 
					Introduction :
The
 design concept of the intensive three-dimensional warehouse breaks 
through the bottleneck of the low plane utilization rate of the roadway 
stacker crane warehouse and the low vertical space utilization rate of 
the “forklift and shuttle board” type high position racking warehouse. 
It
combines shuttle board and stacker crane 
smartly. The shuttle board can be understood as a transport trolley that
 can travel inside a dedicated shelf. After the goods are placed in the 
specified space, they are automatically returned to the starting point 
and deliver the next batch of goods. Compared with automated stereo 
warehouses, equip with a roadway stacker crane at one end or both ends, 
so that the land area of the middle roadway stacker crane can be used to
 arrange the shelves and improve the storage quantity of goods. And at 
the same time it can arrange multi-storey shelves in a limited space, to
 use the roadway stacker carne to complete the storage and retrieval 
work with the shuttle board, with high vertical and planar space 
utilization. It is applied in the food industry widely.
