辊轮式货架
一边通道存货，另一边通道取货。料架出货方向向下倾斜，货物在重力作用下向下滑动。可实现先进先出，并可实现一次补货，多次拣货。
Roller racks
One passage for warehouse and the other passage for ex-warehouse. The shelves are designed to be tilt, so the goods can roll down the racks by gravity. The roller racks can achieve FIFO, replenishment at one time and multiple picking.
