一般的叉车即使装上三层的特殊门架,起升高度也只能达到6米,这时还要减小它的额定载重量。日本输送机公司设计的专为高度为6～12米的中层货架仓库用的叉车可将1吨～1.5吨的货物起升到9米的高度。这种叉车在货架之间的通路与普通叉车相比只要约50～60%,而装载高度可超过普通叉车40～50%。 Even if the general forklift fitted with three-tier special gantry, the lifting height can only reach 6 meters, then reduce its rated load. Japanese forklift company designed specifically for the height of 6 to 12 meters in the middle of the warehouse with forklifts can lift 1 to 1.5 tons of cargo up to 9 meters height. This kind of forklift has about 50 ~ 60% of the passage between the shelves compared with the normal forklift, and the loading height can exceed 40 ~ 50% of the ordinary forklift.
