六十年代末,七十年代初,世界经济出现了一个高速发展阶段。随着生产的发展,物资和商品流通量急剧增加,流通费用在商品成本中所占的比重不断增大。为了适应商品流通和市场竞争的需要,促使不少国家探索新技术来降低商品的流通费用,提高仓储效率,减少流动资金的积压和提高单位面积存贮能力来增加利润。而商品存库保管系统在整个商品流通环节中占很大比重。在这方面许多国家研究出了不少适用于各类商品堆放的储存机具,并配备了现代化的科学和管理技术,提高了装卸和选捡、分拣机具的自
In the late 1960s and early 1970s, the world economy had a period of rapid development. With the development of production, the circulation of goods and commodities has increased drastically, and the proportion of circulation costs in the cost of goods has continued to increase. In order to meet the needs of commodity circulation and market competition, many countries have explored new technologies to reduce the circulation costs of commodities, improve storage efficiency, reduce the backlog of working capital and increase the storage capacity per unit area to increase profits. The storage system of commodity deposits accounts for a large proportion of the entire circulation of goods. In this regard, many countries have developed a number of storage devices that are suitable for the stacking of various types of commodities, equipped with modern science and management technologies, and have improved the efficiency of loading, unloading, and selecting and sorting equipment.
