为了满足小型混凝土预制构件和其他小件物品起重安装、装卸车、堆码和短距离搬运的需要,湖南省建筑研究设计院以一吨机动翻斗车底盘为基础,设计了QL1轮胎式起重机。两年来在湖南省湘阴工程机械厂进行了三代样机试制。通过性能和应力测试、工业性考核证明,QL1轮胎式起重机结构简单、机动灵活、性能良好、成本低廉,适用于中小型混凝土预制厂、建筑工地、市政工程及车站、码头、仓库货场等,达到了设计要求。湖南省城乡建设环境保护厅于1983年
In order to meet the needs of small concrete prefabricated units and other small items lifting installations, loading and unloading vehicles, stacking yards and short-distance handling, Hunan Provincial Architecture Research and Design Institute designed a QL1 wheeled crane based on a ton of motorized dump truck chassis. In the past two years, prototypes of three generations of prototypes have been carried out at Hunan Xiangyin Engineering Machinery Plant. Through performance and stress tests and industrial assessments, the QL1 tire-type crane has a simple structure, flexible maneuverability, good performance, and low cost, and is suitable for small and medium-sized concrete precast plants, construction sites, municipal works, and stations, docks, warehouses, and freight yards.
