郎运治同志是冶金建筑系统最早的挖土机司机之一,曾出席过全国群英会。在多年的实践中积累了不少经验,他根据挖掘机的特点,详细地作了研究部署,掌握了机械的性能,把大型土方挖掘机使用在刀刃上,因而充分发挥了它的作用。土方机械是施工中的重武器,把它们使用得好,是提高劳动生产率的一个重要环节。本刊在第三期将继续发表他在拉铲方面的操作经验,供有关人员参考。
Comrade Lang Yunzhi was one of the earliest excavator drivers in the metallurgical building system and had attended the National Elite Games. In the years of practice, he has accumulated a lot of experience. According to the characteristics of the excavator, he made detailed research and deployment, mastered the performance of the machine, and used the large-scale earth excavator on the blade, thus fully playing its role. Earth-moving machinery is a heavy weapon in construction. Using them well is an important part of improving labor productivity. In the third issue, the journal will continue to publish his operational experience in pulling shovels for the reference of relevant personnel.
