Explain and introduce several common types of three-dimensional warehouses.

Automated three - dimensional warehouse, also known as automated stereoscopic warehouse, is a mode of logistics warehouse. It uses stereoscopic warehouse equipment to realize the rationalization of the upper layer of the warehouse, automatic access, transportation and sorting of goods, with simple operation. The automated three - dimensional warehouse is currently a form with a relatively high technical level. The main body of the warehouse is composed of shelves, aisle - type tower cranes, inbound and outbound workbenches, automatic inbound and outbound systems, and operation control systems. The shelves are buildings or structures with steel structures or reinforced concrete structures, and there are standard - sized goods location spaces in the shelves. The aisle tower cranes complete the work of storing and taking out goods through the aisles between the shelves. The management adopts computers, bar code or RFID technology. With the expansion of the application scope of automatic warehouse systems, in order to cope with various application scenarios, various types have emerged. Let's take a look at what common three - dimensional warehouses there are. Tower crane three - dimensional warehouse It mainly uses tower cranes equipped with forks to pick up goods, and the platform runs along the track along the pillars of the tower crane to the designated position. Common ones include container stacking stereoscopic warehouses and micro - load automated stereoscopic warehouses with silos as the storage unit, etc. Tower crane stereoscopic warehouse and multi - layer shuttle three - dimensional warehouse
