venture system, the other countries in Europe had a significant impact, leading to France, Germany and many other European countries Have set up their own domestic pallet joint venture system.

The size of the tray

There are six sizes of current international standards for trays. From the perspective of international trade, each national interest group wants other countries to adopt their own tray standards so that their goods can make full use of their country's logistics equipment and facilities, low cost Successfully enter its market, but do not want to change the tray because of its country standards, and then change the industry standard to share any price. So a country generally does not easily change its own tray size standards. From the point of view of trade in goods, the tray standard is a trade technical barrier that can play a role in promoting the export of goods or protecting the domestic market.
  
Classification of trays

One, flat tray
Ping tray the most widely used, the use of the largest number, the best versatility. Flat tray can be subdivided into three types:
① According to the table classification. Single-sided, single-sided use, double-sided use and airfoil four;
② According to forklift fork way classification. There are one-way fork into the type, two-way fork into the type, four-way fork into the three;
③ According to the classification of materials. Wooden flat pallets, steel flat pallets, plastic flat pallets, composite pallets and paper pallets.

Second, the column tray
Column pallet is divided into two kinds of fixed and removable, the basic structure of the four corners of the tray has a steel column, the top of the column can be connected with beams to form a frame type. The main role of the column tray, one is to support the weight of the column, to the high stack; the second is to prevent the goods placed on the tray in the transport and loading and unloading process collapse occurred.

Three, box tray
Box-type tray is surrounded by a side plate of the tray, and some of the box on the roof, and some no roof. Box board has a fixed, folding, removable three. Surrounded by the fence plate plate, grid and network type, therefore, around the fence for the fence type box tray also known as cage tray or warehouse cage. Box-type tray protection ability, to prevent collapse and cargo damage; can be loaded shaped can not be stable stacking of goods, a wide range of applications.

Four, wheeled tray
Wheeled trays Compared to pillars and box trays, the lower wheels are smaller. Therefore, the wheeled tray shows a short distance to move, self-handling or rolling down the type of loading and unloading and other advantages, wide range of applications, strong applicability.

Five special special tray
Due to the high efficiency of the pallet operation, safety and stability, especially in some occasions require rapid operation, highlight the importance of using the tray.
