为加速农田基本建设,修建高产稳产大寨田,解决土石山区石方装车机械化问题,昔阳农具厂为大寨大队制造了一台起重吊石机。该机是在少先式起重机的基础上试制的。生产实践表明,起重吊石机在解决用人工抬石装车的繁重体力劳动方面是有效工具之一,深受大寨贫下中农欢迎。该机制造简单,操作容易,使用可靠,成本较低,比人工装车提高工效2～3倍。 In order to speed up the construction of farmland, build Dazhai with high and stable yield, solve the problem of mechanized stone loading in rock and mountainous areas, Xiyang Farm Machinery Factory has built a crane for Dazhai Brigade. The machine is trial-based on the basis of less first-type cranes. Production practice shows that cranes are one of the effective tools in solving the heavy manual labor of loading rocks manually and are welcomed by the poor middle peasants in Dazhai. This machine is simple in manufacture, easy to operate, reliable in use and low in cost, and improves work efficiency by 2 to 3 times than manual loading.
