例如生产工程机械的美国卡特皮勒公司金属结构厂购置了一条以桥式起重机为主

For example, the metal structure factory of Caterpillar Inc., which produces engineering machinery, has purchased an automatic material handling system mainly based on bridge cranes. It is used for automatic loading and unloading of steel plate shot blasting, cutting and storage. Operational efficiency has increased by 65%. The Toshiba Hamagawa Kawasaki Plant in Japan uses a material conveying system composed of fully automatic bridge cranes to move the fixtures and workpieces on the flexible processing line, transport the rough for the machine tool or send the processed parts to the next process or warehouse. These crane-moving systems that move in space replace the automatic guided trucks that were commonly used in the past, so that the floor space of the workshop is fully utilized.

For example, the metal structure plant of Catterpell, inc., which produces construction machinery, has acquired a automatic material handling system based on a bridge crane for blast handling, cutting and storage of steel plates, which is 65 percent more efficient than the original single-machine operation. The material handling system consisting of a fully automatic bridge crane is used at the Kawasaki plant in Japan to carry fixtures and workpieces on flexible processing lines, transport blanks for machine tools or deliver processed parts to the next process or warehouse. These space-moving crane handling systems replace the automatic guided carriers that were commonly used in the past, making full use of the floor area of the workshop.

For example, the metal structure factory of caterpillar company in the United States, which produces engineering machinery, purchased an automatic material handling system mainly composed of bridge crane, which is used for the automatic loading and unloading operations of shot peening, cutting and warehousing of steel plates. The working efficiency of the system is 65% higher than that of the single machine. The material conveying system composed of full-automatic bridge crane is used in Kawasaki factory in Toshiba, Japan, to carry the clamps and workpieces on the flexible processing line, to transport the workpieces for the machine tool or send the processed parts to the next process or warehouse. These crane handling systems which move in the space replace the automatic guided vehicles which are usually used in the past, so that the floor area of the workshop can be fully utilized.
