最近,我参加了日本小松制作所举办的液压挖掘机技术讲座。讲座除了介绍其产品,小松产液压挖掘机PC-400型的技术改进及如何开展技术服务等以外,还以大量的资料,从液压挖掘机理想的工作性能、在世界工程机械总量中占有率的迅速提高和飞速发展,充分说明液压挖掘机是一种极有发展前途的机种。这种观点,对于我们在工程机械的生产中如何调正各种机械的比例及发展速度,重视液压挖掘机的生产和使用,不无参考价值。因此,我在此作一个简要的介绍。一、80年代液压挖掘机在全世界的需求量有了很大的发展。图1表明,1982年全世界仅拥有液压
Recently, I participated in a hydraulic excavator technology seminar organized by Komatsu Seisakusho Japan. In addition to introducing its products, Komatsu’s PC-400 hydraulic excavator technology improvements and how to carry out technical services, etc., in addition to a large amount of information, from the ideal working performance of the hydraulic excavator, the world’s total share of construction machinery The rapid increase and rapid development fully demonstrated that the hydraulic excavator is a very promising model. This point of view, for us in the production of engineering machinery, how to adjust the proportion of various machinery and development speed, attach importance to the production and use of hydraulic excavators, not without reference value. Therefore, I will make a brief introduction here. First, in the 1980s, the demand for hydraulic excavators in the world has been greatly developed. Figure 1 shows that in 1982 the world only had hydraulic pressure
